256 PROCEEDINGS OF THE SOCIETY. 



our own frontier and the barren wastes of Thibet. He thought it was 

 very good work to get this record of species so curiously resembling our 

 own. Most of them were very small and inconspicuous, and it was 

 rather curious also to notice that most of the tropical species were, on 

 the average, smaller than those found in more temperate climates. 



The thanks of the Society were unanimously voted to Mr. Pearce for 

 his paper. 



Mr. E. M. Nelson's paper on " The Limits of Resolving Power for 

 the Microscope and Telescope," was taken as read. 



The Chairman said this paper would be printed in the Journal, and 

 they felt assured that the results arrived at by Mr. Nelson would prove 

 very interesting on careful perusal, although perhaps rather too technical 

 to be usefully read at a Meeting. 



The thanks of the Society were unanimously voted to Mr. Nelson 

 for this communication, and a further vote of thanks to Mr. Pillischer 

 for the loan of a number of Microscopes, was proposed by the Chairman 

 and unanimously carried.
