to decomposition of the gneiss, by which it is immediately 
followed, and which continues to the bottom of the well. 
From the summit of the hill of Seetabuldee, the differ- 
ence in the outline of the rocks eastward is very perceptible. 
The flattened summits, and long flat outline, with the 
numerous gaps of the trap-hills, are exchanged for the 
ridgy, peaked, sharp, outline of the primary rocks *. At 
Ramteak and its vicinity, the rocks are of granite and 
gneiss. At Doonguree, at Pullorah and Parsoonee, are 
found crystallised marbles passing into gneiss, capable of 
receiving a fine polish. " FoHated black manganese ore,'' 
in large quantity, is found here (Jameson's Mineralogy, 
third edition) : some of the marbles contain a small quan- 
tity of magnesia. At Khoraree, a dolomite, or magnesian 
marble, is found, also in gneiss. At Nyakoond Pasonee, 
bed of the Pesh, granite and gneiss of various kinds, quartz- 
rock, and sandstone, occur. 
P.S. I have lately had an opportunity of fusing a large 
piece of the Seetabuldee basalt in a steel-furnace. The pro- 
duct, after an hour's fusion, was a fine black opake stone, 
resembling porous obsidian. Glass-bottles are commonly 
made in the Mediterranean from basalt, and that of Seeta- 
buldee seems to be of an equally favourable nature for that 
purpose. 
• Captain Bayley's plates of the battle of Seetabuldee give a very cor- 
rect idea of the first outline of the basaltic trap-hills at Nagpoor.
