90 PROCEEDINGS OF THE SOCIETY. 



In proposing a vote of thanks to Mr. Cocking for his exhibit, 

 the President said he did not claim any special knowledge of the action 

 of dyes when employed in microscopical preparations. The necessary 

 tests must be made by those who were accustomed to that class of work. 

 It did not by any means follow that the purest dyes were the most 

 efficient. It was not so much a question of producing the purest dye as 

 of finding a dye, even if it contained a particular impurity, that was 

 most suitable for microscopical work. 



The vote of thanks was carried unanimously. 



Mr. H. Taverner exhil^ited Photomicrographs of Water Mites by the 

 Sangster-Sheppard process. 



Mr. Taverner was heartily thanked for his exhibit. 



The President then delivered his Presidential Address, entitled 

 " The Limitations of Microscopy." 



Prof. Cheshire moved : " That the best thanks of this meeting be 

 accorded to Mr. Barnard for his Presidential Address, and that he 

 be asked to allow it to be printed in the Journal of the Society." 



Lieut. -Col. Clibborn seconded the proposal, which was supported by 

 Dr. J. Rudd Leeson, and carried by acclamation. 



The President thanked the meeting, and said he would regard it as 

 an honour to have the address printed in the Journal. 



The President announced that the next meeting of the Society 

 would be held on March 19, and of the Biological Section on March 5, 

 when Mr. F. Martin Duncan would make^a communication, " Notes on 

 some Marine Crustacea."
