110 Report of the Magnetic Survey of India. [No. 2. 



We beg finally to state the great obligations we are under to Mr. 

 Batten, the Commissioner, and to Captain Banisay, the Assistant 

 Commissioner, of Kumaon, who did every thing in their power to 

 assist the progress of our researches in the Himalayas, and who 

 kindly procured for us every where the men best able to give us all 

 the necessary information about the country. 



Physical Geography and Meteorology. — Magnetic Observations. 



1st. — Complete Magnetic Stations have been made at — 



1. Benares. 



2. JNynee Tal. 



3. Milum in Johar. 



4. On the Sutlej near its confluence with the Gyungal Biver, 



where only the Magnetic Dip and Declination could be 

 determined. 



5. Mana in Grurhwal above Badrinath. 



6. JSFelong (declination only). 



7. Ussila, near the origin of the Tonse Biver. 



8. Mussoorie. 



We may be excused for not entering at present into any detail of 

 the result of the Magnetic observations themselves, since we are 

 anxious, before giving the general results of these observations, to 

 compare our data with the corresponding observations made by our 

 brother, Hermann Schlagintweit, in the Himalayas of Sikkim, in 

 the Khasia Hills, and in Assam. 



The necessary calculations and reductions will, however, be com- 

 pleted in a short time, and we shall have the honor to submit to 

 Government, as soon as practicable a full comparative account of 

 the whole of these observations. 



Barometric and Hypsometric observations. 



2nd. We have been able to make during the whole of our journey 

 continuous observations of the Barometer and of our delicate Hyp^ 

 someters or boiling point Thermometers, 



Our two Hypsometers have arrived quite safely at Mussoorie. Of 

 the Barometers which are very difficult} to carry during a long time over 

 a mountainous country, one by Adie, of LondoD, arrived in perfectly
