In the immediate vicinity a very gneissose schist is found, closely 

 resembling this pseudo-laminated syenite in parts, although on the whole 

 an unequivocally bedded rock. 



In the Sher Nuddi near Sehora, a similar gneissose schist occurs, 



characterized by red felspar, and in places retain-

ing but very feeble indications of its bedded 



structure. In this place although there may have been an intrusion of a 



molten rock to a comparatively small extent, yet the general character 



of the mass is proved, by the recurrence of layers of different mineral 



character, to be bedded, and lamination is developed as well in the most 



highly crystalline portions as in those where the sedimentary character 



is most clearly seen. 



The presence of fragments of all these remarkable pink felspar rocks,

central India. The same fact was noticed by the Messrs. Blanford in 



Cuttack.* 



The pegmatite above mentioned is unequivocally part of the granitic 



rocks of the country, and is, as has been asserted of the group generally, 



anterior in formation to the deposition of the lowest section of those 



sandstones and shales, included under the names 



Pegmatite ofFagpur. .

 between these formations, for Mr. Hislop, speaking of the " Pegmatite

 Vol. xi. p. 381) "that it has upheaved the very highest member of

 perhaps Mahadeva sandstone of our classification, The complicated
