DUST AND ITS DANGERS. 57 



Many of the conclusions to which we shall 

 be forced, and many of the practical hints as 

 to personal action which we shall gain, apply 

 equally to some of the other bacterial diseases. 

 But these other diseases are apt to make peo- 

 ple early and more or less seriously ill, and so 

 they come under the charge of the physician, 

 who should on the spot suggest measures to 

 prevent their spread. On the other hand, per- 

 sons affected with consumption very frequently 

 go about for weeks and months among their 

 fellows, always liable, through ignorance or 

 carelessness, to transmit the disease-producing 

 germs to others, as well as constantly repoi- 

 son themselves, and thus greatly diminish the 

 chances of recovery which they might other- 

 wise anticipate. 



It is most important then that everybody 

 should have some definite knowledge about 

 the cause and mode of spread of consumption, 

 since it spares no age and no class and is the 

 most widespread and fatal of all the diseases 

 known to man, and is in large degree, could 

 we but secure thorough cleanliness in the air 

 we breathe and the food we eat, a distinctly 

 preventible disease.
