The significance of age, institutional life, and the condi- 
tions OF PREVIOUS LIFE AVITH REGARD TO THE AMOUNT OF INFECTION 
AviTH INTESTINAL PARASITES. — The soldiers admitted after seiwice in 
the Philippine Islands, among AApom was found a percentage of infec- 
tion more than twice as high as in any other class, were for the most 
part young men, their aA^erage age being 30.5 A^ears. They were also 
patients of recent admission, none haA^ing been in the hospital longer 
than three }"ears. We may discoA^er the relatiA^e significance of Phil- 
ippine seiwice as a condition favorable to infection with intestinal 
parasites by comparing the Philippine men with that class of patients 
Avho during the late war served in the reserve camps situated princi- 
pally in the Southern States. The average age of this latter class of 
men was 34.8 years, and all but four had been admitted to the hospital
