AT NAGPUR, &c. 211 



the dark (No. 2.) stripes given by which are very variously contorted. 

 Towards the left bank, granite and gneiss were formed, passing into the 

 lime-stone, the gradation from the one to the other being very gradual, 

 and showing intermediately, an intimate blending (No. 3.) of the two 

 rocks, which could only have taken place when both were in some degree 

 of fluidity. 



Before leaving Gokula, I may be allowed to notice the very numerous 

 tumuli of the neighbourhood. The rings of stone which marked them all 

 were, in some instances, as much as fifty or sixty paces in diameter; they 

 were mostly unraised, but some were elevated by a heap of stones. Dr. 

 VoYSEY noticed, that they were similar to those about the Hyderabad 

 country. The natives appeared to have no tradition concerning them, 

 nor any idea of what they were. 



Dr. V. and myself had one traversed in the centre by ditches of con- 

 siderable depth, but we did not succeed in meeting with any remains. 



The following is a part of the collection Dr. Voysey made, between 

 Nayahund and Gokula, and named for me by him : 



Slaty iron glance. 



Granite, large proportion of quartz, with specks of mica, porphyritic 

 syenitic granite, the hornblende being in large crystals. 

 Quartz, passing into chert. 

 Black mica schist. 

 White ditto ditto. 



Sand-stone, 



No. 2. In two specimens are veins of a Lead ore, or of Antimony. 

 No, 3. Lime-stone, passing into Gneiss.
