THE AMEKICAN MONTHLY 



[September, 



Ernst Gundlach at this point read 

 a short note explaining a former pa- 

 per on the question of making homo- 

 geneous immersion objectives with 

 adjustable mounts. Edward Bausch 

 read a paper on the universal or so- 

 ciety screw for the microscope. On 

 motion of Pi'ofessor Burrill, Mr. 

 Bausch and Professor W. A. Rogers 

 were appointed a committee to con- 

 fer with the Royal Microscopical So- 

 ciety to secure, if possible, some un- 

 derstanding in the matter of the soci- 

 ety screw. The next paper read was 

 by Professor Henry Mills, of Buffalo, 

 entitled ' Thoughts on the Spongi- 

 adae.' Dr. George E. Blackham read 

 a paper written by W. H. Bulloch on 

 the ' Magnifying Power of Micro- 

 scope Objectives.' 



Dr. R. H. Ward, of Auburn, read 

 by abstract his paper on ' A New 

 Lens Holder and Iris Illuminator.' 



President Cox called for the report 

 of the nominating committee. Pro- 

 fessor Henry Mills, of Buffalo, chair- 

 man, read the report as follows : — 



President — Professor W. A. Rog- 

 ers, Cambridge, Mass. 



Vice-Presidents — H. F. Atwood, 

 Rochester ; Professor Chas. H. Stow- 

 ell, Ann Arbor, Mich. 



Secretary — Professor D. S. Kelli- 

 cott, Buffalo. 



Treasurer — Dr. Geoi'ge E. Fell, 

 Buffalo. 



Executive Committee — Charles E. 

 Shepard, M. D., Grand Rapids, 

 Mich.; A. B. Harvey, D. D., Taun- 

 ton, Mass.; L. M. Eastman, M. D., 

 Baltimore, Md. 



The report was adopted. 



The report of the committee on 

 eye-pieces was called for and read by 

 Dr. R. H. Ward. The report re- 

 commended that standard sizes of 

 eye-pieces be adopted, and suggested 

 a method of establishing a uniform 

 system of nomenclature. 



Professor Rogers gave a descrip- 

 tion of his method of making fine 

 rulings on glass. An interesting dis- 

 cussion followed. The treasurer's 

 report for the past year showed a bal- 



ance on hand of $380.53, which will 

 be augmented by $440 when the un- 

 paid dues are settled. 



At the afternoon session J. F. 

 Brownell read a paper on ' An Orig- 

 inal Method of Staining and Mount- 

 ing Pollen.' Dr. Blackham read a 

 paper written by Dr. A. C. Mercer 

 on ' An Improved Form of Watch 

 Glass.' A specimen was exhibited. 

 President Cox said he had used ordi- 

 nary salt-cellars for the same pur- 

 pose. 'A New Mounting Medium' 

 was the subject of Professor H. L. 

 Smith. The medium was a com- 

 position of arsenic and antimony. 

 Professor Smith explained the mode 

 of preparation and referred to its pe- 

 culiar advantages. 



The subject of Mr. F. M. Hamlin 

 was 'An Ideal Slide.' He made a 

 a diagram of a slide in which the cell 

 was sunk below the surface. The 

 cover was attached at points where 

 the cement could not affect the mount- 

 ing medium. He said such a slide 

 would cost more than those in com- 

 mon use, still its advantages would 

 make it desirable even at an increased 

 cost. Professor Smith exhibited a 

 grooved slide which he had found 

 useful. President Cox said the sand 

 blast might be utilized in the manu- 

 facture of such slides as Mr. Hamlin 

 described. The paper on a ' Cover- 

 glass Cleaner ' was read by Secretary 

 Kellicott, in the absence of the au- 

 thor, F. L. James. Secretary Kelli- 

 cott read the following letter from the 

 newly-elected President, W. A. Rog- 

 ers : ' I have been deeply moved by 

 the expression of confidence shown 

 in my election as president of the So- 

 ciety for the ensuing year, but I am 

 certain the best interests of the Society 

 would not be sei"ved by my accept- 

 ance. It is my present purpose to be 

 absent from the country during the 

 summer and fall of 1885. Will you, 

 therefore, communicate to the Society 

 iny declination of the great honor 

 conferred. I need not say that it will 

 always be both a duty and a pleasure 

 for me to do anything in my power to
