appearance of having been freshly quarried were found collected near the 

 spot as if with the intention of improving the road. 



In the same layers with these bones, and having a somewhat wider 

 vertical range than where previously observed, the same large thick-ribbed 

 shell as was found near the Ismail Khel river again occurs, but in 

 equally bad preservation. 



Fossil exogenous (?) timber is also met with, sometimes in the lowest 



beds, sometimes higher up in the series, as in the 

 dossil timber. r ,

ot the lower rocks of this series are more largely 



displayed on the flanks of most of the hills, the difference between them 



and the newer beds of the sandstone series becomes very marked, the 



deep purple colour of the strong sandstones and the brighter red of the 



clay zones being very conspicuous, while to make the contrast stronger, 



thick zones of very green glauconitic-looking sandstone frequently 



occur among these lower rocks. 



The contact of these lower tertiary sandstones with the nummulitic 



Their contact with the limestone presents here no appearance of unconform-

to the limestone being highly calcareous, and containing numerous small 

 nodules of brown haematite (as also observed beneath the limestone cap 

 north of Kureerosum, (see page 94.) 



It had long been suspected from the many slight differences observed 

 in the various junctions of these groups that the newer one certainly, and 

 possibly the older one also, followed no rigid and unvarying succession 

 in detail, but that more naturally they were subject to a certain 

 amount of lateral change, not, however, sufficient to remove or conceal 

 their distinctive general characters. An instance in point occurs here,
