 works were reported to have existed. At this point were seen —

The difference between these two small portions of the series shows 

 how these beds are liable to vary and how little their detailed character 

 is to be depended upon, their identification in the absence of fossils 

 being only determinable from general features. 



Eound the head of the glen, faulted against the nummulitic lime- 

 stone by an east and west fracture not far from the main fault, and 

 also reappearing among the hills of the nummulitic country between 

 this and Uchali, the white and red, sandy and argillaceous, Jurassic beds 

 may be seen cropping out from beneath the whiter nummulitic lime- 

 stones, and they also appear along the main Jalar fault southward of the 

 last-named village. The triassic beds below are also occasionally visiblcc
