The Rochester Microscopical Society, after an existence of two 
years, during which time it became the largest organization of 
the kind in this country, has drawn around it sections in other 
departments of science, and has thus given origin to a new soci-

it will hereafter be a section. The recent annual reception of the 
new academy was one of the largest and best of such entertain-
