their appearance. A little further on merely different beds of the upper 

 Bundairs are brought in contact, and the fault gradually becomes no 

 longer traceable. 



The ridge at Futtipur-Sikri has been previously alluded to, in which 

 the strata dip south-east at about 30°. It is continued south-westwards 

 as far as Kerowli, but the inclination varies greatly, being vertical at Rood- 

 awul, 5° — 20° at Byana, and nearly vertical again south of Hindoun. 



Little is known as yet respecting the upper Bundairs further to 

 west, but they have not been found beyond the Bunass in any of the 

 ground hitherto examined. Future work, however, over larger areas, may 

 prove that they extend in that direction as far as the other members of 

 the series*
