Fig. 1. Fig. 2. Fig. 3. Pre-Columbian Musical Instruments in America.—In a recent article in the Popular Science Monthly (November, 1898), entitled Was Middle America Peopled from Asia? I insisted that if there had been any invasion, peaceful or otherwise, sufficient to have affected even in the slightest degree the arts, customs, and religious beliefs of middle America, then, associated with these influences, we should find traces of Asiatic utensils, implements, structures, such as sandals, weapons, pottery, wheels, plows, roofing tiles, etc.; in other words, just those objects most intimately associated with man. I especially considered the absence of stringed musical instruments and coincided with Dr. Otis T. Mason in the belief that there was no evidence of a pre-Columbian stringed musical device. This question has been variously discussed and the following references bear on the subject: A short note in the American Antiquarian for January, 1897, by Dr. D. G. Brinton, entitled Native American Stringed Musical Instruments. The author frankly admits, however, that the cases cited may all have been borrowed from the whites or negroes. Mr. M. H. Saville in the American Anthropologist for August, 1897, described A Primitive Maya Musical Instrument, though he makes no pronounced statement of its pre-Columbian origin. Dr. Mason, in the American Anthropologist for November, 1897, discusses the question under the title Geographical Distribution of the Musical Bow, and in this paper says, "I have come to the conclusion that stringed musical instruments were not known to any of the aborigines of the western hemisphere before Columbus." In my paper I insisted that "had this simple musical device been known anciently in this country, it would have spread so widely that its Edward S. Morse. Rebreathed Air as a Poison.—The following extracts are taken from an article by Dr. John Hartley, in the Lancet: "The fresh-air treatment of consumption" appears to be made up of three essential factors: (1) the discontinuance of the supply of bacilli from without; (2) the supply of an abundance of nutritive material to the tissues; and (3) the supply of an abundance of fresh air uncontaminated by the products of respiration. This seems to mean that the tissues, if not too enfeebled, may be trusted to deal with the bacilli already present if their metabolism is kept going at high pressure. Fresh air is now the "official" remedy in the treatment of tubercle. Why is it so ignored in the case of other diseases? Has the pneumonic or bronchitic no need of special ventilation because his microbe is of a different breed? The air was intended not only for phthisical patients or patients suffering from pneumonia but for all—diseased and healthy alike—and it is still the natural medium in which the poisonous products of tissue metabolism excreted by the lungs are further broken down and rendered harmless. Dr. A. Ransome has done great service not only by his onslaught on "air sewage" but also by his coinage of the term; for a thoroughly good opprobrious epithet resembles a good wall-poster in its power of arresting and enchaining the attention of the many. It was long ago pointed out that certain constituents of expired air are intensely powerful nerve poisons. These considerations should surely make us look on rebreathed air and sewer gas, not as mere carriers of accidental poisons, such as influenza and pneumonia and the like, but as poisons per se, and I wish to be allowed to record a few very imperfect observations made by myself during some years past chiefly on the subject of rebreathed air, with certain inferences which I think tend, however feebly and imperfectly, to show that the poisons we expire have per se very definite effects on tissue metabolism and need not a mere perfunctory admixture with fresh air but very large and very continuous dilution before they are rendered innocuous—that is to say, innocuous to all; for while some persons appear to be almost immune, others seem intensely susceptible. The first observation I will allude to was made in the autumn of 1896, in cool weather. I had to take a long night journey by rail after a long and hard day's work. The train was full and the compartment I entered was close; so, as I was tired and fagged, I sat in the corridor by an open window, well rugged up, throughout the journey. The compartment was completely shut off from the corridor by a glass door and windows, through which I could freely inspect its occupants. Two remarkably fresh-complexioned, wholesome-looking young fellows got into the compartment at York. They formed a remarkable contrast to the pallid and fagged-looking travelers already there. The windows and ventilators were carefully closed, and the newcomers, with the rest, settled off to sleep and slept soundly for nearly four hours, with the exception of a few minutes' interval at Grantham. When aroused on nearing London they, like the other occupants of the compartment, were haggard and leaden-hued, their fresh color was entirely gone, and they looked and moved as if exhausted. I examined my own face in the lavatory mirror at the beginning and end of the journey and could see but little alteration in my color; if anything, it was rather improved by the end of the journey. The second case occurred early in 1897. I was asked to see a woman, aged about forty-eight years, who had been treated in a neighboring town for many weeks for bronchitis and asthma following influenza. She had relapsed about a week when I first saw her. She was then sitting up in bed; her face was leaden-colored, her skin was clammy and sweating, with a feeble, quick pulse, and the heart sounds were indistinguishable owing to wheezing; there was some crepitation at the bases. The temperature was about 101° F. The weather was cold, but after wrapping her up, with a hot bottle to her feet, the window was well opened. Her color improved in a few minutes and the sweating ceased soon after. But it and the The Utilization of Wave Power.—The utilization of the energy which goes to waste in the movement of water, in waves, tides, and waterfalls, has been a much-studied problem during recent years. The only one of these three phenomena which has as yet been at all extensively commercially harnessed is the waterfall. There have, however, been a number of wave and tide motors constructed. The most recent and perhaps the most promising of these is the type invented by Mr. Morley Fletcher, of Westminster, England. He has made a special study of the problem of motion of the sea, and has already successfully constructed a hydraulic pump, an electric motor, and a self contained siren buoy in which the energy is obtained entirely from wave motion. The great possibilities in this direction for cheap and efficient power plants have not been appreciated by seacoast towns, but it is stated in Industries and Iron, from which we have taken the above particulars, that Mr. Fletcher is at present devoting his attention to devising schemes and designing apparatus for pumping sea water for shore purposes, ore washing, driving electric machinery for town lighting and power plants, buoys for marking harbors with beacons and fog horns, and the many other purposes to which such a constant and inexhaustible source of energy is applicable. Dispersal of Seeds.—Having described in the Plant World some of the provisions of Nature for the dispersal of seeds, Prof. W. J. Beal adds that these various devices, besides serving to extend and multiply the species and promote its plantation on favorable soil, enable plants to flee from too great crowding of their own kind and from their plant rivals and parasites. "The adventurers among plants often meet with the best success, not because the seeds are larger or stronger or better, but because they find for a time more congenial surroundings. Our weeds, for instance, are carried for long distances by man and by him are planted in new ground that has been well prepared. Every horticulturist knows that apples grown in a new country, if suitable for apples, are fair and healthy, but the scab and codling moth and bitter rot and bark louse sooner or later arrive, each to begin its peculiar mode of warfare." So with peach trees and plums and their enemies. The surest way to grow a few cabbages, radishes, squashes, cucumbers, and potatoes is Commensals.—Curious associations are formed among animals for mutual aid in the struggle for existence. Some of them are societies of the same species, like those of ants and bees; colonies in which many individuals—as ascidians and bryozoa—join into a single mass and act as one; and associations of animals of different species constituting commensalism where both are benefited, or parasitism, when the advantage accrues to only one of the parties. The hermit crab and certain ascidians furnish very fine examples of commensalism. The hermit crab is known as an inhabitant of shells bereft of their proper owners. Some sea anemones also fasten themselves on shells, and seem to prefer those which have been adopted by hermit crabs. The association is shown by M. Henri Coupan, in La Nature, to be one of mutual benefit. The actinia defends the crab and its home against all intruders by means of its tentacles—veritable batteries of prickly stings; while the crab, with its long claws reaching out to catch whatever is good to eat, brings food within reach of the ascidian. Mr. Percival Wright, having taken the crab from a shell to which an ascidian had attached itself, found that the latter abandoned the shell in a short time. M. L. Faunt reversed the experiment, taking the ascidian away, when the crab deserted its quarters, found a shell with the ascidian on it, and occupied it very quickly. He further observed the maneuvers executed by the crab to secure the attachment of an ascidian to its shell. Sometimes a large ascidian will wholly cover a shell; or several smaller ones will spread themselves over the same shell so as to form a continuous envelope over it. The ascidians become so attached to their commensals as to seem unable to live without them, and even to die soon after being separated from them. Drift of Ocean Currents.—Of sixteen hundred and seventy-five floats bearing requests to the finder to return them which Prince Albert of Monaco dropped into the Atlantic during three research cruises, with a view to learning something of the movements of surface currents, two hundred and twenty-six were returned to him up to the year 1892. By working the course which each of them had probably been following, the prince undertook to draw a definite map of the currents. As the elements employed were always numerous for each region, he thinks his results were near the truth in its general lines. The floats landed on almost all the shores of the North Atlantic, from the North Cape to the south of Morocco, along Central America, and on the islands of Canaries, Madeira, Azores, Antilles, Bermudas, Shetland, Hebrides, Orkneys, and Iceland. None appeared as far south as the Cape Verde Islands. The drifts seem to indicate an immense vortex, beginning toward the Antilles and Central America with the Gulf Stream and the equatorial current; passing the Banks of Newfoundland at a tangent, it turns to the east, approaches the European coasts, and runs southward from the English Channel to Gibraltar, after having sent a branch running along the coast of Ireland and the coast of Norway as far as the North Cape. It then returns to the west, encircling the Canaries. Its center oscillates somewhere to the southwest of the Azores. The author's observations enabled him also to establish a very good average for the speed at which these floats traveled in the different sections of the vortex, and for every twenty-four hours: Between the Azores, France, Portugal, and the Canaries, it was 5.18 miles; from the Canaries to the Antilles, the Bahamas, Winds of the Sahara.—Some interesting meteorological observations, made in the Sahara during eight excursions between 1883 and 1896, have been published by M. F. Foureau. The most frequent winds are those from the northwest and the southeast. Every evening the wind goes down with the sun, or goes to bed, as the Chaambe express it; except the northeast wind, which the Arabs call el chitÂne, or the devil, because it blows all night. Another wind, called the chihithi, has been mentioned by all travelers, and is the subject of numerous legends. It is a warm wind from the southwest, charged with electricity, and often carrying fine sand and darkening the atmosphere. The compasses are much disturbed by it, because, it has been suggested, of a special condition produced upon thin glass covers by the friction caused by the rubbing of the fine wind-carried sand upon them; but it has been observed that the spare compasses show the same disturbed condition as soon as they are taken out of their boxes. The disturbance ceases when the glasses are moistened, and does not appear again till they have dried. Several hailstorms were noticed, the hailstones being usually about as large as peas, but larger in the heavier storms. M. Foureau, not having gone as far as the central heights, observed no snow in the Sahara, but was informed that snow falls in the winter on the tops of the Tassili des Azdjer, about five thousand feet above the sea. Similar observations have been made by other travelers, and falls of temperature to about 21° F. have been noticed. Very curious mirage phenomena were sometimes observed. Observations of fulgurites, or instances in which the sand had been vitrified by lightning strokes, were not infrequent. Evolution of Pleasure Gardens.—A lesson in the evolution of pleasure resorts is suggested in a book by Mr. Warwick Wroth on the London pleasure gardens. The history of these places has in some cases a strong family resemblance. They usually began as tea gardens, with a bowling green, tea and coffee, hot loaves, and milk "fresh from the cow," as their chief attractions. If the business prospered, other amusements were added, such as music and dancing, with perhaps the exhibition of a giant or a fat woman. Equestrian performances were given in the more important gardens. The manager of one of them kept on the grounds a fine collection of rattlesnakes, one having nineteen rattles and "seven young ones." "Sixteen hundred visitors were present at another one day in August, 1744, to hear honest 'Jo Baker' beat a trevally on his side-drum as he did before the great Duke of Marlborough at the bloody battle of Malplaquet. It was not unusual, moreover, for the owner of a successful tavern to discover on his premises a mineral spring, of which a favorable analysis was easily obtained"—although the spring might be really a bad one. The Spa of Hampstead Wells enjoyed a delightfully pure and invigorating air on the open heath, and had a tavern with coffee rooms, a bowling green, raffling shops, and a chapel, which offered visitors an advantage possessed by no other gardens in London, as a clergyman was always in attendance, and a couple on presenting a license could be married at once on the payment of five shillings. Mr. Wroth suggests that the license was sometimes dispensed with, and the fee, moreover, was remitted if the wedded pair gave a dinner in the gardens. A Library of Astronomical Photographs.—The appointment of Mrs. M. P. Fleming as curator of astronomical photographs in the Harvard Observatory is noteworthy because hers is the first woman's name to be placed along with the officers in the university catalogue. It is more so as a recognition of Mrs. Fleming's proved abilities in certain lines of astronomical work. The astrophotographic building is not used for the taking of photographs, but as a peculiar kind of library where the plates secured by the astronomers at Cambridge and Arequipa are preserved, arranged, and catalogued, as is done with books. The duties of the curator are like those of a librarian. But instead of books, of which many copies exist, each of the treasures in the photographic collection is unique and can not be duplicated. Prints Forest Planting on the Plains.—Mr. Charles A. Keffer, in a report to the Forestry Division on Experimental Tree Planting in the Plains, defines the forestless region of America as including all the States between the Mississippi River north of the Ozark Mountains and eastern Texas and the Rocky Mountains, together with the plateau west of the Rocky Mountains. The possibilities of forest growth in this vast area are yet to be proved. Roughly speaking, any species that thrive in the adjacent wooded region can be grown in Iowa, the Red River Valley of Minnesota and North Dakota, the Sioux Valley of South Dakota and the eastern counties of Nebraska, and in the more southern States. We know that difficulties of cultivation increase as one goes westward, but we can not say where the western limit of successful tree culture is. We can not even define the limits of successful agriculture in the plains, for with increased facilities for irrigation splendid crops are now produced where only a few years ago it was thought desert conditions would forever prevail. It is admitted that forest planting, as a financial investment, will probably be profitable on the plains only in a limited degree. Favorable sites may enable the profitable raising of fence posts and other specialized tree crops, but the growing of timber on a commercial scale can hardly be expected. A Siamese Geological Theory.—The east coast of Siam as far south as Champawn is characterized by wide bays, with detached masses of limestone set on steep-sided islands or high-peaked promontories with serrated ridges, the most conspicuous of which is Sam Roi Yawt, or the three hundred peaks. The relations of these various rock masses to one another, Mr. H. Warington Smyth observed, in an address to the Royal Geographical Society, have been long ago lucidly set forth by Siamese geologists, who are unanimously agreed on the subject. "It appears that one Mong Lai and his wife once inhabited the neighborhood (they were giants), and each promised their daughter in marriage, unknown to the other, to a different suitor. At last the day of the nuptials arrived, and Chao Lai and the Lord of Mieang Chin (China) both arrived to claim the bride. When the horrified father found how matters stood—having a regard for the value of a promise, which is not too common in the East—he cut his daughter in half, so that neither suitor should be disappointed. Chao Lai, in the meantime, on finding that he had a rival, committed suicide, and the peak of Chaolai is the remains of his body. The unfortunate bride is to be found in the islands off Sam Roi Yawt, the peaks of which are the remains of the gifts which were to be made to the holy man who was to solemnize the wedding; while Kaw Chang and Kaw King, on the east side of the gulf, are the elephant and buffalo cart in which the presents were brought." "The Hell of War."—The Cost of a National Crime and The Hell of War and its Penalties are the appropriate names which Edward Atkinson has given to two essays bearing upon the craze for expansion in which the nation has been abruptly plunged. In them an evil which has not yet received due attention, if any, is presented as sure to be inflicted upon us if the policy of militarism is persisted in. "How much increase of taxation," Mr. Atkinson asks, "are you willing to bear, and how many of your neighbors' sons are you ready to sacrifice by fever, malaria, and venereal disease, in order to extend the sovereignty of the United States over the West Indies and the Philippine Islands?" Another question is put to the missionary enthusiasts: "It may be well to ask all who are imbued with this missionary MINOR PARAGRAPHS.A new and very ingenious method of space telegraphy is discussed at length in an article by Karl Zickler in the Elektrotechnische Zeitschrift. It depends on a phenomenon discovered by Hertz in 1887, viz., the influence of certain short wave-length light rays upon electrical discharges. The ultra-violet waves, which are obstructed by glass but transmitted by quartz, are the most effective. The source of light is an arc lamp. The light is passed through a lens of rock crystal to the receiver. The receiver is a glass vessel partially exhausted of air, one end of which consists of a truly parallel plate of rock crystal. In front of the receiver there is a condensing lens of rock crystal, and within the exhausted chamber are the two electrodes, one of which is an inclined disk and the other a small ball. The electrodes are connected with the secondary portion of an induction coil, and when the ultra-violet rays fall upon the inclined disk and are reflected to the ball, a discharge will be produced which may be read either with a telephone or a coherer. The signals are sent by alternately interposing a plate of glass in front of the rays issuing from the transmitter and removing it therefrom. Herr Zickler has made many experiments to verify his conclusions and appears to have demonstrated the feasibility of his idea in practice. Mr. Dawson Williams has announced in Nature the discovery in many susceptible persons of a periodicity in the effects that follow a sting. The immediate result, he says, is a small flattened wheal, pale and surrounded by a zone of pink injection. This is attended by itching, but both wheal and itching are gone in less than an hour. About twenty-four hours later the part begins to itch again, and in a few minutes a hard, rounded, deep-red papule appears, and is quickly surrounded by an area of oedematous skin. The formication is intense, and in the affected area, while the ordinary sensations of touch are dulled, those of temperature and painful feelings are exaggerated. In two or three hours the itching diminishes and the oedema disappears, leaving a small, red papule, which itches but little. The phenomena recur, with diminished intensity, in the course of another twenty-four hours, and may return in this way, growing fainter all the time, in four or five daily repetitions. After these returns have ceased, a small, indolent papule may persist for weeks or months. This periodicity is not observed in all subjects, but most generally in those who suffer most. Among the advantages of Linde's liquid-air process, Prof. J. A. Ewing, speaking at the English Society of Arts, claimed its giving a means of separating more or less completely the oxygen of the atmosphere from its associated nitrogen. After describing a process by which a liquid consisting largely of oxygen may be produced, the author said that the most interesting application of the liquid which had hitherto been tried on a commercial scale was to make an explosive by mixing it with carbon. When liquid air, enriched by the evaporation of a large part of the nitrogen, was mixed with powdered charcoal, it formed an explosive comparable in power to dynamite, and which, like dynamite, could be made to go off violently by using a detonator. The chief advantage of the explosive was its cheapness, the cost being only that of liquefying the air. Even the fact that after a short time the mixture ceased to be capable of exploding might be urged as a recommendation, for if a detonator NOTES.According to the Tribune de GenÈve, twenty new hotels were opened in Switzerland in 1897, and twenty-five were enlarged, adding two thousand beds and making the whole number of beds about ninety thousand. The number of nights' lodgings furnished during the season is estimated at ten million. Supposing each guest to spend twelve francs a day, the total revenue from tourists would amount to one hundred and twenty million francs, or twenty four million dollars. Classifying the guests according to nationality, it is estimated that the Swiss constitute eighteen per cent of the whole, Germans thirty-four per cent, English sixteen per cent, French twelve per cent, Americans eight per cent, and those of other nations twelve per cent. A list of women astronomers, compiled by Herman S. Davis from Ribiere's Les Femmes dans la Science, contains as contemporary workers in the science the names of seventeen American women who have taken part in astronomical computations or are teachers of astronomy, and twelve who are working in the application of photography to astronomy. Of the women in the later list, Miss Ida C. Martin, Miss Dr. Dorothea Klumpke (now in the Paris Observatory), and Mrs. M. P. Fleming have attained distinction for successful original researches. The object of the Pure Food and Drug Congress, which met in Washington in March, 1898, with Joseph E. Blackburn, of Columbus, Ohio, as president, is declared in its resolutions to be to secure suitable national legislation to prevent the adulteration of food, drink, and drugs, to secure the enforcement of laws, and secure and promote uniformity of State legislation looking to that end; to create and maintain a high public sentiment on these subjects, to sustain public officers enforcing the laws respecting them; and to promote a more general intelligence concerning the injury to health and business interests resulting from food adulteration. In this work all are invited to join. The congress was in session four days, and several important papers were read to it. The large Atlantic coastal plain beginning with southern New Jersey, Mr. John Gifford affirms, in The Forester, would soon be capable, if protected from reckless devastation, of producing almost limitless quantities of the valuable smooth-bark or short leaf pine. In Northampton and Accomac Counties, Virginia, lying in this plain, the forests are already properly cared for and propagated without the aid of forest laws. This is done by insuring their freedom from fire, which is attended to purely as a matter of present economy. The value of the woods in holding the loose sandy soil and as windbreaks is recognized, and the litter of the pine trees is a precious dressing for the sweet potato fields. This litter, of pine "chats," "needles," or "browse," is carefully raked off every year and spread on the fields, and there is nothing left in which fire can start. The Lalande prize of the French Academy of Sciences has been conferred upon Prof. S. C. Chandler, of Cambridge, Mass., in recognition of "the splendor, the importance, and the variety" of his astronomical work; the Damoiseau prize upon Dr. George William Hill, of Washington, for his researches in mathematics and astronomy; and the Henry Wilde prize on Dr. Charles A. Schott, of Washington, for his researches in terrestrial magnetism. Prof. J. Mark Baldwin, of Princeton, author of the books The Development of the Child and the Race, Handbook of Psychology, and The Story of the Mind, has been elected a member of the French Institute of Sociology. Among the recent deaths of men associated with scientific pursuits we notice those of Charles Michel Brisse, professor at the LycÉe Condorcet for twenty-five years, and professor at other French schools, author of papers on the displacement of figures and on the general theory of surfaces, and of other works in mathematics and mathematical physics, and a co-worker on the Journal de Physique, in his fifty-sixth year; Prof. H. Alleyn Nicholson, of the University of Aberdeen, author of books on zoÖlogy and geology; M. F. Gay, of the University of Montpellier, a student of the green algÆ, aged forty years; Dr. Dumontpallier, of Paris, author of contributions to the pathology of the nervous system, aged seventy-four years; Lieutenant-Colonel Robert Pringle, of the British Army, author of papers on the hygiene and diseases of India; Pastor Christian Kaurin, of Norway, a student of Scandinavian mosses, aged sixty-six years; T. Carnel, professor of botany and director of the Botanic Garden, Florence; the Rev. Bartholomew Price, author of several elaborate works in mathematics, and secretary of the Oxford University Press, in his eighty-first year; Dr. Constantine Vousakis, professor of physiology in the University of Athens; William Dames, professor of geology and paleontology in the University of Berlin, and subeditor of the PalÄontologische Abhandlungen, in his fifty-second year; and Dr. Gottlieb Gluge, emeritus professor of physiology and anatomy in the University of Berlin and author of an atlas of pathological anatomy, aged eighty-six years. |
