pasteurized, or cooked milk. Contrary to theory, cooked milk, 

 when fed to the calves used in these experiments, caused violent 

 scouring- in the majority of trials. A majority of physicians in 

 charge of children's hospitals corresponded with, favored the use 

 of raw milk for infants when the milk is known to be in perfect 

 condition, but favored pasteurized milk under ordinary condi- 

 tions. With one exception all the physicians corresponded with, 

 discouraged the use of cooked, or sterilized milk for infant 

 feeding." 



Rosenau* states that "Comparative observations upon in- 

 fants under the same conditions show that they flourish quite as 

 well upon heated milk as upon raw milk. Laboratory experi- 

 ments as well as chemical observations coincide with the view, 

 that heated milk is quite as digestible as raw milk. In fact it is 

 now claimed to be more so. Metabolism experiments indicate 

 that the utilization of calcium and iron in the body is more com- 

 plete in children fed upon boiled cow's milk, than in those fed 

 upon raw cow's milk." 



Stutzer 1 who conducted experiments of artificial digestion 

 reports in favor of boiled milk, while similar investigations made 

 by Ellenberger and Hofmeister 2 showed no difference in the 

 digestibility between raw and cooked milk. 



Rodet 3 who experimented with dogs noticed a slight dif- 

 ference in favor of boiled milk. Bruning 4 fed dogs, pigs, rabbits, 

 and guinea pigs with raw and sterilized milk and reports that 

 all results were in favor of the sterilized milk. Bruckler's 5 ex- 

 periments with dogs showed that the animals gained more in 

 weight on sterilized milk than on raw milk, but that their general 

 health, vigor and vitality was better when fed raw milk. Variot 

 observed no difference in the effect on infants between raw and 

 boiled milk. 



Peiper and Eichloff made post mortem examinations on num- 

 erous dogs which had been fed for prolonged periods on raw
