46 INTR OD UCTION. 



Temporary memoranda may be made across the slip, but all other notes 

 should be written lengthwise, and preferably on one side only. 



97. Slip notes are of the following kinds: museum catalogues; library 

 catalogues ; references ; extracts ; clippings ; statements of observations or 

 ideas, original or otherwise, with or without drawings. 



98. Library Catalogues. The titles of books and papers should 

 comprise at least the following data : the author's name and surname or 

 initials ; the title and subtitle of the book or paper. With a book, the edi- 

 tion, size, number of pages and illustrations ; the place and date of publica- 

 tion. With a paper, the Periodical in which it was first published, dates of 

 presentation and publication, the volume, part, pages and illustrations. With 

 both, references to Translations and Abstracts. 



The foregoing data are entered in various orders, and with different kinds 

 of abbreviation. Those who desire to adopt some standard method of writ- 

 ing titles should consult the " Catalogue of Scientific Papers " published by 

 the Eoyal Society of London, the publications of " The American Library 

 Association," and the " List of Periodicals taken by the Public Libraries 

 near Boston." 



A. One of the valuable suggestions of the Library Association is that the more com- 

 mon given names should always be indicated by the initial, this initial being distinguished 

 from the same letters used elsewhere by a colon following : For example, E. might stand 

 for Edwin, Egbert, Edmund, etc., but E: would always signify Edward. 



B. Another suggestion, that the sizes of books should be indicated not by numbers 

 but by the initials of the words signified by the numbers, as O. for octavo, etc.. is carried 

 out in the " List " j ust mentioned, and is made more available by the use of the "Book 

 Size Rule," provided by the Readers and Writers Economy Company, being a metric 

 rule, 30 cm. (1 ft. ) long ; this is also a convenient desk rule. 



99. Catalogue Data. On the face of the Museum Catalogue Card 

 should be noted the following : Museum number, original number, class (of 

 animals), series (of specimens or preparations), genus, species, common name, 

 locality, sex, age, dates of collection, death, and reception (which do not 

 always coincide). This should leave the lower half of the face for a brief 

 description of the preparation ; purpose for which it was made ; reference to 

 any original list, to publications, etc. 



On the reverse of the slip should be, after a repetition of the museum 

 number : the original weight of the brain, and of the body, and the ratio in 

 decimals; the present (usually alcoholic) weight of the brain and body; the 

 capacity (of an inflated preparation); the length from vertex to anus (of an 

 entire example); by whom collected ; when and by whom prepared ; donor 

 or seller; his address; original cost, expressage, etc., hours' work; estimated 

 present value ; museum numbers of other specimens from the same indi- 

 vidual ; numbers of other preparations from members of the same litter ; 

 numbers of other specimens with which this may be instructively compared.
