Effect of a local cold stress on peripheral temperatures of Inuit, Oriental, and Caucasian subjects
Male subjects comprised of six Inuit from Igloolik, N.W.T., and five Orientals and six Caucasians from Toronto, Ont., volunteered for tests to determine the effect of localized cold stress on peripheral temperatures. In each subject, skin temperatures of the right index finger, the arm, and the chee...
