PROCEEDINGS OF SOCIETIES. 



ELEVENTH ANNUAL MEETING, AMERICAN SOCIETY OF 

 MICKOSCOPISTS. 



TT is a cause of regret, in a country where thousands of individuals 

 -*• have not only shown themselves interested, but, in very many 

 instances, have added to our knowledge in microscopical science, that 

 so many should refrain from participating in the annual doings of 

 the National Society of Microscopists. We have repeatedly urged 

 the point, that the presence of those interested in microscopy and 

 general science at these meetings is not so much a direct stimulus to 

 the Society itself, as it is a refreshing mental invigoration to the indi- 

 vidual, and that the absence of the individual is to be looked uj)on 

 more as a personal loss, a lapsing into a state of innocuous desue- 

 tude, which is innocent only as touching the Association, for its 

 baneful influence upon the person cannot be estimated. Those who 

 are accustomed to attend the annual meetings of this Society are 

 noticeable as the men who grow, and this growth is markedly 

 observable in the transactions which are given out under the sanc- 

 tion and authority of this scientific body. The comparatively small 

 attendance at the eleventh meeting of the American Society of Micro- 

 scopists is traceable to several causes : First, the illness of the Secre- 

 tary, and the consequent unavoidable delay in the publication of the 

 transactions of the Society for 1887, acted as a damper on the enthu- 

 siasm of not a few. Second, the postponement of the time of meet- 

 ing from the middle to the latter portion of the month interfered with 

 the previously arranged plans of many who would otherwise have 

 been present; and, lastly, the inaccessibleness of Columbus by boat 

 and rail. 



In spite of these drawbacks, however, a fairly representative 

 audience was present when President Kellicott called the meeting to 

 order on the morning of August 21. 



Owing to the sudden illness of Secretary Burrill, the Treasurer, 

 Dr. Mosgrove, was elected temporarily to fill the position. The
