xiv PREFACE. 



and contrary to the will of the Sikkim Rajah ; who was 

 imagined to be a tributary of China, and protected by 

 that nation, and to be under no obligation to the 

 East Indian government. 



With regard to the obligations I owe to Dr. Campbell, 

 I confine myself to saying that his whole aim was to 

 promote my comfort, and to secure my success, in all 

 possible ways. Every object I had in view was as sedu- 

 lously cared for by him as by myself: I am indebted 

 to his influence with Jung Bahadoor* for the permission 

 to traverse his dominions, and to visit the Tibetan passes 

 of Nepal. His prudence and patience in negotiating 

 with the Sikkim court, enabled me to pursue my inves- 

 tigations in that country. My journal is largely indebted 

 to his varied and extensive knowledge of the people and 

 productions of these regions. 



In all numerical calculations connected with my obser- 

 vations, I received most essential aid from John Muller, 

 Esq., Accountant of the Calcutta Mint, and from his 

 brother, Charles Muller, Esq., of Patna, both ardent 

 amateurs in scientific pursuits, and who employed them- 

 selves in making meteorological observations at Dorjiling, 

 where they were recruiting constitutions impaired by the 

 performance of arduous duties in the climate of the 

 plains. I cannot sufficiently thank these gentlemen for 



* It was in Nepal that Dr. Campbell gained the friendship of Jung Bahadoor, 

 the most remarkable proof of which is the acceding to his request, and granting 

 me leave to visit the eastern parts of his dominions ; no European that I am 

 aware of, having been allowed, either before or since, to travel anywhere except to 

 and from the plains of India and valley of Katmandu, in which the capital city 

 and British residency are situated.
