Vilhjalmur Stefansson, noted Arctic explorer, will speak today at 11 o'clock in Harvard 5 to the students of Anthropology 2 in a lecture open to all students in biological sciences.

Stefansson, who has lived among the Eskimos on a meat and water diet for a period of seven years, will speak on the "Effects of Meat Diet on Eskimos and White Men." Professor E.A. Hooton of the University is collaborating with Stefansson in a series of experiments to lest the effect upon health of an all meat diet.

Stefansson was a member of the University faculty from 1904-06, and has spent 11 1-2 years in the Arctic.

Since early this year Stefansson and Karsten Anderson, his assistant, have been on a meat and water diet. They will continue this diet until next winter. A committee of ten scientists and physicians is observing the results of the experiment.
