  • — distortion of … Original spelling and grammar have been generally retained, with some exceptions noted below.

    Original printed page numbers are shown in the right margin like "p052".

    Original small capitals LOOK LIKE THIS.

    Footnotes have been renumbered and moved from the ends of pages to the ends of the appropriate sections, which are: Advertisement (page iii); Part I; and Part II, up to just ahead of the Data Sheets—which have their own footnotes, which were neither moved nor renumbered.

    Illustrations are moved from inside paragraphs to between paragraphs. The symbol "lgr", in a caption to an illustration, links to a larger image—these are available only in the html edition. The transcriber created the cover image by editing the title page image, and hereby assigns it to the public domain.

    Pages 1618. Page 16 ended after "with another one, No. 31, also shown" (i.e. in the middle of a sentence). This was followed by Plates 14, & then by page 17, which contained two data tables, & then page 18, which continued the original paragraph. The transcriber has closed the paragraph, and moved the Plates and tables to follow it.

    Pages 3132. The footnote on page 31 said only "See footnote on page 32." The footnote on page 32 had no anchor in the text. Therefore, to simplify, the page 31 footnote has been eliminated, and its anchor is linked directly to the page 32 footnote. Pages 4647. The footnote on page 47 had no anchor in the text. However, the footnote on page 46 said only "See Footnote page 47". Therefore, the footnote anchor on page 46 has been linked directly to the footnote on page 47, eliminating the page 46 footnote.

    Page 63. The large table was split into two tables, repeating the first column in each part.

    Page 140. The paragraph for June 23 originally ended "dotted line in Plate". The transcriber has inserted " 34.", as a guess.

    Pages 190192. The wide tables were split into two, repeating the first column in each part.

    Page 193. The wide tables were transposed, row for column.

    Page 201. The wide table was split into two.

    Pages 297308, Data Sheets. Remarks originally situated in the tables are appended below each Data Sheet. The units of measurement were originally spelled out—m.= Metres; ft.= Feet; gr.= Grammes; and lbs.= Pounds. In the footnotes to the Data Sheets, in the phrases "curved wings 2-5 the way", and "rear wings have 2-3 of the efficiency", the hyphen seems to mean division, like "/". This usage occurs also in the caption to Plate 85, in "SCALE 1 1-16 INCH TO STATUTE MILE".

    Page 299. Item 41, "7 75" changed to "7.75".

    INDEX. The original index was structured in a way not suitable for this ebook. The white space on the printed page substituted for words not repeated. Thus, under "Balancing of aerodrome, … ", were indented entries for "engine", "wings and rudder", &c. This spacing has been rendered herein as a horizontal bar "—", one for each word to be understood as repeated. So in this case, two bars, meaning "Balancing of". Moreover, page numbers referenced by index entries were right-justified and preceded by dotted leaders. Herein, the leaders have been suggested by horizontal ellipsis "…".

    Estimating from Internet Archive's stated scanning rate of 400 ppi, the pages were about 6.2 by 9.2 inches. Body text was printed in 9 point type, with 3 point leading, and footnotes were printed in 5.4 point type.

    The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

    While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

    International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.
