Six rats per set. Weight on the first day:

A 76 B 80

For five days both A and B were fed on the "synthetic diet." On the 5 day:

A 90 B 94

From now on A was fed on the "synthetic" and B on the "synthetic" without the salt mixture. Both sets continued to gain until the seventh day, when the weights were:

A 97 B 100

From then on B began to lose, though A continued to gain until the 33 day, when the weights were:

A 130 B 89

A now began to lose rapidly, far more so in fact than B. On the 51 day the weights were:

A 117 B 84

And on the 80 day:

A 93 B 81

During the next five days one rat each from the experimental and the control died. On the 86 day:

A 98 B 84

From now on both were given the regular diet. On the 96 day:

A 147 B 124

The experiment shows clearly the importance of inorganic salts (or mineral matter).

Comparison of Regular Diet and Regular Diet Minus Water. Five rats per set. Weight on first day:

A 142 B 143

For six days both A and B were fed on the regular diet. On the 6 day:

A 148 B 150

Both A and B continued to get the regular diet, but B no longer received any water. On the 21 day:

A 185 B 158

At this point it was decided to withdraw meat and milk from the diets of A and B, on account of their large water content; A of course still continued to get their regular water supply. On the 36 day:

A 198 B 156

It was evident that there was still a considerable quantity of water in the food offered; hence it was decided from now on to feed nothing but dry grains, - oats, corn and rye. A therefore got the dry grains plus water, and B the dry grains without any additional water. On the 55 day

A 204 B 120

Water was now added to the diet of B. On the 63 day:

A 196 B 154
