The Committee are of opinion that the following range of sutyects 

 should be included in the scheme : — 



1. Portraits of any species of plant (more particularly foreign plants, 

 grown under natural conditions), illustrating habit, natural surroundings, 

 or points of morphological or physiological interest. 



2. Diseases and malformations of plants. 



3. Photographs of plants raised for purposes of experiment. 



4. Photographs illustrating plant associations. 



The Committee do not recommend at present the incUision of photo- 

 graphs of histological preparations, nor do they consider that it would 

 be desirable to include photographs of zoological interest in the same 

 register with those of botanical interest. 



APPENDIX 



Arrangements in existence for the Preservation and Registration of 

 Photograjihs of Anthropological and Geological Interest. 



Both the Anthropological and the Geological Section of the British 

 Association collect, preserve, and register prints of anthropological and 

 geological interest respectively. 



These are preserved, in the case of the geological photographs, in the 

 Jermyn Street Museum ; in the case of the anthropological photographs, 

 also at some central institution. 



The standard size for the geological photographs is whole plate, but 

 other sizes are accepted. They are mounted on cards of uniform size and 

 bound in albums. The anthropological photographs are mounted on cards 

 of two sizes and filed, like card catalogue slips. 



The photographs are arranged geographically, but a cross index of 

 topics is also prepared. The card catalogue of the collection gives all 

 necessary information as to locality, date, name of photographer, <fec. 



Negatives are either retained by the owner or deposited with a local 

 photographer, who will supply prints at reasonable prices. The anthropo- 

 logical section has also made arrangements for the storage and insurance 

 of any negatives deposited with them on loan. 



No arrangements are made as to copyright. A detailed list of photo- 

 graphs received is published every year with the annual reports of the 

 Committees, which states where the photographs may be obtained, and a 

 copy of this report is sent to each donor. 



Both Sections appoint Committees to carry out these schemes, and 

 each Committee receives a small grant.
