532 BACTERIA IN CERTAIN INFECTIOUS DISEASES. 



ply one portion remains perfectly healthy, while another, and usually the 

 most filthy portion, may be decimated by the scourge. 



The experimental evidence recorded, and the facts just stated, seem to 

 justify the recommendation that the dejecta of yellow-fever patients should 

 be regarded as infectious material, and that such material should never be 

 thrown into privy vaults or upon the soil until it has been completely disin- 

 fected. 



This rule thoroughly enforced, together with an efficient quarantine ser- 

 vice and proper attention to the sanitary police of our exposed seaport cities, 

 would, I believe, effectually prevent this pestilential disease from again ob- 

 taining a foothold within the limits of the United States.
