The abbreviations “fig.,” “pi.,” and “p.,” for figures, plates, and 
pages, respectively, are used regardless of the language of the title 
of the book or periodical; but the language of the title should be followed 
for edition, volume, and part. (See example A.) 
Citations under “Literature cited” should be placed in alphabetical 
order (or chronological, if desired) and, preferably, should be numbered 
for convenient reference. The reference in the text should be made as 
follows: “Was reported by Cugini (i, p. 75), etc.”; or “was reported 
by Cugini (1891, p. 75), etc.” 
Footnotes should be inserted in the manuscript on the line imme¬ 
diately following the reference and should be cut Off from the text proper 
by a line above and below. If desired, the specific page cited may be 
given. (See example D.) The reference in the text should be made as 
follows: “Cugini 1 said that, etc.” 
In Citations op books, the author’s surname, followed by his fore¬ 
name or initials, the verbatim title of the work, edition, volume, pages, 
figures, plates, and place of publication should be given. (See example B.) 
In footnote references the date should follow the place of publication. 
(See example D.) 
In Citations op periodicals the author’s surname, followed by his 
forename or initials, and the verbatim title of the article should be given. 
In should precede the title of the periodical, which should be followed 
by the number of the series, volume, and part, the inclusive pages, the 
number of figures, if numbered (if unnumbered, use “illus.”), and the 
number of plates. In footnote references the date should be placed at 
the end of the citation. (See example C.) The month and year should 
be given if there is no part number, but not in addition to the part num¬ 
ber, unless it is especially desirable. Where two dates are given, the 
nominal date should appear immediately after the volume number. 
Titles of periodicals are abbreviated according to the “List of Abbrevia¬ 
tions Employed in Experiment Station Record,” but for convenience 
they may be written in full in the manuscript. 
In Synonomy the author’s name and the title of the book or periodical 
should be abbreviated, and the date of publication written immediately 
after the author’s name. The place of publication should be omitted.
