ISTG there were exhibited three or four dynamos maiuifactiired by 

 Gramme, of Paris. One of these was purchased for the physical hibora- 

 tory of Purdue University and one by Professor Barker for the pliysi.-al 

 laboratory of the University of Pennsylvania. Professor Barker, doubt- 

 less, got his apparatus before Purdue, since it was nearby. As soon as the 

 exposition was over tlie machine belonging to Purdu(> was sent to Lafay- 

 ette and early in November, 1876, the first modern electric light ever seen 

 in Indiana blazed forth from the tower of the Purdue chemical laboratory. 

 It was one of the wonders of the age and was the talk of the newspapers 

 and the town for many weeks. It seems almost incredible to think that 

 twenty-seven years ago one electric light would cause such a commotion 

 in a community. But this fact should fully illustrate to the young people 

 how much more keenly we of advanced age can understand the progress of 

 science in our State. Prof. Joseph Tingley. at Asbury University, had a 

 room 20x:30 feet as a lectui'e I'oom and oiw Uxl2 feet for his store room. At 

 tlie present time tluM-e are four departmiMits of science teaching at De- 

 Pauw. namely, chemistry, physics, botany and zo.-Jlogy. Those depni-t- 

 nients are in cliai-ge of In-. W. M. Blanchard. clicmistry: Prof. .1. P. May- 

 lor, physics, and Prof. M<-]. T. Ciok, liiology. Eacli professor has an 

 assistant and tlieir ro<.ms. taken in tlie aggregate, amount to more 11., or 

 space than tlu> entiiv old college building of Asliury T'niversity. One of 

 the latest ac(juisitions at l>ePauw is the .Minshnll l.-ihoratory. siixb-tn feet, 

 three stories, constructed of stone, brick ami in.n, lirepro.f. and with the 

 most modei-ii ;ippliaii<-es for leaching chemistry ;ind physics. Plans are 

 now practically comi)l(>ted for the depart iiients of botany and zofilogy. 



One of the earliest contributicms to the ni,iteri;il in-osperity of Indiana 

 from the sciences was m;nle by geology. I h.-ive no time here to review 

 the voluminous geological reports which have been made from tinu' to 

 time in the history of our State. There are a few snlient points, however, 

 in the liistoi'v of economic geology which may prove of interest. 



I have already made allusions to the services of Dr. B. T. P.rown to 

 the geological develoi)ment of our State. 1 have now to speak of a period 

 in om- geological development of most i-emarkable significance. I refer to 

 the services of that distinguished scientist. Prof. K. T. Cox. Trained un- 

 der the Owens, he had imitated their zeal and their industry, and was 

 active in all his habits, both bodily and mental. lie i)uslied with utmost 

 vigor the investigations of a geological nature into the extent and charac- 

 ter of the coal deposits of the State. He early saw the importance of
