136 PROCEEDINGS OF THE SOCIETY. 



Entomology, with particular reference to the Food of Insects." Unfor- 

 tunately — and he knew they would all regret it — Mr. Wesche was unable 

 to be with them, having been laid aside by severe illness. He had, however, 

 sent in his paper that afternoon, and a number of slides in illustration of 

 the subject to be exhibited under Microscopes in the room, whilst five 

 lantern slides were ready for the lantern to be shown upon the screen. 



Dr. Hebb having read some portions of the paper which had been 

 marked by the Author, 



The Chairman, in moving a vote of thanks to Mr. Wesche for this 

 communication, again expressed his regret at the enforced absence of its 

 Author, whose work was always so thorough that his papers were neces- 

 sarily long and rather difficult to epitomise, so that the one before them 

 would have to be read to be properly understood. The thanks of tin- 

 Meeting were also voted to Dr. Hebb for reading the extracts and to 

 Mr. Imboden for preparing the slides which had been shown on the 

 screen, as well as to Messrs. Baker for the loan of the Microscopes under 

 which the mounted preparations had been exhibited. 



Mr. J. E. Barnard's paper " On an improved type of Mercury Vapour 

 Lamp" was deferred to a future Meeting, as the Author was unable, to 

 be present in consequence of a severe cold.
