(h) The first and last page of the communication united by a 

 hyphen and enclosed within round bi-ackets ( ). If there 

 are plates, &c., this is to be stated as above, A (/<). 



(i) The Registraticn number or numbers within square brackets 

 (w. 62 and 63). 



Subject Catalogue. 



60. It was decided, at the Conference of June, 1900 : — 

 " That, in indexing- according- to subject-matter, regard shall 

 be had, not only to the title (of a paper or book), but also to the 

 nature of its contents," and also that " Lists of species must be 

 reckoned according to the space occupied, as may be arranged 

 by the Central Bureau." 



Latitude is given to the Reg-ional Bureaus as to the extent to 

 which they will index papers according to their contents, and 

 supply a greater number than an average of two slips for the 

 Subject Catalogue. In all cases these extra entries should be as 

 brief and concise as possible, and their relative importance should 

 be indicated on the slip as stated below (see Section 63). 



6L It is hoped that, a.s- an average, not more than three slips 

 will be sent in for each book or paper, viz., one for the Authors' 

 Index, and two for the Subject (Jatalogue. 



62. On the slip which is to be used for the Subject Catalogue, 

 the Registration Letter, written in the top left-hand corner of 

 the slip, is to be immediately followed by the Registration 

 Number or symbol, according to the Schedules, indicating the 

 sub-division of the science under which the material referred to 

 is to be catalogued. 



63. When it is desired that the entries for a book or paper should 

 be entered under several heading.s in the Subject Catalogue, a 

 separate slip must be written for each heading. 



Since it may be impossible to find room for all these entries, 

 they are to be numbered 1, 2, 3, &c., in order of importance, these 

 numbers (1, 2, 3, &c.) being placed within roimd brackets ( ), 

 e.g., (1), (2), (3), &c., immediately beneath the Registration 

 number. Where space cannot be found in the Catalogue to 

 insert the title luider all the headings, the title will be inserted 

 under (1), and, if space can be found to insert it twice, under 

 (2) also ; if it can be inserted three times, it will appear under 

 (1), (2), arid (3), and so on. 



This procedure is to be adopted whether the entry is desired 

 to be repeated in the same volume of the Catalogue or to appear 

 in the Catalogues of more than one science.
