Abstract

A field study was made of the Eskimos of the lower Kuskokwim River area, in the southwestern region of Alaska, the home of the most primitive of the American Eskimos. This region was chosen because of the opportunity afforded to observe both primitive and semicivilized natives. Many of the settlements are so isolated that contact with the white man and particularly with his foods has not been sufficient to effect any sign of dental caries. In a few settlements, on the other hand, where traders have brought in "store" foods, the natives show an exceedingly high incidence of caries. In 1935 we (L. W. and D. W.) showed that 85 per cent of the mouths free from caries contained no lactobacilli.1 In 1936

Rosebury and L. M. Waugh,2 in a similar series of experiments, found that 86.4 per cent of the mouths free from caries showed no lactobacilli
