DESCRIPTION OF EXPERIMENTS. 
1. Experiments with the Fungi of Contagious Disease. 
The season’s operations with contagious-disease experiments were 
developed principally_ from two points of departure: the first a 
single insect larva, indeterminable as to species, fouud April 17 
dead and covered with the fungus of white muscardine, in a plowed 
corn field near Urbana; and the second a small lot of chinch-bugs 
dead with the same fungus infection, received from Chancellor 
Snow, of the University of Kansas, about May 15. From the first- 
mentioned material numerous cultures were made, and infection 
experiments were conducted on chinch-bugs, cabbage worms, and 
other insect larvae, the series of operations dependent upon this 
original specimen extending from April 21 to September 20. From 
the second lot various laboratory and field experiments were started 
—twenty-one in number—extending from May 25 to October 10, 
all having the character of direct or indirect exposures of living 
cliinch-bugs to contagion or infection by means of these dead 
specimens obtained from Dr. Snow.
