many. This ration is shown in Table No. 158. Likewise a request from the same source was received for a ration designed especially for American prisoners ill in enemy camps. This ration is shown in Table No. 159. Both these rations are now being supplied through Red Cross channels to American prisoners. A system of checking by receipts from individual soldiers furnishes satisfactory evidence that the rations are actually delivered.

With this war have come many new feeding problems. Much light is thrown on some of them by statistical surveys in the camps, but others call for special laboratory studies. Subjects which have been specially investigated by members of the Food Division are as follows:

(1) Dehydrated vegetables.

(2) Meat inspection and spoilage.

(3) The physicochemical properties of gluten.

(4) Relation of diet to specific muscular strength.

(5) Relation of diet to disease.

(6) New analyses of meat.
