lasting for about a week in each case. By agglutination tests, 

 the authors arrived at the conclusion that the epidemic was 

 due to bacilli of the Flexner type. 



During the fiscal year 1912-1913, excluding cases of amoebic 

 and other extraneous types, there were treated in our service in 

 the Philippine General Hospital 266 cases of acute colitis. 



Distributed according to ages, these cases were as follows :

There were 191 males and 75 females. 



The total mortality in the 266 cases was 49, or 18.4 per cent. 

 Autopsy was performed on 29 of the cases. The mortality 

 among males was 34, or 17.8 per cent, and among females 15, 

 or 20 per cent.

In considering the mortality statistics in these cases, it must 

 be remembered that they were all hospital cases and consequently 

 represented patients with severe clinical symptoms. 



The mortality from this disease in other hospitals is given by 

 various authors as follows: 



Japan, 16.5 to 30.2 per cent. Ceylon during 1903, 28.7 per 

 cent. British New Guinea in 1902-3 at 22.8 and 26.6 per cent, 

 respectively. In Singapore where the dysentery is considered 

 mild, the mortality in the hospitals in 1902 was not less than 

 25.4 per cent, and in the neighboring state of Selangor it reached 

 34 per cent. In Trinidad it stood at 30.7 per cent, in German
