AUTHOR'S NOTE
PROFESSOR JAMKS WARD, of Cambridge, did
me the* honour to road through the original manu-
script of this book. As a result., 1 rewrote it. Any
merit winch may thereby have crept; into it, is due to
Ills teaching; those faults which still remain are due
to my lack of learning. The debt 1 owe him will long
remain unpaid.
The spelling of Chinese place-names is that used by
General if. R. Davies in his map of Yun-nan. (Wade's
system.) The spelling of Tibetan places which I visited
is transliterated, as accurately as possible., from the
Tibetan; for places which I did not visit, I have
adopted Mr. Eric Teichman's spelling.
My thanks are especially due to my wife who under-
took the laborious and uninteresting task of compiling
the index:.
