1836-3 the Country between Hyderabad and Ndgpur. 97 



they appear universally to rest ; I am induced, contrary to my former 

 intention, to take to England with me, those specimens of which 

 there are no duplicates. The separation of the collection would greatly 

 lessen its value, by depriving me of the opportunity of comparing, 

 with each other, and with arranged collections, the fragments of those 

 of which duplicates were not preserved, and of thus restoring the 

 fossils of which no perfect specimen was found. A selection of the 

 most perfect were, also, sent to Mr. Lyell, but as he considers it 

 requisite that numerous species should be ascertained previous to 

 arriving at any conclusion as to the age of the fossiliferous rocks, it 

 may be for the advantage of Indian geology, to submit the rest of the 

 specimens to him ; and on the characters being determined, to return 

 a portion of them to India. There are, however, a sufficient number 

 of duplicates to illustrate the outlines of the geology of the interesting 

 tract of country referred to, and to connect the singular phenomena 

 observed, with others, to the west and east of the route, and in the 

 countries of the peninsula to the south, and the Bengal provinces to 

 the north. The outline map includes several places, inserted in the 

 plans published along with Dr. Voysey's papers and Captain Jenkin's 

 Account of the Mineralogy of Nagpur, p. 199, of the 18th volume of 

 the Asiatic Researches ; the interval between which, it will assist in 

 filling up. I shall seldom use mineralogical terms, except I have had 

 an opportunity of comparing the specimens with those collected by 

 persons well acquainted with the science ; and when they do occur, 

 an examination of the specimens will afford the means of correcting 

 any errors that may be fallen into. The geological relations of the 

 strata were ascertained with as much care as the nature of the country 

 permitted, and no exertion was spared in tracing them as far as pos- 

 sible, both on the plains, at the foot of the hills, and their most 

 inaccessible summits. My avocations however were unfavourable, and 

 a person more at leisure would find an ample field to reward his labours. 

 He must, however, be prepared to pursue his examinations in the height 

 of the hot season, when the grass and wood jungle are less luxuriant, 

 and the plains free from their covering oijawdri and other grain. 



Some account has already been published* of the country between 

 Masulipatam and Hyderabad, on which I had not an opportunity of 

 making many observations. One or two points, however, deserve to 

 be noticed, as the specimens collected in this part of the route are 

 similar to those found north of Hyderabad as far as Nirmal, and throw 

 some light on appearances on which important inferences have been 

 too hastily founded.
