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 HUSS: "This appointment had a deep influence on the already
vigorous religious life of Huss himself ..." 'appointment' amended
from 'appoinment'.
ARTICLE HYACINTH: "... the wild hyacinth of western North America,
Camassia esculenta." 'America' amended from 'Amercia'.
ARTICLE HYDRAULICS: "Fig. 74 shows an arrangement designed for the

from Howden's statements 16.58 × 40/26 = 25.5 ft. per second, an
agreement as close as the approximate character of the data would
lead us to expect." Added 'per second'.
ARTICLE HYDRAULICS: "... as the velocity and area of cross section
are different in different states of the river." 'different'
amended from 'differest'.
ARTICLE HYDROGEN: "... for example, formic, glycollic, lactic,
tartaric, malic, benzoic and other organic acids are readily
oxidized in the presence of ferrous sulphate ..." 'glycollic'
