2 Report on the Magnetic Survey. [No. 1. 



I am particularly happy to mention the valuable assistance which 

 I have received in every way from the Government of India. 

 I have the honour to be, 

 Sir, 

 Tour most obedient servant, 



Hermann Schlagintweit. 



1. — Routes and Geographical Remarks. 



I left Calcutta, April 5th, proceeding via Kishnagur, Dinagepore 

 and Tytaliah, to British Sikkim. My draftsman, Abdool Cawder, 

 went the same way, keeping one day's dawk distance in order to 

 make corresponding barometric and other observations. 



The assistant, Mr. Adams, went by the steamer to Caragola Ghat 

 and via Purneah to Darjiling, 



After a short stay in Darjiling and its environs, we proceeded 

 up to the ridge, which branches off from the central mass of 

 Kunchinjinga, and extends in a southerly direction, near the south- 

 ern borders of the Sikkim Himalaya. Previous official propositions 

 to the Sikkim Rajah for permission to travel in his dominions were 

 perfectly unsuccessful, though Dr. Campbell, Superintendent of 

 Darjiling, most obligingly and with true scientific interest tried 

 every way to forward my plans.* 



The range extending from Tonglo over Chundunangee, Phulloot, 

 Gosah, Singalelah to the mass of Kunchinjinga, allowed me not only 

 to make a very complete set of comparative magnetic and physical 

 observations at different heights, but these peaks commanded at

 of the Eastern Himalaya, extending 20° East from Chumalari and 

 30° West from Kunchinjinga. 



From the different points of the Singalelah range the height and 

 position of the snowy peaks were most carefully measured with an

 well as Mr. Hodgson's precious and unremitting assistance ; I take advantage, with 

 particular pleasure, of this occasion, to return my best thanks to both these 

 gentlemen. 



It is scarcely necessary to add haw much I was assisted by Dr, Hooker's pre- 

 vious researches in this part of the Himalayas.
