144 INFECTION AND IMMUNITY 



Philippine Islands, owing to the difficulties encount- 

 ered in the execution of well-known preventive meas- 

 ures, there has been considerable mortality from filth 

 diseases. But when we consider that our troops 

 have been engaged in active operations in a tropical 

 country, where all forms of intestinal flux are preval- 

 ent, and where they have been more or less exposed 

 to infection by the germs of cholera and bubonic 

 plague as well as by that of typhoid fever, it is safe to 

 say that the sanitary record of our army in the Philip- 

 pines is unsurpassed by that of any other body of 

 troops which has been exposed in a tropical country 

 under similar conditions.
