mals from scurvy for more than a few weeks when fed rolled oats 
and milk. 
Charts 4, 5, 6, and 7 show the effect of feeding dextrin, dextrose, 
sucrose, and starch with the standard ration of rolled oatsand 
whole milk. In every case some protection was afforded, al- 
though in the case of dextrose the protection was but slight. The 
appearance of these animals was better than that of animals re- 
ceiving only oats and milk, but their appearance was not nearly 
so good as that of the animals shown in Chart 2. The growth 
curves show considerable improvement over the growth curves 
of animals receiving no additional carbohydrate (compare Charts _ 
4, 5, 6, and 7 with Chart 8). This slight protection afforded by 
dextrin, dextrose, sucrose, and starch is explained by the findings 
of Hull and Rettger as cited above and also by the work of 
Hirschler (3). The latter showed that, zn vitro, sucrose, glycerol, 
dextrin, starch, and lactic acid completely prevented the forma- 
tion of indole, scatole, and phenol over a period of 10 days, from 
proteins which were inoculated with cultures of putrefactive or- 
ganisms. In the animal body the same carbohydrates did not 
completely prevent the formation of indole, scatole, and phenol 
in the feces of dogs fed a high protein diet, but they did ma- 
terially decrease the amounts of these products formed as com- 
pared with the amounts found in the feces of dogs fed a high 
meat diet but receiving no carbohydrates. | 
These results demonstrate beyond a doubt that a putrefactive 
flora in the intestine of the animal is instrumental in the produc- 
tion of scurvy, and that a diet which will cause a change in the 
flora from a putrefactive type to an acidophilus type will protect 
the animal from scurvy. ! 
Production of Scurvy by Grains Other than Oais. 
Lusk (4) makes the following statement, ‘It is important to 
remember that it has never been demonstrated that any kind of 
unmilled grain will produce scurvy.” If scurvy is the result of 
the retention of feces, and there can be little doubt. that such is 
the case, then any ration which will produce feces difficult to 
eliminate should produce scurvy. It has long been known that 
milk when taken in large quantities will cause severe constipa-
