"The most important articles of diet for a polar expedition we found to be pemmican, cranberry sauce, tea, coffee, chocolate, preserved milk, sugar, ham, cheese, bacon, oleomargarine, lard, pickles, lime juice, dried fish, beef-soup tablets, wheat, corn, rye flour, rice, hominy, oatmeal, dried vegetables, and a liberal supply of all kinds of canned vegetables, particularly canned tomatoes, peas, beans, corn, canned soups, and dried fruits. Lime juice was not served regularly to the members of the expedition, and I think nothing is to be gained by so doing. For some of the members of the party it was decidedly injurious, but others called for it occasionally as a refreshing drink.

"The average weight of these northern Eskimo men is one hundred and thirty-five pounds, but that of the women one hundred and eighty-eight pounds. Obesity is foreign to the Eskimo, and leanness is equally rare".

Studies of negro diet have been made for the United States Department of Agriculture (Bulletin No. 71, 1899) by H. B. Frissell and Isabel Bevier, with the following result:

The preponderance of protein in the diet of Virginia negroes as compared with those investigated in Alabama is due to residence nearer the sea and large consumption of fish, especially salt herring.

Arthur Goss (Nutrition Investigations in New Mexico, U. S. Department of Agriculture, Bulletin No. 54) gives the following dietary of a Mexican living in New Mexico and an Alabama negro:

In this dietary the Mexican subsists upon but little more than half of the standard requirement of protein, and the negro upon less than one half. The Mexican eats chiefly flour and frijoles, with little meat, and the negro subsists upon bacon, fish, and cornmeal.
