MICROSCOPY IN INDIANA. 



BY A. W. BKAYTON, M. D. , INDIANAPOLIS, INDIANA. 



The American Microscopical Society was organized and 

 held its first meeting here in 1879. The old Indianapolis 

 Microscopical Society held its last meeting, I think, the same 

 year. The use of the microscope has increased yearly in our 

 city and State since that time, but there is no society ; the 

 reason, I think, is that all interested in work now do it alone 

 at home. I have sold, mainly as agent for Bausch & Lomb, 

 or for Mr. Griffith when his stand was made by them, nearly 

 $3,000 worth of stands and accessory apparatus to physicians 

 in this city and vicinity. We have several biological labora- 

 tories in the State. Notable work has been done by Professor 

 John M. Coulter, mainly in the years from 1880 to 1892, at 

 Wabash College, in botanical histolog}' and physiology. Also, 

 since 18S5, in Purdue University, by President Coulter's bro- 

 ther, Professor Stanley M. Coulter, in general biology ; to say 

 nothing of the work of Professor C. R. Barnes and Professor 

 Arthur. The substantial contributions of these scientists to 

 botany are well known the world over. 



A very considerable impulse was given to embryological 

 research in the State University at Bloom ington by Professor 

 Kingsley, formerly associate editor of the American Naturalist. 

 Unfortunately for biological research in this State, Professor 

 Kingsley only remained two years at the university. One of 

 his most assiduous students was Dr. Robert Hessler, now 

 demonstrator of pathology at the Indiana Medical College. 

 His series of slides, over 3,000 in number, covers nearly the 

 whole range of human pathology, and is one of the most 

 valuable in the West. His knowledge of analine stains is 

 perfect, and his preparations are very fine. Associated, also, 

 with the work in that college is Professor Theodore Potter, 

 professor of bacteriology. He has given a great impulse to
