As soon as life ceases in animal matter, disorganization commences; the constituent elements separate, to be variously recombined, and to give birth to new compounds.

The elevation of atmospheric temperature in certain determined hygrometric limits, and the action of oxygen, are those circumstances which lead necessarily to this decomposition. But, at a given temperature, the progress of putrid fermentation is not the same for all animals; this varies among different species, and different individuals of similar species, according to laws not well determined. But so important, however, are these laws, to the art of embalming, that processes which are sufficient for the preservation of one body, may fail in their application to others.

The ancients had well observed, it is true, that the diversity of climates contributed much to the difference in mummies, and to the success of embalming; for, according to Camerarius, great difference exists between the bodies of Europeans and Orientals; the latter, of a dryer temperament, are not exposed to so rapid a decomposition. The example related by Ammian Marcellini is a convincing proof. Four days, says he, after a combat between the Persians and Romans, the countenance of the latter could scarcely be recognised; the bodies of the Persians, on the contrary, were dry, without humidity, without sanies, and without any alteration.

If sufficient attention is given to this fact, and we consider further, that the thermometrical and hygrometrical conditions of the atmosphere were such in Egypt, that the bodies abandoned to themselves, become dried and formed natural mummies, we shall perceive how vain and unreasonable have been the attempts of those who, for a long series of ages, expected in the middle and northern portions of Europe to embalm human bodies by processes which are only an imperfect imitation of those of Egypt, even in what is defective. Finally, we shall understand how it happens that the sepulchres of the Guanches and Egyptians, yield bodies in such a perfect state of preservation, whilst those of our country offer only bones and dust.

Whilst according to the Egyptians the just tribute of admiration which their profound wisdom and extensive acquirements merit, we ought, in a scientific question, to defend ourselves from the infatuation of our predecessors, which led them into error, and appreciate at their just value facts badly observed.

We read in the letters of M. de Maillet, “the dry and nitrous earth of Egypt has the property of naturally preserving entire bodies without the aid of any art, especially in those countries at a distance from the Nile. This is a fact which experience does not permit us to doubt. Not long since, there were buried some Frenchmen, in a Coptic church which is in old Cairo, and those who descended the cavern found the bodies of others who had been previously deposited for some time, as perfect as they were the very day that they were inhumed: The clothes even of a Venetian consul, whose corpse had been here interred, were perfectly preserved. I have likewise visited several ancient Mosques, formerly celebrated, but now in ruins, which are situated on the road from Cairo to Suez; these edifices have served as tombs to some Mahommedan kings, whose bodies were here deposited, during the period when Egypt was subject to the Arabs. I investigated some of these caverns, and can assert that I observed bodies so light from desiccation that they could be raised with one hand as easily as if they were a walking stick. Among these bodies, was one which weighed less than four pounds; I saw also a thigh, which, although it appeared entire and full of flesh, with the leg and foot attached, did not weigh one pound. Finally, the same thing is daily observed by the caravans which go to Mecca. There are none of these wanderers who have made this voyage, who could not testify that the bodies of those who die on the route, are dried to such a degree as to become as light as straw.”

If, then, we would wish to judge a priori of the relative value of the processes of embalming, followed by the people of Asia and Africa, and of those employed by European nations, we ought to start from this double fact—that among the first, bodies abandoned to themselves have a tendency to dry and mummify, both on account of the small quantity of fluid they contain, and on account of atmospheric influences; whilst those of the second, rot and dissolve under the influence of contrary causes.

We think then, with M. Rouyer, member of the Egyptian commission, that the most efficacious cause of the perfection of the art of embalming of the Egyptians, and of the wonderful preservation of the mummies, was the climate of Egypt, and chiefly that elevated and equal temperature (20°R.) which exists in the interior of sepulchral chambers, and in all subterranean places specially consecrated to sepulchres. A fact which ought to be joined to this last, has been proved by MM. Docts. Boucherie, Bermont, and Gaubert, during a visit to the caves of St. Michel at Bordeaux. These caverns which contain seventy bodies, taken from the neighbouring sepulchres forty years ago, and mummified by causes of which we shall speak in the sequel, are of a temperature of eighteen degrees.

In order to terminate this discussion by a fact universally known, the mummies preserved untouched for several thousand years in the caverns of Egypt, become altered and destroyed very rapidly, when transported into Europe, and divested of their bandages, they are exposed to the influence of our atmosphere.[C]

These various observations convince me that a precise knowledge of the art of embalming among the ancients, would not suffice to preserve bodies in our country; and what we do know, decides me to push my researches in another direction.[D]

Besides, the methods for embalming have varied with time, place, and circumstances. The Ethiopians, inhabiting a country which furnishes in itself more gum than all the rest of the world, conceived the idea of enclosing the body in a melted mass of this transparent matter, and thus to preserve them like insects enveloped in fluid amber, and which are found uninjured and very visible in the middle of this substance when solidified. This mode of preservation has led some to suppose, that the Ethiopians preserved their dead bodies in glass. Honey was formerly used for embalming; the body of Alexander the Great was rubbed with honey, as the following verses prove:

“Duc et ad Æmathios manes, ubi belliger urbis
Conditor hiblÆo perfusus nectare durat.”

This use of honey is further confirmed by J.B. Baricel, AndrÉ Rivin, and R.P. MÈnestrier. Pliny, book xxii. chap.24, says that honey is of such a nature, that bodies placed in it do not corrupt.

They made use also of wax for embalming, as we read in Emilius Probus, at the end of the life of AgÉsilas: “Having fallen sick, he died, and that his friends might the more conveniently carry him to Sparta, for want of honey they enveloped his body in wax.” The Persians, on the report of Cicero, employed the same matter: PersÆ jam cerÀ circumlitos condiunt, ut quam maximÈ permaneant diuturna corpora.

The ancients also made use of a sort of brine, the composition of which is unknown. Coelius Rodiginus, in his book of antiquities, remarks that, during the pontificat of Sextus IV. they found on the Appien way the body of a girl, retaining still all the beauty of her face, the hair of a golden blond, and tied up with bands, also gilded—it was thus preserved in a brine, which entirely covered it, and it was thought to be the body of Tulliola, the daughter of Cicero. And Valateron assures us that, by a preparation of an unknown salt, the body of another female was also found entire in a mausoleum near Albania, in the time of Alexander VI.; this Pope ordered it to be thrown secretly into the Tiber, fearing the superstition of the people, who run from all parts to see it, because the body still retained its beauty, although thirteen centuries had elapsed since its deposition.

The Jews, after closing the mouth and eyes of the dead, shaved them, washed and rubbed them with perfumes, then enclosed them in a coffin along with myrrh, aloes, and other aromatics, in great profusion.

The Egyptians had a great number of processes for embalming. The valuable work of M. Rouyer places this fact beyond a doubt: natron, cedria, bitumen, asphaltum, pisasphaltum, different aromatic substances to drive off insects, varnishes, more or less costly, were used in their different preparations; finally, bandages multiplied, and endued with gum Arabic, closed all access to air and humidity. The mummies of the Guanches, which so closely resemble some of those of Egypt, were sewn up in skins, after having been stuffed with aromatics and dried in the sun.

The moderns have employed for the preservation of dead bodies, numerous substances both fluid and solid; spirits of wine, oils, tinctures, compound liniments, brines, etc., constitute the first class; powders, composed of all parts of balsamic and aromatic plants, form the second.

We shall examine, hereafter, more in detail these various systems of preservation—nevertheless, what we have mentioned, proves that they were only in a slight degree efficacious. And even the so much boasted methods of Clauderus, Derasieres, &c., and the wonderful secrets of Debils, Ruysh, Swammerdam, appear to us only applicable to retard a little while the progress of decomposition. The following is extracted from the article Anatomical Preparations of the Dictionary of Medical Sciences:

“It is said that Ruysh possessed the means of preserving the flexibility and other vital properties of the different tissues of our bodies. When the Dutch anatomist sold his cabinet to the Czar, Peter I., he gave a manuscript in which he made known the composition of a preservative fluid, expressly stating that this liquor was nothing more than spirits of wine; the spirit of malt, to which was only added, during distillation, a handful of white pepper. But it appeared that Ruysh had not given the true composition of his liquor, or rather, that he had exaggerated the virtues of it, for it is far from possessing the effects which have been attributed to it. After the death of Ruysh, they thought they had discovered his means of preserving. In 1731, Geoffroy was charged to make experiments; but the results did not correspond to the anticipations.”

We find in a note added by Strader, at the end of his edition of the works of Harvey, another version relative to the proceedings of Swammerdam, which is as follows:

“It is with reason,” says he, “that we prefer to the Egyptian method, an art which so hardens dead bodies, that they lose nothing of their substance, and change neither in colour, nor in form; that they leave to the anatomist all desirable leisure for examination, without presenting any effusion of blood, nor that disgusting filth so repugnant to the delicate practitioner, and which frequently prevents the examination of the entrails of subjects.

“I shall publish, as was communicated to me, this admirable process, in which I was formerly liberally initiated by Cl. Dn. Swammerdam, which is beyond all praise. It is necessary, then, to obtain a pewter vessel of sufficient size to contain the body to be embalmed; place at the distance of about two fingers depth of the bottom, a hurdle of wood, pierced with many holes; place the body on this hurdle, and pour on oil of turpentine to the height of three fingers, keep the vessel quiet, tightly, and less and less hermetically covered during a certain space of time; in this manner the oil, of a penetrating nature, will infiltrate by degrees into the body on which it is poured, and will expel the aqueous portions, the principal cause of the fermentation which tends to corruption. This aqueous portion descending by its specific gravity, and distilling through the flesh, will, in time, occupy the space between this and the bottom, and during this time the more subtle part of the balm will exhale, as the vessel is less closely covered; the more it evaporates, the harder the body becomes, and will imbibe the thick lees of the oil, the effect of which may be compared to that of a gummy marrow: it can then, consequently, remain out of the liquor and in open air without corrupting, without any fear of putrefaction, or of the worms. As to the time necessary to allow the body to remain in the balm, this varies according to the nature of the subject to be preserved. The following rules on this head must be observed:

“The embalming of an embryon of six months, may be accomplished in about the same length of time.

“The skeleton of the same embryon requires only about two months.

“The membranes of the heart, three months.

“The vessels of the liver, and of the placenta, cleared of their flesh, one month.

“The vessels of the spleen, ten days.

“The intestines, one month.

“A certain time is thus assigned for other vessels, which would not be difficult to discover or determine by experiments.

“It is always necessary to pay attention, that during this operation, the parts be a little contracted and compressed in an equable and convenient proportion; the coction of the body prevents the skin forming wrinkles, whether it be made before the deposition in the oil, or after it has soaked there for two months. In order that the subject may retain all its beauty and whiteness, it must be macerated for several days in alum before embalming it. In order that the members may retain a convenient form and position, they ought to be plunged into the balm on the commencement of winter, about the month of November, to expose them afterwards to the cold, not to freeze, but to harden them lightly.

“In following this process, with care, we destroy entirely all the germs of putrefaction concealed in the body, to such a degree, that the entrails even are profoundly penetrated with this balm, and are able to resist the constant attacks of the air.

“If it is desired to preserve a part, without the process above mentioned, the blood must first be extracted by a brine, and the salt subsequently withdrawn by rain water, and, after having placed it in the shade to prevent its putrefying, endue it with a mixture composed of three quarts of oil of turpentine, and one quart of mastic, which will communicate a brilliant appearance to it, and even a sort of light crust, particularly if a greater quantity of mastic is used in the preparation.

“As regards the preparation of the members and their appendages, a particular process must be observed. The vessels must be well dried, of whatever matter they may consist, and afterwards place the rods in them well fitted to the cavity; and previously endued with suet, which is to be carefully withdrawn in a few days; thus the members, large and small, ought to be placed in cotton, well soaked in suet, to be stretched in the direction of their length, as, for example, we stretch the meshes of capillary vessels on sticks rubbed with suet, from whence they are readily detached by means of a little fire placed beneath, which causes the suet to melt.

“But sufficient has been said for the present; perhaps, hereafter I shall have a more favourable opportunity to relate other similar facts, or even more admirable; for I have seen with Swammerdam, of whom I have spoken above, various pieces embalmed with so much talent, that, besides all their natural properties, they possessed also that of being always soft and flexible; I must forbear transmitting for the present this process, in order not to lessen the Èclat of the fine work I have just described, and in introducing a still more beautiful one on the scene, etc.”

After so precise a description, I hoped to make something out of this process; but nevertheless, I must confess, that after having repeated these experiments with the greatest care, I was no more successful in my trials than Mr. Geoffroy was in 1731; only I have proved that, when bodies are prepared according to my process, and afterwards plunged into turpentine, they preserve a remarkable freshness and suppleness. After much reflection upon this subject, I have come to the conclusion, that Ruysh and Swammerdam have never made known but a part of their system of preservations, and that, previously to immersing the body in either of the two liquids of which we have spoken, they subjected them to some preparation. In fine, those very authors who boast of the admirable perfection of their processes, have not left a single preparation to show as an example to justify their praises; and, as a proof of their exaggeration, we have the testimony of an author (Penicher) profoundly versed in this matter. “Those authors,” says he, “who boast of having embalmed without emptying the great cavities, and by confining themselves to injections by the mouth, by the anus, or by holes made in the armpits, would be embarrassed to show satisfactory results from such superficial embalming; for, sooner or later, these nuisances will overcome all the embalmer’s industry, and all the expense he may have been at to conquer a bad impression. Could there exist a more singular proof of this, than what happened a few years ago in the church of R.R.P.P., respecting the body of a lady of first quality? The corpse had been placed in a leaden coffin, and enclosed in another of wood, and placed within a marble mausoleum well cemented; after which, in order to fulfil the will, it was embalmed, and enveloped in two hundred pounds of aromatics and perfumes; two kegs of aromatic spirits of wine were introduced through an opening, so that the body was completely submerged in it. Nevertheless, at the end of twelve years or thereabout, it produced so dangerous and malignant a stench through the cracks which occurred in the coffin, by the expansion of the drugs, that one of the priests, who chanced at the time to be saying mass in his chapel, fell extremely ill from this cause, and the assistants were obliged to withdraw, being unable to support the effluvia.

“The priests were under the necessity of exhuming the body, with the consent of the archbishop, and family of the deceased; they removed it to the garden, placed it in a ditch, and covered it with quick-lime, which not destroying the flesh, composed of oily, sulphurous, and resinous parts, it was found necessary to remove the flesh from the body, in order to replace the skeleton in the mausoleum; to such a degree did the bad qualities of the entrails and viscera, corrupted by disease, surpass the good qualities of the balms.”

The imperfections of these methods grow out of their very nature. Along side of these embalmings, practised in an empyrical manner, without any reference to the qualities more or less efficacious, of the aromatic and balsamic substances, I can place infants several months old, subjects most susceptible of dissolution, and which, after a simple injection, have remained exposed to the air in a moist room. At the end of two years of this exposure, they displayed a great suppleness of the tissues, without the least trace of decomposition. Those which I enclosed in cases, in the midst of an atmosphere of my own discovery,[E] have preserved exactly the expression and colour of the face, that they had at the moment of death.
