During his expeditions, Stein always made physical anthropological measurements. He measured cranial specifications, tribe, language etc. of the person examined, and photographed men belonging to the same ethnic group. He was especially interested in little-known races and tribes. The linguistic data collected by him was incorporated in the major volumes of the Linguistic Survey of India by G. Grierson.
