Page 107, weight of bullet, ·530 grains: as printed in the source document, but unlikely to be correct.
Page 114, paragraph on Parabolic theory: even with the corrections mentioned in the errata, some of the reference letters are missing; F, G and H are presumably the ends of the vertical lines through C, D and E respectively.
Page 119, strictly empirical formula: should probably have been a plural.
Changes made:
Footnotes have been moved to directly after the paragraph to which they refer.
Some minor obvious punctuation and typographical errors have been corrected silently.
B.C./B. C. and A.D./A. D. have been standardised to B. C. and A. D., respectively. Minie, Miniè (the spelling used most commonly in this book) and Minié have been standardised to Minié.
The (corrected, see below) Errata have already been applied to the text.
Errata: Page 32, para. 6, line 10 changed to Page 32, para.7, line 10; IX and XII changed to ix and xii; Page 84, para. 2, line 1 (2nd entry) changed to Page 84, para. 3, line 1. Subalterns changed to subaltern officers; Page 91, para. 5 changed to Page 91, para. 4; sign changed to sine.
