the memberg in appropriate and hu-

An invitation from Moses W. 

 Field, Esq., for an excursion to Wy- 

 andotte on the steamer Grace Mc- 

 Millan was accepted with thanks. 



After some merely business pro- 

 ceedings, the Society adjourned until 

 2.30 p. M. 



At the afternoon session there 

 was a much larger attendance, with 

 a fair sprinkling of ladies in the 

 audience, which included also 

 many prominent members of the 

 medical fraternity of the city. 



The first paper was read by Geo. 

 E. Fell, of Buffalo, who gave a 

 description of a series of plates, con- 

 sisting of enlarged, sectional draw- 

 ings, exhibiting the structure of a 

 human molar tooth. These plates 

 were beautifully and appropriately 

 colored and were so arranged as to 

 infold, thus exhibiting the structure 

 progressively by the successive un- 



folding of the plates. This paper 

 was received with great interest and 

 attention, but on account of the 

 numerous references to the plates 

 it cannot be given even in a con- 

 densed form without them. 



Prof. D. S. Kellicott of Buffalo, 

 then read a paper describing a new 

 species of fish parasite found U23on 

 the bull-head, and to which he gave 

 the name of Lerneocera tortua. 

 Only one specimen was discovered 

 which was on exhibition, beautifully 

 mounted. The parasite occurs 

 buried in a tumor caused by its own 

 presence just back of the pectoral 

 fin. Like others of its class this 

 parasite survives removal for a 

 considerable time. The scientific 

 description of the parasite was illus- 

 trated by woodcuts distributed to 

 the audience by which it was readily 

 comprehended. 



W. G. Lapham of Northville, 

 Mich., next read a somewhat lengthy 

 paper entitled " The Relation of 

 Medium Power Objectives to Micro- 

 biology, " in which he gave an 

 account of the use of different ob- 

 jectives, particularly a yV? ^^^ such 

 work. The writer considered the 

 subject very thoroughly, and drew 

 the conclusion that with a -^ ob- 

 jective of the best class, one can 

 see almost as much as with any 

 higher powers, and can see all that 

 is needful to see in this department 

 of microscopical research, for he 

 might refer his specimens to expert 

 specialists in manipulation, in cases 

 when the use of such medium 

 powers proved insufficient for the 

 elucidation of the ultimate details. 



This paper was briefiy discussed 

 by Dr. Seiler and others and at 

 some length by Prof. Tuttle and 

 President Smith. The latter pointed 

 out the disadvantages in the plan 

 recommended by the author of the 

 paper and especially the difference 

 of image due to difference in the
