The working session, which proved to be a valuable feature of the 

 Buffalo meeting, was under the direction of Stephen Y. Howell, M. 

 D., who, by his close attention and ardent labors, insured the most suc- 

 cessful one yet held by the Society. 



THURSDAY EVENING. THE SOIREE. 



The notable feature of the meeting of the microscopists was the mi- 

 croscopic exhibit given for the benefit of the general public. In pre- 

 vious years these exhibitions have usually been held in large halls, de- 

 sirable because of their facilities for the easy handling of crowds, but 

 this time it was deemed proper to hold it in the Library building, where 

 the various handsome rooms and scientific and art collections would 

 substantially add to its attractiveness. The Library Association gener- 

 ously gave the use of the entire structure, the other organizations inter- 

 ested consenting. So that as well as seeing the microscopic display the 

 visitors might examine the treasures of the Art Gallery, the Society of 

 Natural Sciences, and the Historical Society. Furthermore, citizens 

 owning microscopes were asked to contribute them for the occasion, 

 and the response was such that when evening came nearly 250 instru- 

 ments were ready for use. 



At 8 o'clock the microscopical soiree was in successful progress. 

 The illuminated building presented a fine appearance from without. 

 Inside it was filled with light and life. The tables supporting micro- 

 scopes were in the main room in the basement, in the Library rooms, 

 and the rooms of the Historical Society. In the Art Gallery, Dr. Lee 

 H. Smith entertained the visitors with his talking and whistling phono- 

 graph. On the library floor music was furnished throughout the 

 evening. 



Most of the objects chosen for exhibition were those which would 

 best serve to engage and please the average visitor's attention rather 

 than those of the most particular scientific interest. Among them were 

 exquisite crystals of precious stones and metals, alloys, disease growths, 

 animal tissues,. forms of vegetable and shell life, hair, the parasites of 

 various creatures, anatomical and physiological specimens, bacteria, 

 trichinae, micro-photographs, etc. 



Dr. George E. Fell, chairman of the Exhibition Committee, and other 

 members of that committee, have every reason to congratulate thenar
