The accompanying diagrammatic section (Plate III) shows the 

 relations of the beds forming it, as they appear to me after much 

 careful study. Of the inversion of the eastern side of the synclinal there 

 cannot be the least doubt. It only affects the beds in the central part 

 of the ellipsoid, and both to the north and south of the line of section 

 they re-acquire a normal position. The position of this section is of 

 the greatest possible assistance in studying the structure of the four 

 divisions of the Sandur ellipsoid, for it allows of an approximately 

 exact correlation of the members of the series in a north-westerly and 

 south-easterly direction. In the descriptions of the sections worked 

 out in other parts of the ellipsoid, some at least of the beds can now 

 be referred to this type section with a degree of certainty which can 

 rarely be attained in dealing with a great series of much disturbed 

 formations which have undergone much regional metamorphism. 

 Several of the sections in the several divisions of the Sandur hill mass 

 are deserving of separate study and comparison amongst themselves 

 and with the standard section just described : they will therefore be 

 taken in the order in which the four divisions have been placed above 

 (page 90). 



A. — The Raman Drug, or North-Western Division. 

 This is by far the best known, generally, of the four divisions of the 

 Sandur area from the fact that on it stands the well-known military 

 sanitarium of the same name which is reached by three excellent ghat 

 roads — two on the north-eastern side of the ridge from Hospet and 

 Sandur respectively, and one on the western side leading down to 

 Narayandeverkerra (Naraindaver Kerra). In shape it is a very
