SKETCH OF THE 



greyish green. It appears to be a variety of Epidote, and the rock just 

 described occurs in considerable abundance.* 



In the series of rocks under consideration, chlorite appears frequent- 

 ly to occupy the place of the hornblendes, and the rocks containing this 

 mineral have, sometimes, a structure approaching to that of gneiss, — the 

 chlorite being arranged in nearly parallel, interrupted layers, alternating 

 with layers of the other ingredients. This last rock is distinctly strati- 

 fied, and passes into chlorite schist. Chlorite also occurs in minute quan- 

 tity in many of the rocks approaching to the nature of white stone. 



In the neighbourhood of the central range, in this part of the coun- 

 try, we have numerous detached ranges, and the surface of the country, 

 on proceeding towards Ndtlidwdra, becomes rugged and uneven, exhibit- 

 ing a mammillary belt, in which are situated several deep and small val- 

 leys. The rocks observed are different modifications of granitic rocks, 

 alternating with hornblende rocks. NdtJidivdra (famous for its temple, 

 which is one of the most sacred in India, with those of the Vaishnava 

 persuasion,) stands about twenty-four miles north, and a little to the east 

 of Udayapur. It is situated on the inner slope of a group of hills of a 

 rugged aspect, and which group is connected with the mammillary belt 

 above alluded to. The rocks which occur there are argillaceous schists, 

 containing a large proportion of mica, and these pass into micaceous 

 schist, which alternates with quartz rock passing into gneiss. The 

 JBands river, skirts this group. For about four miles east of Ndtlidivdra^ 

 we have still numerous detached hills and groups, and the country is 

 broken and rugged, — we then enter the level plains of Mewar. 



* In addition to this mineral, I suspect that Schiller spar occasional'y occurs. Associated with 

 the quartz is a rock which has a specific gravity of about 2-8. It is so intimately blended with the 

 quartz, however, that I could not determine with any degree of precision respecting its nature.
