Colonel L. A. Waddell (http://en.wikipedia.org/wiki/Laurence_Waddell)
collected 32 skulls in the South-Western and Eastern district of
Tibet.

The collection can be divided into two groups. The first, type A,
comprises 17 skulls, which came from graves in Sikkim and neighbouring
areas of Tibet. The remaining 15 skulls, type B, were picked up on a
battlefield in the Lhasa district and were believed to be those of
native soldiers from the Eastern province of Khams.

These skulls were of particular interest because it was thought at the
time that Tibetans from Khams might be survivors of a particular
fundamental human type, unrelated to the Mongolian and Indian types
which surrounded them.

These data consist of five measurments made on each skull, together
with an indicator skull type. The firve measuments (all in
millimeters) are as follows:
 X1 - Greatest length of skull.
 X2 - Greatest horizontal breadth of skull.
 X3 - Height of skull.
 X4 - Upper face height.
 X5 - Face breadth, between outermost points of cheek bones.

The original source gives 45 other measurements on each skull!
