All over the mucous membrane of the colon from coecum to rectum 

 were found extended and numerous ulcers. The ulcers were in the 

 main situated across the intestine, of a rather longish shape. They 

 were ordinarily sharply contoured and had a clean bottom. All ulcers 

 stretched down into the submucous membrane. Only the ulcerations in 

 the rectum had the character of erosions. The healthy parts of mucous 

 membrane between the ulcers were swollen, pale and oedematous. No 

 considerable swelling of the glands. 



From the stool and from the ulcers growth of numerous colonies of 

 the typical Morgan bacilli. 



VII. Man, twenty-one years old. Suddenly taken ill with severe 

 abdominal pains, tenesmi and stools, containing blood and mucus 

 ten to fifteen times a day. Often hemorrhages pr. rectum. Excessive 

 prostration. Stools at last chocolate coloured, stinking, containing big 

 necrotic fibres of tissue. Temperature about 38°C. 



Death in emaciated condition on the eleventh day of disease. 



Post-mortem examination: On opening the abdominal cavity the lower 

 parts of the omentum were found discolored, slightly covered with pus 

 and attached to the paries of the pelvis. In the small pelvic cavum 

 were found 50 cc. of pus. 



The outside of the small intestine was a little hyperemic in the 

 lower parts, while the serosa of the colon was considerably injected, 

 and fragile. In the mesenterium several swollen, excessive injected 

 glands. 



After opening the colon there were found considerable alterations of 

 this intestine. Nearly all the mucous membrane had been dejected 

 and in its place was found an immense ulcer interrupted here and 

 there by small isles of membrane, that was blood coloured and exces- 

 sively oedematous. The ulcers in many places bared the muscle of the 

 intestine and even perforated it so that only the serosa remained. 

 Very often the process was necrotic, but there were no veritable per- 

 forations of the intestine. 



Often there were thick brown necrotic fibres (dejected mucous mem- 

 brane) attached to the ulcerating intestine; or the bottom of the 

 ulcers was filled with a purulent gangrenous and smeary covering. 



From the feces and the ulcers were isolated numerous colonies of the 

 typical Morgan bacilli and a strain of proteus. 



VIII. Man, forty years old. Suddenly taken ill with numerous stools 

 consisting of mucus, blood and pus. Temperature between 38 and 

 39°. After the first week of disease the stools became purulent, as if a 

 large ulcer was continually discharging pus.
