OF CENTRAL INDIA AND BENGAL. 305 



which I had the honor of laying before the Asiatic Society of Bengal 

 in May 1856,(a) I proposed for the entire group the name VINDHYAN, 

 derived from that remarkable range of high ground, called the ViN- 

 dhyan hills, which forms such a prominent feature along the northern 

 bank of the Nerbudda river. 



It was true, that for the same rocks other names had been previously 

 proposed, and especially by Dr. Carter of Bombay in his valuable " Sum- 

 mary of the Geology of India," but I endeavoured to shew, that inas- 

 much as this author had based his classification on erroneous views as to 

 the position of these rocks, and erroneous identifications of the various 

 groups, the result of adopting his name would be inevitably to lead to 

 erroneous conclusions : and that it was, therefore, desirable at once to 

 indicate the separation of this group by the adoption of a distinct and 

 separate name. I proposed to adopt the three -fold sub-division which 

 had been, already, given to the great group — and which seemed to be 

 well defined by marked physical features — and I gave to these sub- 

 divisions, names derived from the localities, where they were best seen ; 

 from the Kymore range, north of the river Sone; from the Rewah 

 district, and from the Bundair Hill. I took the opportunity at the same 

 time, of intimating the possibility that this three-fold division might 

 hereafter be reduced to a two-fold sub-division. 



This was the view urged by Mr. Medlicott, although not adopted by 

 myself. 



I desire here, publicly, to correct an error into which I was at that 

 time led, by placing too great reliance on a similarity in mineral or 

 lithological texture. I stated that the Damuda rocks (see below) rested 

 unconformably upon these Vindhyan beds. It will be seen from the 

 valuable report of Mr. Medlicott's labours (above p. 171,) that no case 

 of actual superposition of the two series has as yet been seen ; 

 although from other evidence he perfectly agrees with me in the views
