PREFA CE. 
Britten, late of the Kew Herbarium and now of the 
British Museum, gave very great assistance in identi- 
fying specimens of Plants ; he also kindly under- 
took to revise the proof sheets of the botanical 
portion of the work. The identifications and de- 
scriptions of Algse, JDiatomacese, &c., as also the 
drawings of these, are by Dr. Dickie of Aberdeen, 
Mr. Fitch having lithographed the drawings. 
The Ornithological portion of the work has been 
edited by Mr. E. B. Sharpe, and Mr. H. W. Bates has 
exercised a general supervision over the work, whilst 
it was passing through the press. The analysis of 
the water of the Pangong Lake was kindly under- 
taken by Dr. Prankland, and is published with his 
permission. Mr. Etheridge, of the Eoyal School of 
Mines, kindly identified the only fossil which was 
found in Yarkand territory, and his prognostication 
that coal would probably be found in Yarkand has 
already turned out to be true, for Mr. Shaw has 
informed Dr. Henderson that specimens of coal have 
since been obtained in Yarkand territory. 
Mr. Scott, of the Board of Trade Meteorological 
Office, kindly allowed the observations of the baro- 
meter, boiling-point thermometer, and the wet and 
dry bulb thermometer to be worked out in his 
office. 
The Map was drawn by Mr. Oulet at the Eoyal 
Geographical Society's rooms, under the supervision 
of Mr. Bates. 
The Plates which illustrate the Narrative, if not 
all works of art, have at least this recommendation
