SKETCH 



OF THE 



GEOLOGY OF CENTRAL INDIA, 



EXCLUSIVE OF MALWA. 



By JAMES HARDIE, Esq. 



READ THE 8th OF APRIL, 1829. 



In the following Communications I have endeavoured to convey a general 

 idea of the Geology of Central India, in the hope that, as opportunities 

 occur, I shall be enabled to fill up the slight sketch now offered, by mi- 

 nuter descriptions of individual portions of this extensive tract of country. 



Nomenclature adopted in this paper. — Before describing the rocks of 

 this district, it will be as well, to prevent confusion, that I should explain 

 the nomenclature which I have adopted. — A looseness in this respect has 

 been an endless source of confusion in the science of Geology, many 

 different names being applied to the same rock by different observers, and 

 it is greatly to be wished that some specific plan should be had recourse 

 to. As the case now stands, I shall simply endeavour to make myself 

 understood.
