EXPERIMENT STATION BULLETINS. 307 



teria; the intestines were hyperaemic filled with flatus and brown watery feces. There 

 was a laiL;(^ aniount of serous exudate and this was of a brownish color. The jjerms 

 were found in blood and or<?:ins. When a bouillon culture was injected underneath the 

 skin in the amount of one cubic centimeter, death was delayed, but the germs gave rise 

 to lesions wliicli wore fairly coiistant. A slight purulent condition was found beneath 

 the skin adjacent to the point of inoculation. IJsually the abdominal organs became 

 involved, following the same course as when the germ was introduced intra-peritoneally. 

 If one-tenth cubic centimeter was injected, the time of death was extended and the post- 

 mortem appearances were better marked if anything. 

 This germ was not inoculated into other animals. 



RESEMBLANCE TO THE COLON GROUP. 



This germ doubtless belongs to the serogenic group of bacteria. Tliis view is based 

 upon its morphology and cultural properties as well as its pathogenic tendencies. It 

 is. so far as we know, a non-motile bacillus, differing in this respect from the colon 

 group, but unfortunately, the motility of a germ is not the easiest to determine. At 

 times I have believed the germ to be motile, but it was never sufficiently marked and 

 constant to make a positive statement. I am in hopes that by passing it through a 

 series of animals I shall be able to establish the question of motility and flagella 

 production, but this must be a matter of the future. In its growth on gelatin and agar, 

 potato, milk, there is practical identity. In the production of gas, there is close 

 resemblance. Its relation to the thermal death-point, resistance, indol reaction, is 

 practically that of the colon and so far as pathogenesis is concerned, I have been able 

 to notice very little difference. For these reasons, while it is a distinct serogenic 

 micro-organism, I am led to believe that it is one of the colon group. It also corre- 

 sponds very closely to the Moore and Ward germ.
