182 PROCEEDINGS OF THE INDIANA ACADEMY OF SCIENCE. 



the college was moved to Ir\niigtoii and chemistry was taught by Professor 

 Hay for several years. 



In 1874 I became Professor of Chemistry at Purdue. I immediately 

 fitted up a laboratory where large numbers of students could be accomodated. 

 As I remember, we had working desks for about 2.5 or 30. During 1874—75 

 the students in chemistry at Purdue University, among other things, were 

 taught the making of ordinary chemical compounds as instruction in applied 

 chemistry. A large and ^^ery fine collection of these compounds was pre- 

 pared and exhibited at the World's Fair in Philadelphia in 1876. As far as 

 I know, this was the first chemical exhibit of a college or university at a 

 World's Fair. There may have been earlier exhibits but I have not happened 

 to come in contact with them. At the time I left Purdue in 1883 the working 

 laboratory had become enlarged and more fully equipped and with a larger 

 number of working students. 



Among the men who succeeded me at Purdue have been many whoso 

 eminence has been acknoA\iedged. Among them were Robert B. Warder, 

 who was one of the first original workers in i)hysical chemistry in this coun- 

 try. He originated the methods of studying chemical reactions by means 

 of their speed and the factors which retarded or accelerated the reaction. 



Following him came Professor Xeff who as a worker in organic chemistry 

 obtained world wide renown. After a distinguished career at Purdue, he 

 was made head Professor of Chemistry in Chicago University, where he still 

 furllier distinguished himself until his premature death, the result of over- 

 work. H(' came to the notice of Purdue University in the following manner. 

 The late Professor Joj' of Columbia University wrote to me that he knew a 

 young man whom he had met during his residence in Germany who had dis- 

 tinguished himself most signally in his chemical studies and who was a Har- 

 vard graduate and desired to get a professorship in the United States. I 

 called attention of the Purdue authorities to Professor Joy's commendation 

 and in this way Professor Xeff came to Purdue. F'ollowing Professor Neff, 

 Dr. Stone became Professor of Chemistry. Had he not so signally distin- 

 guished himself as an E.xecutive Officer he would ]>e Avorthy of a place among 

 the stelligeri by reason of his researches in agricultural chemistry. 



Among the younger men who have taught chemistry in Indiana and who 

 have made a reputation for themselves I desire to call attention to W. G. 

 Emery. He was Professor or Assistant Professor of Chemistry at Wabash 

 for some time. He was appointed to the chemical service of the Bureau of 

 Chemistry after a brilliant examination by the Civil Service Commission, 

 and has distinguished himself particularly in pharmaceutical chemistry in 

 the position which he now occupies. 



Among the earlier workers in chemistry in Indiana not connected with 

 didactic institutions I must recall the services of Dr. Levette in the Geolog- 

 ical Survey. When I first came to Indianapolis in ISfJS, I made the acquaint- 

 ance of Dr. E. T. Cox, the State Geologist and through him of Dr. Levette.
