a case the year-numerals take the place of volume-numerals and the above 
would appear thus:—Alabama Agr. Exp. Sta. Rept. 1896:1-87. 
Number-numerals when indicating consecutively paged parts of a 
volume (as for example, vol. 27, No. 6 pp. 70-83) should not appear in 
the reference. When not paged consecutively the number-numeral 
appears between volume-numeral and page-numeral. 
Bulletins, circulars, memoirs, leaflets and the like are usually numbered 
and are not considered as constituting consecutively paged numbers of 
avolume. Thenumerals appear therefore in place of the volume-numerals, 
but are not to be underscored. The proper abbreviation for the word 
Bulletin is Bul. with a capital B. Where qualified, as for example, Techni- 
cal bulletin, it is abbreviated but not capitalized. 
Series, Abteilungen. If a periodical is issued in two or more separate 
series the series-numeral precedes the volume-numeral, separated from it 
by a colon and is not to be underscored, as:—3: 46: 23-87. Sometimes 
‘the series is indicated thus:—Science n. s. 42: 47-56. Then.s. = New 
Series. 
Parts. If parts of a volume are paged separately, the part-numeral 
follows the volume-numeral and is separated from it by a colon:—thus, 
82:2: 241-256. 
Pages. The page-numerals when preceded by volume- or number- 
numerals and a colon are to be cited inclusively, i.e. first and last pages 
separated by a dash thus:—17-83, and followed by a period. 
Tables, plates and figures follow directly after the pages, properly 
abbreviated, followed by the proper numerals in arabic. 
Year. This must be the actual year of publication. It may not 
always be determined with certainty except by consulting the original. 
Exercise care on this poit and leave the space blank until the original 
can beconsulted, if not absolutely sure of it from the reference. 
Books. In cases where no volume is given, cite the pages thus:—p. 27 
or p. 1-441. 
Citation from books. Following the date, give the title of the chapter 
or paragraph, especially referred to, then, J, then the title of the book 
followed by the letter p. to indicate page, then the page number and finally 
the date thus :— 
Ellis, J. B. Dothidea pomigena. Schw. In The North American 
Pyrenomycetes. p. 605. 1892. 
Government publications are alwavs to be cited in the following form;— 
U.S. Agr. Dept. Yearbook; or U.S. Plant Ind. Bur. Bul. 37: 
State Experiment Station publications are always to be cited thus:— 
Alabama Agr. Exp. Sta. Bul.; or New York (Geneva) Agr. Exp. Sta. 
Rept.; Cornell Univ. Agr. Exp. Sta. Bul. 237:46-91.
