of Mandoo had been built. I took the opportunity of pointing 

 out the extreme interest attaching to this limestone in a geological 

 point of view, and the utter ignorance under which we 

 rested as to its age or relations. It had been very ingeniously, 

 and correctly inferred by Dr. Carter, in his carefully com- 

 piled "Summary of the Geology of India," that this limestone 

 used at Mandoo had been derived from near Baug or Bagh, which 

 inference I pointed out to Captain Keatinge in Dr. Carter's paper, 

 telling him at the same time my own impression that it would prove 

 to be, not oolitic, as provisionally supposed by Dr. Carter, but of the 

 nummulitic age. I strongly urged Captain Keatinge to visit the 

 locality indicated, and to collect any fossils that might be found, 

 feeling confident, that it would yield a rich harvest of many forms 

 other than corals. I felt sure that it was only requisite to point 

 out to this enlightened officer, the interest of the enquiry, to secure 

 his zealous co-operation. Nor was I disappointed. In a letter 

 dated Nov. 4th, 1856, after stating that he had been prevented 

 from getting out much sooner, as he had intended, he says : " I 

 started West, without, however, the least idea of where I was going 

 to. I got out 20 miles to Kala Bowli all well. I mounted at i to 1 

 V . M., to go to Cheera Khan, which name sounded well. It was 

 distant 8, 10, 5, 14 coss, as you pleased. Early in the afternoon I 

 got it down to 3 coss, but alas I rode until after dark, and it was 

 still 3 coss, and is 3 coss now I believe, at least I never get any 

 nearer. * * * I talked to the Bheels about black stone, until I suc- 

 ceeded in making them say that I should find white, which consoled 

 me much. * # * * From the information I got I started the next 

 morning in a S. W. direction for Deola, on the Maan river. After 

 going a coss I saw the limestone in the bed of a nullah, and in a 

 coss more I was in the midst of it. Where I was (near Deola) the 

 limestone lay in a valley about a mile broad. N. and S. the coun- 

 try was all hilly, the top of the hills covered with trap ; and the bed 

 of the Maan trap. I could make nothing of the general geological 

 arrangement. In the valley the limestone was horizontal, on the 

 hill sides it always seemed to slope down hill, but it may have been 

 merely that the slabs had fallen one over the other. But the fact 

 is, I had only two days to work in, and occupied them in collecting 

 fossils.
