This work furnished the material of the 

 wonderful campaign by which Gorgas cleansed 

 the Panama Canal zone of yellow fever, and 

 so made possible the completion of that work. 

 Gorgas came to Panama from Havana, which 

 he had also cleansed of yellow fever in about 

 a year, though the place was a famous hot- 

 bed of the disease. His method was to attack 

 the mosquito in its breeding places and to ex- 

 clude it as far as possible from contact with 

 fever cases. 



Dr. IToguchi's work on filter-passing germs is 

 well known. It is also well known that from 

 time to time the suggestion has been offered 

 that the spirochetes pass through two stages 

 of development, one of these stages being of 

 an extremely minute type. Whether or not 

 this view will receive confirmation through the 

 new discovery remains to be seen. In all 

 matters bacteriological it is necessary to keep 

 an open mind imtil proof of an absolute kind 

 has been forthcoming.
