of the Light Battery and Cavalry Troop, which was largelj' at- 

 tended, and very much enjoyed by the visitors. Mr E. H. Grif- 

 fith was elected to take charge of the working session next year, 

 and Prof Gage of Cornell was also selected by the nominating 

 committee by special vote to make the necessary arrangements 

 and have charge of the working session at the Columbian Expo- 

 sition. 



Twenty -eight papers were offered to the society, several of 

 which had to be read by title, owing to want of time to read 

 them in full. Committees were appointed to consider and re- 

 port on the steps necessary to be taken to secure uniformity in 

 the screw threads of our objectives, without reference to the 

 taps now in use, made by the Royal Society, as its co-operation 

 could not be secured ; also to consider and report upon the pos- 

 sibility of publishing or otherwise securing for general circula- 

 tion a journal which shall present a review of current micro- 

 scopical literature, so that the humblest worker in the most 

 remote corner of the United States may, by the aid of such a 

 journal, have at his hands the substance of the world's work in 

 microscopy. The city of Washington offers particular advan- 

 tages for such an enterprise, because here are taken all the sci- 

 entific periodicals of the world, the contents of which are freely 

 accessible to any one who chooses to make use of them. 



Dr. M. D. Ewell, of Chicago, was elected President for the 

 next year. 



Fifty-three new members were elected, a number above the 

 average, representing every part of our great country. 



On Saturday morning the members remaining in tlie city went 

 to Mt. Yernon on an excursion tendered them by the Micro- 

 scopical Society of Washington. The day was a delightful 

 one, and the pilgrimage to this celebrated place closed a meet- 

 ing that, while not large in numbers, may be regarded as an 

 agreeable and a successful one.
