1890.] MICKOSCOPICAL JOUENAL. 201 



The last paper of the afternoon was then read by Prof. Gage, on 

 '' The Transition from Columnar to Stratified Epithelium," and with 

 its discussion the session closed. 



TUESDAY EVENING. 



In the evening a conversazione was held in the hall on the second 

 floor of the Hotel Normandie, and a large number of visiting and local 

 scientists embraced the opportunity of getting acquainted with one 

 another. On a half dozen tables were microscopes displaying objects 

 of not only scientific importance, but also of popular interest. The 

 most discussed slides were two containing the blood of William Kemm- 

 ler, who was electrocuted at Auburn, N. Y. The blood taken from 

 the lower limbs was in its normal condition, but that from the brain 

 was abnormal, the corpuscles being irregular in size, the protoplasm 

 extending through the sides of some, and there were numerous gran- 

 ules mixed in with them. 



WEDNESDAY MORNING. 



Prof. M. D. Ewell read a report of the committee on medico-legal 

 microscopy. After some discussion, this report was referred to the 

 executive committee. Dr. Manton opened a discussion in regard to 

 the desirability of omitting the working session from this meeting, be- 

 cause of the great number of papers to be read. After a lengthy dis- 

 cussion, in which Professors Burrill, Claypole, Ewell, Gen. Cox, Dr. 

 Fell, and Mr. Tolman participated, it was decided to hold the session 

 in the afternoon, beginning at 2 o'clock. At 3.30 all who desire may 

 adjourn to another room and listen to the reading of papers. 



The first paper of the day was on " Some Experiments to Determine 

 the Limit of Vision as Related to the Size of the Object Observed," by 

 Prof. M. D. Ewell. A small square of white paper pasted on a black 

 background was not seen as far as a black square on a white background, 

 contrary to what the professor had supposed. 



Ex-Gov. Jacob D. Cox, of Cincinnati, spoke on " Representation of 

 the Society at the World's Fair, Chicago, 1893." The judge said that 

 if the exposition takes the proportions expected there will be an oppor- 

 tunity of getting together the leading scientists of the world, hence this 

 Society should be represented, but how to go about it was the question. 

 Mr. Tolman, of Chicago, delegate from the Illinoig Microscopical Asso- 

 ciation, said they had already been discussing the matter, and were 

 willing to follow any course mapped out. Dr. Mcintosh, of Chicago, 

 favored a scientific hall in which scientific lectures could be held and 

 work done, instead of having the ordinary exhibition. 



On motion of Prof. Seaman, of Washington, President Fell appointed 

 the following committee to consider the matter: Ex-Gov. Cox, Dr. 

 Mcintosh, Prof. Ewell, Mr. Tolman, and Dr. Miller. The committee 

 was given the power to increase its membership. 



The next paper was read by Dr. A. Clifford Mercer, of Syracuse, N. 

 Y., ''On a Mooted Matter in the Ordinary use of an Eye-piece in 

 Photo-Micrography." This paper was discussed by Gen. Cox, Prof. 

 Burrill, Prof Claypole, Messrs. Barr, Tolman, and Dr. Mcintosh. 



The paper by Prof. Kellicott on "Recent Methods of Investigating 

 Microscopic Animals," was withdrawn.
