SIX TEXT FIGURES 
In my preliminary paper, published in 1918,(5) I reported 
upon the employment of serum by various methods in a limited 
number of cases of bacillary dysentery. Fortunately, I have been 
able to continue my observations on a larger number of cases. 
During the twelve months of 1918, there were admitted to the 
medical wards one hundred sixty-four cases of bacillary dysen- 
tery. With the exception of two cases all were Filipino patients. 
One of the two was a Japanese, and the other was an American 
who had been in the Philippine Islands a long time. Both sexes 
were represented in these studies; the sex incidence was as 
follows :

AGE INCIDENCE 
It is common experience that no age is exempt from the dis- 
ease. It appears from my series that young adults are most 
subject to attack. The age incidence is shown in Table 2.
