1836.] the Country between Hyderabad and Ndgpur. 121 



From the summit of this volcanic rock the "basaltic hill of Sitabuldee 

 and others are seen to the south and west ; and at the same distance 

 to the north, the rounded mica slate and granitic hills of Ramtesk, 

 which extend into the Bengal territory south of Sagur. 



An examination of the map will impress more strongly, than any 

 thing I can urge, the importance of examining the whole Sichel or 

 Shesha range, from the great lake water of Lonar, (to which the atten- 

 tion of your readers was called in the number of Journal for June, 

 1 834,) to the fossil beds of the Nirmul hills ; and from thence to Bibbery, 

 the fossiliferous localities above Mungapett, and the hot springs of 

 Byorah and Badrachellam. Other hot springs are also said to be 

 found in the Nirmul range, regarding which I could get no correct 

 information. 



There are three other points to which it may he well to call the 

 attention of such of your readers as may have an opportunity of visit- 

 ing these localities. 



1st. Whether the Sichel hills really terminate about Mungapett, 

 or are continued injjroken ranges towards Rajamundry ? I have long 

 considered it probable that the dykes so common in the Circars are 

 connected with the great basaltic ranges which cross the Deccan in 

 nearly the same direction ; and Dr. Benza has recently discovered a 

 bed of marine fossils on the top of a basaltic hill five miles south of 

 Rajamundry, and a little above the alluvial plains of the mouths of the 

 Godavery. 



2nd. Whether the basaltic hills near the Manjerah river, on which 

 Dr. Voysey discovered fossils, are connected with those of Bekanur- 

 pettah and Nugger above described ; and whether they belong to the 

 same geological period as the Ni'rmul hills ? 



3rd. I entertain little doubt that the basaltic formation of the valley 

 of Berar and the basin of the Panah river, which falls into the Tapti, 

 belongs to the period of eruption which elevated the Nirmul fossils 

 from the bed of the sea ; before, however, coming to this conclusion, 

 with reference to the northern part of the valley, the connection be- 

 tween the localities of the Nirmul and Chiknee fossils with those of 

 the Gawilgurh hills (A. R. vol. 1 7th) must be ascertained. 



4th. The exact relations of the crater of Lonar to the great volcanic 

 district to the N. W. where fossils have not yet been met with. 



But as the difficulties opposed to the investigation of the greater 

 part of such wild and unhealthy tracts will probably prevent these 

 desiderata being soon supplied ; I hope that a sufficient number of orga- 

 nic remains have been obtained from the central point of the district, 

 to enable an experienced geologist to arrive at a tolerably correct esti-
