The Indiana Academy of Science is engaged in the publication of 
its proceedings since its establishment several years ago. The publi- 
cation is in the hands of a committee consisting of Prof. O. P. Hay, 
of Butler University; Prof. C. A. Waldo, of Depauw University, 
and Pres. John M. Coulter, of the Indiana University. No State 
organization holding its meetings but once a year has better meetings 
with a greater variety of interesting papers than this association. 
The American Microscopical Society has issued a special circular 
which may be obtained by all interested, of Dr. William H. Seaman, 
Secretary, Washington, D. C. The circular gives an outline of the 
proceedings of the last meeting of the Society, held at Rochester Aug. 
9-12, 1892, from which we gather the following items: Twenty-nine 
new members were elected and twenty-seven papers were presented. 
The following officers were elected for the ensuing year: President, 
Prof. J. D. Cox, of Cincinnati; Vice-Presidents, Dr. Geo. M. Stern- 
berg, of Brooklyn; Dr. A. C. Mercer, of Syracuse; Secretary, Dr. 
Wm. H. Seaman, of Washington; Treasurer, Mr. Charles C. Mellor, 
of Pittsburg. The circular also gives the following announcement 
regarding prizes offered by the Society: | 
The following sums of money have been placed at the disposal of 
the society, to be given as prizes for the encouragement of microscopi- 
cal research, and Profs. Gage, Kellicott, and Seaman were appointed a 
committee to prepare the conditions on which they should be granted. 
The competition will be open to members of the society and to those 
who make application for membership before submitting their papers 
to the committee: 
Two prizes of $50, two prizes of $30, two prizes of $25, two prizes 
of $15. The committee have prescribed the following conditions: 
One prize of $50 for the best paper which shall give the results of 
an original investigation relating to animal life, made with the micro- 
scope, and not less than 3000 words in length. The methods by which 
the results are obtained to be given in full.
