Abstract
IN the course of an expedition to Lake Titicaca, South America, financed by the Percy Slade Trustees in which one of us (H. P. M.) took part, an interesting observation was made in regard to the diet of the Quetchua Indians on the Capachica Peninsula near Puno. These people are almost certainly descendants of the Incas and at the present time live very primitively. They exist largely on a vegetable diet of which potatoes form an important part. Immediately before being eaten, the potatoes are dipped into an aqueous suspension of clay, a procedure which is said to prevent ‘souring of the stomach’.
