situations — it is sometimes soft and friable, at others it is more crystal- 

 line — it occupies the highest situations as well as the lowest. This for- 

 mation appears to me to be one of great importance, and, if examined on 

 a large scale and described with minuteness might lead to very interest- 

 ing results. When it rests upon the softer rocks, as clay slate, it is fre- 

 quently seen penetrating into their substance, the water which held it in 

 solution having percolated through the strata and deposited the lime in 

 the form of calcareous spar in their interestices, so that these rocks at 

 their surface are almost entirely converted into a calcareous rock, inat- 

 tention to this circumstances may sometimes lead into error. Iron pyrites 

 is very generally distributed through the mass, and rounded portions of 

 various rocks are found imbedded in it. 



We next proceeded to Gingla, a small village, twelve miles north 

 west of Salumbhar. On leaving the latter town, the country becomes very 

 rocky and uneven, and exhibits the mamillary aspect so often alluded to. 

 On the left hand the Dhdbar range was seen stretching north-west and 

 south-east, and other range of lower hills, running in the same direction, 

 was seen on the right. These hills are generally ridge-shaped, some 

 times peaked, and at others conical. The Dhdbar lake was seen wash- 

 ing the base of the rough and craggy hills on the left. For the first half 

 of this march gneiss passing into granite, generally of a red colour, with 

 occasional beds of hornblende slate and quartz, was seen. The hornblende 

 rocks then preponderated, and these and the granite rocks formed fre- 

 quent alternations. Gingla is situated on a hill, composed of hornblende 

 slate passing into greenstone, and in the neighbourhood are a number of 

 small hills composed of a similar rock. The soil where these rocks occur is 

 I of a red colour, derived from iron which exists in them in great abundance, 

 and the surface of the strata is covered with a thin brown crust, (carbonate 

 |$>f iron,) derived from a similar source. Occasional beds of gneiss,
