rock, which runs along- the boundary, may contain 

 some true rej^resentative of the conglomeritic sand- 

 stone, which is developed in the outliers to 

 the south. To the north-east of Kubra hill it is 

 certainly absent, shaly beds, which pass above into 

 porcellanic ones^ being seen to rest directly on 

 the metamorphics. A few miles west of this 

 eminence, however, it comes in again, and is thence 

 seen continuously for more than 40 miles. At 

 Murye, south-east of Eamnuggur, the boundary 

 becomes of a very obscm-e nature . The conglomeritic 

 rock, which deserves the name of quartzite rather 

 than sandstone, attains a thickness of several hun- 

 dred feet in the hills, yet for about two miles west 

 of Murye not a trace of it is to be found along the 

 boundary. A fault at once suggests itself; yet 

 taking the normally uncertain development of this 

 rock into accoimt, it seems more simple to explain 

 this and some other parallel cases by local pecu- 

 liarities of deposition. The conglomeritic beds are 

 also absent where the boundaiy crosses the Sone 

 near Jhaal, but are found well developed to the 

 west of this village. 



The limestone No. 3 attains its greatest develop- 

 ment in thickness and super- 

 ficies east of the Eehund, 

 where it forms a very important member of the 

 series. To the east of Khone Khas (see fig. 3), 

 it occurs in beds 3 or 4 feet thick, of a bluish 

 color, the bottom 30 or 40 feet being very hard 

 and silicious, scarcely efiervescing with acids- The
