we can hardly suppose that in two different but neighbouring districts two 

 distinct cleavages should have been produced in one set of rocks, each' 

 exactly parallel to the previously existing gneiss lamination in the dis- 

 trict. It is far more probable that they would be parallel to each other. 

 At the same time it is quite possible that the metamorphics may be 



in great part at least an older formation than the

Bijawurs may have been locally metamorphosed. 



All these questions await further explanation. They are mentioned here 

 because in the examination of these beds they have frequently been pre- 

 sented by the various phenomena observed, and even this imperfect discus- 

 sion may be of aid to others similarly engaged elsewhere, but who observe 

 other characters of the rocks or see similar characters under different 

 circumstances.

although somewhat similar in general character 



and state of semi-metamorphism to the Bijawurs, differ so greatly in 

 their mineral composition that it appears probable they must belong to 

 a distinct group of rocks. They do not contain any of the rocks so cha- 

 racteristic of the Bijawur series while their own

 means clear whether, if distinct, they are higher or 

 lower in the general series ; they vary greatly in the extent to which they 

 are metamorphosed, and they are, in the area examined, entirely isolated; 

 very probably they do not differ greatly in age from the Bijawurs.
