INTRODUCTION 



Direct Quotations from Books. The 

 author's name, date, and page only are 

 used, thus: 



DS 11.123 Anderson Anderson 1929, 129 



At the end of Part II there is a list of 

 books cited where "Anderson 1929" is ex- 

 panded to a full bibliographic reference. 



Indirect Quotations from Books. It 

 too frequently happens that a book quotes 

 a formula by name, either without giving 

 a reference at all or with an incorrect 

 reference. When the present author has 

 been unable to find the original he uses the 

 abbreviation test. Thus: 



DS 11.123. Conklin test. 1930 Guyer Guyer 

 1930, 232. 



This indicates that the volume in ques- 

 tion contains, on page 232, a formula for 

 Conklin's picro-hematoxylin but offers no 

 information as to where the original can 

 be checked. 



Where the author of a book cited is 

 quoting at second hand, the abbreviation 

 cit. is used. Thus 



DS 11.24 Vignal test. 1907 Bohm and Oppel 

 cit. Henneguy Bohm and Oppel 1907, 

 118 



indicates that, on page 118 of the volume 

 in question, there is a statement to the 

 effect that Henneguy proposed, following 

 the method of Vignal, to prepare a picro- 

 carmine by this particular method. 



Where the author of a book cites him- 

 self, or the authors cite themselves, with- 

 out reference, the abbreviation used is 

 test. ips. (standing for teste ipso or testihus 

 ipsis). Thus: 



MS 31.22 Cajal 1925 test. 1933 ips. Cajal 

 and de Castro 1933, 262 



The present author would plead in self 

 defense that he has tracked more than a 

 thousand such references to the originals 

 and that these test, and cit. references are 

 used only where he has failed to find the 

 original or where the original is incorrectly 

 quoted. 



Direct Quotations from Journals. 

 The author has used, in place of the name 

 of the journal, the number assigned to that 

 journal in the World List of Scientific 



Periodicals (Oxford, The University Press, 

 1927). Thus: 



DS 11.122 Carazzi 1911 23632, 28:273 



indicates that Carazzi's formula is given 

 on page 273 of volume 28 of the Zeitschrift 

 far wissenschdftUche Mikroskopie und fiir 

 mikroskopische Technik. The full titles of 

 the two-hundred-odd journals cited will 

 be found immediately preceding the index. 

 The use of this number not only saves 

 space, an important consideration in a 

 volume of this magnitude, but also permits 

 exact identification of the journal. The 

 author decided to use these numbers quite 

 shortly after he started checking refer- 

 ences in the /. Anat. (either of two jour- 

 nals) and the /. Bot. (any one of three 

 journals). 



Indirect Quotations from Journals. 

 The abbreviations test., test. cit. and test, 

 ips. are used with journal references ex- 

 actly as described for book references. 



Unpublished Information. The ab- 

 breviations in verb, and in litt. indicate 

 that the author has received unpubhshed 

 information either verbally or in a letter. 

 Thus: 



V 12.2 Fant 1932 in verb. 



indicates that Mr. Fant told the author 

 the unpubhshed composition of his seahng 

 medium for glycerol mounts in 1932. 



.Slavonic Names 



Where the author has cited Slavonic 

 names from a Cyrillic alphabet original, 

 he has transliterated according to the 

 rules of the Library of Congress (Beetle, 

 Clara, ed. A. L. A. Cataloging Rules for 

 Author and Title Entries. Chicago, Ameri- 

 can Library Association, 1949, p. 246) 

 without regard for the writer's preference 

 as indicated in, say, a German summary 

 of his paper. Thus Yasvoyn, not Jasswoin, 

 is cited from the original. Slavonic names 

 cited from a Latin alphabet original are 

 transcribed directly even though this in- 

 volves referring to the same individual by 

 several names. Slavonic names cited at 

 second hand are also transcribed directly, 

 no matter how obviously they may have 

 been mistransliterated.
