It is evident from this, that we have in every thing essential an 

 Parallelism evidently exact parallelism between the Nagpur and 

 ^''•*- Talcheer fields. 



The fossils of the Nag-pur field are probably identical with those of 

 the Talcheer strata. They contain certainly the 

 same genera, viz., glossopteris, pecopteris, verte- 

 braria, &c. 



The mineral character and the order of super- 

 position in both series are precisely the same.
