 Having thus described the Vindhyans in detail, it remains to discuss 

 some points connected with them as a whole. As may have been surmised 

 from the foregoing-, the total thickness varies much in different parts of 

 THckness of Vind- *^^ ^^^^ partly from original conditions of deposi- 

 ^^^''^' tion, and partly from the effects of subsequent denu- 

 dation. In the extreme east towards Rotasgurh we have about as follows :

Kymores ... ... ... ... ... ... 1,300 



3,300 

 In the neighbourhood of Rewah, the fall thickness of the upper 



Vindhyans is perhaps about 2,500 feet. At Kuttungee, where the lower 

 series is extinct, the thickness of the upper is about thus —

Upper Bundairs ... ... ... ... ,.. 650

 From this point westwards the formation thickens rapidly, and at 



Hoshungabad the following may be taken as an approximation : —

 while in the Dhar forest the full amount has been estimated at some 



10,000 feet. In the Gwahor country, a section north-west from Sipri, 

 would be about as follows : — j^gg^^
