cherry. The sand-stone of Trivacery is absolutely identical in all 

 petrographical characters with many specimens from the ISTagpore 

 territory ; it also contained many fossil trees, which I am convinced 

 will prove the same as those found in some places of the JNagpore 

 territory, as well as near Eaneegunge to the west of Burdwan and 

 Calcutta. 



I think that the coal-bearing strata of Eaneegunge, in the hills 

 west of Calcutta, belong to the same formation with the rest of 

 the above quoted localities. ' 



"Whether the lime-stone and shales of Kulladghee, which I had 

 occasion to investigate in the cold season of 1854-55, constitute a 

 formation diiferent from the above or not, I am unable to say at 

 present, from want of my journals and specimens, which have been 

 all sent away. 



The character of this extensive formation of sand-stones and 

 shales varies considerably ; generally the sand-stones can be well 

 distinguished from the underlying shales. 



In some localities the distinct stratification is clearly visible, and 

 the sand-stones, more or less horizontal, repose contrary to the 

 ordinary laws of conformity, upon the out-crop of the inclined 

 shales underneath : this is the case in the Grwalior territory, in 

 Bangapilly, Cuddapah, &c. 



In other districts, for instance at Nagpore, near Chanda, and 

 on the Pranheeta, the marly slates and sandstone seem to lie 

 conformably, and have both been subject apparently to the same 

 bendings and foldings. 



But though the characters of the rock are very variable, it is 

 nearly always possible to trace the one variety into the other; 

 occasionally the mere lithological resemblance, even between very 

 distant points of the formation, is very striking. 



Fossil remains have been found in several places; the best 

 known locality is at present the Nagpore territory, where the per- 

 severing researches of the Beverend E. Hislop have brought to 

 light a rich collection of fossil plants and several very interesting 

 animal remains. 



I have much pleasure in acknowledging my obligations to'Mr.
