OF BUNDELKHAND, 8cc. 31 



Below the lime-stone at Sdgar, is a stratum of amygdaloid, containing 

 ealc-spar, and a few zeolites, which resembles the toad-stone of England ; it 

 there reposes on sand-stone, but I have not met with it in situ in any other 

 part except some indistinct vestiges near Jysinhnagar, nor can I state, 

 upon any authority, that the position here described, is applicable else- 

 where. 



From Saugor, 1 proceeded southward, via Jysinhanagar to Tendu- 

 haira, and met with no other rock than trap (with abundance of chalce- 

 dony, semiopal, mealy zeolite, cacholong, agates, jaspers, and heliotrope 

 strewed upon it,) until I descended the range of hills which forms the 

 northern barrier of the valley of the Nermada river. 



This great valley is favourable for throwing light on the primitive 

 rocks of the central chain, where the force of receding water appears to 

 have swept away the upper, and exposed to view the lower and older 

 strata ; many inferences may hereafter be drawn from a careful examina- 

 tion of this valley, but it would be premature to hazard any conjecture at 

 present. I will, therefore, only observe, that the whole mass of overlying 

 rocks which I have just passed, reposes on red marie, or sand-stone, as is 

 apparent in the bed of the Sarana river, about one mile north-east of Ten- 

 duJcaira, and all along the foot of the hills in that direction. 



Its associate, the earthy lime-stone, here becomes a rock which general 

 ly appears half calcined ; but its property of effervescing with acids is not 

 destroyed, except in a few instances where it has become highly indurat- 

 ed ; it fuses readily with a moderate heat, and operates as a flux when 

 mixed with clay ; and in this part, it almost always contains fragments of 

 sand-stone, which are more or less changed by its contact.
