Sixty-two Slides of Entomological Subjects Mr. J. Dehy. 



The President said that some time ago an alteration was made in the 

 bye-laws, under which 100 Presidents of other Scientific Societies were 

 eligible for election as ex-officio Fellows, and 78 Presidents were so elected. 

 It seemed, however, that the Presidents of the Eoyal Society, the Linnean 

 Society, the Eoyal Society of Edinburgh, and the Eoyal Irish Academy 

 had not been included, probably because the eminence of these Societies 

 would cause it to be assumed that their Presidents would be elected as 

 a matter of course. The meeting now, no doubt, would be pleased to agree 

 that the Presidents he had mentioned should be added to the list. 



This was agreed to unanimously. 



Mr. Crisp called attention, amongst the donations, to Dr. Crookshank's 

 new work on the Photography of Bacteria ; also to a number of slides of 

 hair which Dr. Ondaatje, of Ceylon, had forwarded to the Society with a 

 request for information as to its peculiarities of structure. If any Fellow 

 would take the slides for examination and report to the next meeting, they 

 would be glad to lend them for the purpose. Attention was also called to 

 the intended re-delivery by the President on the 16th instant of the lecture 

 which he gave with such success at the meeting of the British Association 

 in Canada. 



Mr. Deby presented 62 slides, chiefly of micro-hymenoptera, which 

 came from the collection of the late Mr. Frederick Smith. There was also 

 amongst them a complete series of slides illustrative of the development 

 of the larva of a Pediculus from its first coming out of the egg to its 

 mature condition. 



Prof. Bell said that the late Mr. Frederick Smith was so careful an 

 observer and collector as well as so skilful a mounter, that he felt sure that 

 the present they had received was even of greater value than perhaps could 

 be gathered from what Mr. Deby had said about it. 



The President thought that the best thanks of the Society were duo to 

 Mr. Deby for his valuable donation, and a vote of thanks to him was 

 unanimously carried. 



Mr. J. Mayall, jun., said that he took it for granted the Fellows were 

 interested in whatever concerned the history of the Microscope, and would 

 therefore be glad to know of any new facts which tended to throw light 

 upon the subject. They were told by some of the best authorities that 

 the notes by Eoger Bacon could hardly be considered as demonstrating 

 that he had a practical knowledge of the use of magnifying lenses, and 

 that his claim to be the inventor of them must be set aside. Fracastoro,
