204 PROCEEDINGS OF THE INDIANA ACADEMY OF SCIENCE. 



CoUett called attention to the interesting animal life found in some of the 

 eaves in southern Indiana. In Donnelson's cave "thousands of bats gather 

 in the fall and remain through the winter in hibernation, hanging in clusters, 

 like swarms of bees, from the ceiling or sides of the cave; the clusters of bats 

 varying from 20 to several hundred, or in measure, from a quart to a bushel." 



He also records other species of animals found in Connelley's, Hamer's 

 and Donnelson's eaves. Eyeless fishes, crustaceans and crickets are men- 

 tioned. Collections were made by Doctors Elrod and Sloan and forwarded to 

 Prof. A. S. Packard and Dr. E. D. Cope, who identified the specimens. 



This appears to have been the first study made of the fauna of Indiana 

 eaves, so exhaustively continued recently by our own Dr. Eigenmann. 



Under instructions from Professor E. T. Cox, State Geologist, Dr. George 

 M. Levette assisted by ISIr. Caleb Cooke, in 1875, took soundings and 

 temperatures of 13 of the small lakes in northern Indiana. 



Besides making soundings and taking temperatures of the water, these 

 gentlemen made notes on the fishes and moUusks of the lakes examined. 

 This was, so far as I know, the first serious attempt to learn anything about 

 the fauna of our northern lakes. Dr. Levette's report was published in the 

 Seventh Annual Report of the Geological Survey of Indiana, for 1875. It is 

 an extremely interesting and valuable document. Considerable attention 

 was given to the fishes and turtles and a great deal to the mollusks. 



Dr. Levette was i)rimarily a conchologist. In this report he records 

 some 20 species of Unionidn> which he obtained in Indiana north of the 

 Wabash. He also lists 19 species of univalves which he collected in the 

 same waters and which had been identified for him by John W. Byrkit of 

 Indianapolis. He also recorded 9 species of turtles from the same region. 



Dr. Levette was the first naturalist I ever met. As a young man I spent 

 a portion of the summer of 1876 in Indianapolis in the office of Professor 

 Daniel Hough in the bookstore of Bowen and Stewart, on Washington Street. 

 Professor Hough and Dr. Levette were intimate friends and were frequently 

 1f)getlier. Professor Hough, one of the best men I ever knew, was interested 

 in archeology, as also was Dr. Levette. They l)oth occupied rooms in a 

 iiiiilding which 1 think, stood at the southwest corncT of W^ashington and 

 Illinois streets. I frequently visited them there. In the rooms of each were 

 ■what seemed to me at that time great quantities of specimens of Indian 

 axes, mortars, spear and arrow heads, Unios and other mollusks, and turtle 

 shells. 



Many of the shells and turtles were the collections Dr. Levette had made 

 the previous summer in northern Indiana. And I remember with what de- 

 light he exhibited them to me, and how interested he was when I showed 

 some slight knowledge of the habits and distribution of some of the species, 

 gained from my days of loitering as a boy along Wild Cat Creek and "on the 

 banks of Deer Creek."
