SKETCH OF THE 



which, betwixt two hand specimens from the different beds, and the above 

 difference is observed over a square surface of several yards. It would 

 be difficult indeed to believe the two different causes had operated in 

 forming these (different beds of rock. 



That granite does occur oftener in an unstratified than a stratified 

 form I am free to confess. This is particularly the case in the well- 

 marked varieties. It also exists in long-regular-prismatic beds — inter- 

 posed among other stratified rocks, and alternating with them. These 

 beds are certainly not subdivided into strata, but may not this have been 

 owing to a particular arrangement of the constituent parts, and does not 

 the circumstance of their alternating with other strata, and the regular 

 prismatic form of the beds, indicate a stratiform structure, or at least some- 

 thing very analogous to it. I stated in a former paper, that I considered 

 the granite which forms the small hills protruding through the deluvium 

 of Guzerat at Pandua, to the north of Balasitiore, as belonging to a very 

 old variety, and the out-croppings of a similar formation may, very pro- 

 bably, be discovered in many of the granites of this district. The talcose 

 and chloritic granites, which form the protogine of Jurine, the last men- 

 tioned Geologist considers very antique varieties. These occasionally 

 make their appearance here ; but, without speculating farther on this very 

 difficult subject, I shall proceed to enumerate very briefly the different 

 rocks which occur in the southern portion of the district under consi- 

 deration. 



I have, on a former occasion, given a section of the strata on the 

 route from Baroda to Udayapur, and this, in addition to Captain Dan- 

 gerfield's account, and the section of Captain Stewart, in the Bombay 

 Literary Transactions, renders it unnecessary for me to say much on 

 this branch of my subject.
