114 Notes on Geological Specimens from [Feb. 



which, some way below, is agglutinated by lime into a tolerablv hard 

 rock. The sand is derived from a quartoze sandstone, which crops out 

 in two or three places from the ascent south of the spring. The strata 

 are not horizontal, but neither the dip nor line of bearing could be 

 observed. 



North of Urjuna the rock is concealed by the soil as far as the 

 Pindee ghat, nearly a mile distant, which passes over the steep low 

 range, in which the Lingtee nulla rises. Its top is rounded, but on 

 either hand, several conical summits are seen outlving from the range, 

 which extends for some way from N. W. to S. E. On leaving the 

 plain of Urjuna, the blue limestone disappears, and the hill is found 

 to be composed of the usual black concentric basalt, the nuclei of which 

 are exceedingly hard, and contain much olivine : they are imbedded in 

 a soft grev or greenish wacken. I was surprised to find the road and 

 a ravine descending from the hill strewed with the limestone I had left 

 below, and did not quite credit the guide, who pointed to the top of 

 the hill as the locality from which they came. I, however, soon came 

 to it in situ, in its characteristic large smooth slabs, which render it so 

 ditncult to pass on horseback. They were observed to be slightly 

 convex upwards, to be very much fissured in various directions, and if 

 taken in the mass, to have a slight anticlinal dip, although on the top 

 the slabs were horizontal and several places remarkably altered, as 

 if thev had been half fused ; the argillaceous and siliceous matters hav- 

 ing arranged themselves into beautiful streaks of a pale blue enamel, 

 passing into calcedony, or crystallized in minute prisms. Some parts 

 of these strata had acquired a deep black color, and a flinty hardness. 

 On descending the hill on the opposite side, the same appearances 

 presented themselves, and left no doubt of the limestone having been 

 raised from its connections by the intrusion of the basalt, which had 

 slightlv bent the strata, and in doing so, had caused the numerous fis- 

 sures, and the alteration of structure. North of the Pindee ghat, 

 there are a number of very low rising grounds, flat on the top, and 

 composed of black globular trap rocks : and on the valleys, many large 

 coarse masses of calcedony are scattered ; of which, on a slight exa- 

 mination, I saw none in the hills. Near this, tha limestone, No. 97, 

 was found in the bed of a nulla. A little further on, there are two 

 verv black conical hills of trap, and at their feet, great fragments of 

 rock crystal, but of no beauty, and having cavities lined with calce- 

 donv. From hence to Kair, the country is more level, rising however 

 a little, to the right of tha road ; and four miles from the Pindee 

 ghat, and the same distance from Kair, I found the sandstone, Nos. 99 

 and 100. It was only seen in a small nulla where its strata appeared
