^ OF CUTCH. 3 



the Rajmahals and their representativ'es are unaccompanied by beds of 

 definite geological date, and the discovery of the relations of these rocks 

 to the cretaceous beds of Ootatoor in Trichiuopoly district. Southern 

 India, only rendered it more desirable to ascertain correctly what was 

 the connection between them and the Jurassic marine series. The 

 Cutch representatives of the latter were described at some length by 

 Captain Grant in the paper already referred to, but he left the question 

 of the relations between the Oolitic beds, which he termed the ' lamina- 

 ted series or Upper Secondary,' and the Zamia-bearing beds, his 

 ' sandstone and clay with beds of coaP somewhat obscure. It will show 

 the state of knowledge of the subject, previously to the observations 

 I am now going to describe in detail, to quote the j)assage in 

 Captain Grant's report, which treats of the relative position of the 

 'Upper Secondary formation"* (that is the beds with Jurassic fossils 

 to the other strata. Captain Grant writes*-— 



" I searched diligently to find the relative position of this forma- 

 " tion (Upper Secondary) distinctly defined, but in vain, as, at its ap- 

 " parent junction with other beds, the whole of the strata were broken 

 " up, and so confused as to bafEe every attempt to ascertain the boundary. 

 " I am induced, however, to believe that it occupies hollows in the sand- 

 " stone and coal formation, or abuts against it. It cannot underlie that 

 "series, because its strata are always horizontal, except where locally dis- 

 " turbed ; while the beds of sandstone and coal are as invariably in- 

 " clined at a considerable angle, and are everywhere intersected with 

 "•dykes, slips, and other dislocations, from which the Upper Secondary 

 " strata are generally free. In one instance, the formation evidently 

 " occupied a hollow in the coal sandstone. 



" In many places it appears to abut against the sandstone, occupy- 

 " ing large tracts which may, at some period, have been covered by beds 

 " of that formation, subsequently washed away. From what has been
