In
order to determine the efects, if any, of the dietary habits of these natives, the data, as stated, were divided into two
groups, namely, (a) those obtained in Hudson Bay and Strait amongst natives who live, to an appreciable extent, upon mixed diets, and (b) those obtained in Baffin and Devon Islands amongst natives whose diets, except for about 2 months in the year, consist of the natural foods of their environment (
seal, whale, narwhal, walrus, etc.).
