"This kingdom (bacterial) is a veritable fairyland. Its 

 inhabitants are more numerous than the sands of the sea, 

 and as varying in their functions as are the inhabitants of 

 the animal and vegetable kingdom." "Only a, "few of 

 them work serious harm to man, and even the harm which 

 these do is not out of harmony with nature as a^whole. 

 The world as we see it can be maintained only by^a har- 

 monious succession of life and death." (Flick, Consump- 

 tion, a Curable and Preventible Disease.) 



"When we reahze that the majority of all deaths is still 

 from preventible causes, most of which are already quite 

 familiar to us, it is manifest that this must be in a large 

 measure due to an indifference on our part to put into 

 practice even the knowledge which we already possess for 

 their prevention." (Abbott, Hygiene of Transmissible 

 Diseases.) 



"The belief is growing stronger that the communicable 

 diseases are more often spread through the intermediation 

 of mild, latent and unrecognized cases than through the 

 agency of fomites, that is, inanimate objects." (Rosenau, 

 Disinfection and Disinfectants.)
