Transcriber's Note: Italics are delimited by underscores; bold by equal
signs. Four occurrences of the oe-ligature in the word man[oe]uver
are left as [oe]. The four footnotes have been moved to the end of the
book. A few words were judged to be printer errors and were changed.
These include two occurrences of horse-power in the unhyphenated form,
the spelling of Tabuteau as Tabuteaw on p. 162, and the spelling of
hélicoptère as helicoptéré on p.208. On a few of the
figure captions, missing accents were added to some French names.
