Variola : Pox. 377 



should be tested by long or vigorous driving before they are killed 

 for food, and all milk devoted to the production of butter and 

 cheese should be Pasteurized or sterilized before use. It might 

 well be questioned whether the clearing and exposure of infecting 

 places should not be undertaken by the state as a sanitary measure. 

 In view of the fact that a milch cow may not show symptoms 

 of the disease, and yet yield deadly milk, and considering that 

 the owner cannot always tell whether she has been in the infect- 

 ing woods, or having been in, whether she is infected, it becomes 

 an important public health question whether such a source of 

 deadly disease should be perpetuated, where human food is open 

 to contamination.
