heated milk for raising calves in order to prevent their sufifering from 

 the bad effects of the presence of the germ. 



Effect on man. What effect the consumption of such milk in the raw 

 state may have on the human family, especially children, is not known. 

 The work of Larsen and Sedgwick of Minnesota, and of Oooledge of this 

 station indicates that children or adults may be affected, though not 

 necessarily detrimentally, by the consumption of raw milk containing 

 the abortus bacillus. The former report 425 complement fixation tests 

 of the blood of children, 17 per cent of which were positive. It is 

 claimed that the proportion of reactions would have been greater had 

 the tests been confined to children led with raw cow's milk.
