TABLE 7.—WEIGHT OF RATS 11 TO 16 COMPARED WITH
AVERAGE WEIGHT OF RAT OF SAME AGE

Rat	Age, Days	Final Weight, gm.	Average Weight of Rat of Same Age, gm.
11	106	112	167
12	106	144	167
13	99	90	162
14	106	95	167
15	92	105	153
16	96	74	158

That these losses in weight were not due to any inherent weakness in the rats is shown by the fact that by feeding Rats 11 to 16 for one week after the termination of the experiment with Osborne and Mendel’s “mixed food” (a mixture of dog bread, sunflower seeds, vegetables and meat) very large gains were secured in every instance, ranging from 14 to 35 gm.

The growth curves for Rats 7 to 16 are shown in Charts 3, 4 and 5.

To conclude, a comparative feeding of four male white rats during eleven weeks, showed, if anything, a slightly greater, but insignificant, increase in weight for Sanatogen over commercial casein. In a ration in which artificial had been substituted for natural protein-free milk, Sanatogen showed no advantage over commercial casein in checking the failure in weight of the rats.—(From The Journal A. M. A., Nov. 21, 1914.)
