98 Report on the P?*ogress of the Magnetic Survey. [No. 2. 



to the districts of Pondieherry, South Arcot, and Trichinopoly, to 

 examine the interesting cretaceous strata, which yielded a consi- 

 derable Dumber of fossil remains from different localities. 



From Trichinopoly I went up by the Coonoor Ghaut to the JNeil- 

 gherries, where I stayed from the 10th to the 17th of March. 



I returned vid Mysore and Bangalore to Madras ; I left Madras 

 for Calcutta by Steamer on the 1st of April, and I reached Simla 

 on the 26th of April. 



I was accompanied during the operations of this cold season by 

 my draftsman, Eleazar Daniel, a guide in the Quarter Master 

 General's Department, and I beg to bring to the notice of Govern- 

 ment the very useful services rendered to me by this man in the 

 prosecution of my researches, both during this season and previous- 

 ly in the Himalayas, and on the march from Bombay to Madras 

 in 1855. 



The geological and paleontological collection made during this 

 season (eighteen boxes) have been forwarded to England through 

 the Government of Madras.

 Complete magnetic observations have been made on the following 

 Stations : —

Saugor. 



Dumoh. 



Jubbulpore. 



Nagri, South of Nagpore. 



Bibberi, between Chandra and Badrachellum (Magnetic

Cocanada (Declination only.) 

 Pondieherry (Dip only.) 

 Ootatoor, near Trichinopoly. 

 Ootacamund on the Neilgherry Hills. 

 Bangalore (Dip only.) 

 At Madras, the magnetic force of my needles was compared 

 with the magnets of the Observatory ; my needles were the same 

 which had been compared with the Observatory needles in February
