Transcriber's notes:
(1) Numbers following letters (without space) like C2 were originally
printed in subscript. Letter subscripts are preceded by an
underscore, like C_n.
(2) Characters following a carat (^) were printed in superscript.
(3) Side-notes were relocated to function as titles of their respective
paragraphs.
(4) Macrons and breves above letters and dots below letters were not
inserted.
(5) [root] stands for the root symbol; [alpha], [beta], etc. for greek
letters.
(6) The following typographical errors have been corrected:
ARTICLE HYDROMECHANICS: "... and [omega] the angular velocity
about it generated by an impulse couple M, and M' is the couple
required to set the surrounding medium in motion ..." 'impulse'
amended from 'impluse'.
ARTICLE HYMENOPTERA: "... see P. Cameron's British Phytophagous
Hymenoptera (4 vols., London, Roy. Soc., 1882-1893)." 'Roy'
amended from 'Ray'.
ARTICLE HYRCANUS: "During its later years his reign was much
disturbed, however, by the contentions for ascendancy which arose
between the Pharisees and Sadducees, the two rival sects or
parties which then for the first time (under those names at least)
came into prominence." 'disturbed' amended from 'distrubed'.
ARTICLE ICELAND: "Iceland is emphatically a land of proverbs,
while of folk-tales, those other keys to the people's heart, there
is plentiful store." 'people's' amended from 'poeple's'.
