Cecil Champain Lowis, The Tribes of Burma — The Kachins (1910)
“ Wehrli gives 145 works of reference more or less utilized by him in the preparation of his scholarly monograph published at Leiden in 1904. A large number of these deal with the Singphos of Assam. The most important of the references to the Ching-paw proper of Burma are given in the bibliographical note printed on page 70. ”
