 He assembled a list of Tibetan noble families and, along with his wife, established biographical notes about a number of refugees (most notably about women who practised polyandry, "something really at variance with our way of conducting family affairs"), and described Tibetan Muslims.Having registered their songs, sagas, everyday conversations, oracle prophecies and religious ceremonies, Peter took more than 3,000 photographs of Tibetans.When he asked them if they had body hair (an important piece of information in anthropology), the relatively hairless Tibetans roared with laughter.
