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) The following typographical error has been corrected:
ARTICLE ARACHNIDA: "The coxal glands do not establish any special
connexion between Limulus and Scorpio, since they also occur in the
same somite in the lower Crustacea...." 'they' amended from 'thay'.
