[No. 135. 



To Captain Mackeson, Political Agent at Peshawur, we beg also to re- 

 turn our best thanks, for procuring for us, through General Avitabile, 

 protection from the Cohat chiefs, and for his hospitable reception on 

 our arrival at Peshawur. 



(Signed,) W. Jameson, 

 Ambala, 28th June, 1842. On Deputation on the Indus. 



Barometrical Observations taken to ascertain the Altitude of the Sta- 

 tion of Purulia, in the Ramghur District. By Capt. Hannyng- 

 ton, 24th N. I. 1st Assistant to the Governor General's Agent, 

 Maunbhoom. 



In collecting the various documents relative to the Storm of 2nd and 3rd June 

 1842, which form the subject of my Seventh Memoir, 1 had occasion to solicit from 

 Captain Hannyngton, to render his valuable report fully available for my purpose, 

 the Barometrical correction for the difference of altitudes, and to obtain this more 

 correctly, he requested me to obtain for him from Major Bedford, of the Surveyor 

 General's Office, synchronous observations. 



As every point of which the altitude can be thus determined, forms a valuable 

 addition to our knowledge of the physical geography of India, 1 have requested 

 Capt. H. to allow me to publish his results, which he modestly wished me to do in 

 a foot note ; but as it would much resemble putting a thing in the place least likely 

 for it to be found when wanted, I have taken the liberty of making a separate, 

 though brief, article of the observations, with his remarks. — H. Piddington. 



The observations duly corrected were as follows :
