conglomerates of Broach by more recent igneous rocks. The details of 



liis observations in Guzerat were never published, and it is now impossible 



to tell what were his reasons for believing in volcanic action of later date. 



No trace of such action has been found by the present survey in the 



locality mentioned.

most of the writers already mentioned. The only 



additional remark of any importance was a very ingenious and happy 



suggestion that the ' coralline limestone,^ mentioned by so many writers 



as having been employed in the ruined buildings of Mandoo, might be the 



limestone mentioned by Captain Dangerfield as met with near Bagh on 



his journey towards Guzerat. Dr. Oldham pointed out the great interest 



attaching to this question to Captain (now

at Mundlaisur, and this officer, in November 1856, discovered fossils 



at Cherakhan about twenty-two miles east of Bagh, and recognised them as 



being of cretaceous age. A few months later, in January 1857, he 



revisited the locality in company with Mr. Blackwell, and added largely 



to the fossils collected.

 clusion that they were of Neocomian age. Unfortunately, either from 

 Dr. Carter's having misunderstood the details of the discovery, or from 

 some mistakes made by Mr. BlackweU, from whom the former appears to 

 have derived much of his information, the account given is full of errors. 

 The merit of the discovery, which was in reality solely due to Captain 

 Keatinge as above shown, was ascribed partly to Mr. Blackwell, and the
