It may be stated here that the etiologic agent was not isolated 

 in all of the cases of either entamoebic or bacillary colitis here 

 recorded. In the majority of the cases either the entamoeba 

 or the dysentery bacillus was isolated, but in the remainder 

 the diagnosis has been based on the gross and microscopic 

 examinations. 



No serious attempt has been made here to differentiate the 

 cases of bacillary colitis into types corresponding to types of bac- 

 teria, the bacteriological diganosis, when made, having been based 

 chiefly on agglutination with a polyvalent antidysenteric serum. 



DUODENAL ULCERS 



A review of the intestinal lesions encountered would not be 

 complete without reference to the duodenal ulcers. 



Nine cases of duodenal ulcer have been encountered in the 

 series, 6 of which had perforated. In no case had the clinical 

 diagnosis of duodenal ulcer been made. In 2 cases a diagnosis 

 of cholecystitis was made, and in 1 cholecystectomy was per- 

 formed. Severe anaemia was apparently prominent in 2 cases, 

 for in 1 case the diagnosis of pernicious anaemia and in another 

 that of secondary anaemia had been made. 



Eight of the ulcers were in the first part of the duodenum, 

 while one involved the orifice of the common bile duct, so that 

 the bile duct emptied into the base of the ulcer. Contrary to 

 rule, 7 of them occurred on the posterior wall, while 1 was 

 on the anterior wall, and the position of the other was not 

 recorded. Three occurred in the third decade of life, 3 in the 

 fourth, 2 in the fifth, and 1 in the sixth. There are in the de- 

 partment the records and specimens of 2 cases, not included in 

 this series, of duodenal ulcers in infants, 1 aged 6 months and 

 1 aged 7 months. 



In the same series, 15 peptic ulcers of the stomach have 

 occurred. 



NONSPECIFIC OR UNCLASSIFIED INFLAMMATORY LESIONS 

 OF THE INTESTINE 



This very important group includes 57 cases, 35 of which 

 occurred in infants and 22 in adults. 



Reference to Table VI will show that there was sufficient 

 explanation for the intestinal lesions in all but 5 cases in 

 adults. These 5 cases were examined for cholera vibrios un- 

 successfully, and their etiology has not been explained. The 

 majority of the cases in infants were also found negative bac- 

 teriologically for cholera, and none of those included in this 

 table presented the characteristic anatomical lesions of cholera. 

 Nor were any of these cases in infants of the type of a bacillary
