GEOGRAPHICAL DISTRIBUTION. '] 1 



opinion, and an earlier answer without unnecessary publicity would 

 have been obtained had the specimens been sent to the proper depart- 

 ment in the first instance. An early opportunity was taken to depute 

 an officer of the Geological Survey to examine the deposits, and 

 Mr. E. Yredenburg has given a report of his inspection of the mica 

 pegmatites and other minerals found in the Kishengarh State. He 

 found numerous large veins of pegmatite traversing the gneissose 

 formations, and many of them had been superficially broken in the 

 search for mica ; but the work was discontinued on account of miscon- 

 ceptions as to the mode of occurrence of the mineral. One of the 

 most promising outcrops found was about a mile south-west of Dadia, 

 and another, about a mile north of Neagaon, showed large mica-crystals 

 in a pegmatite containing beryl. Mica of good size has also been 

 obtained from pegmatites on the northern side of the road from Sanvar 

 to Nasirabad, about two miles from Sarwar. So far, marketable 

 material has not been obtained in quantity, but the veins have been 

 only superficially examined, and the outcrops appear to warrant more 

 thorough prospecting operations. 



Tonk. 



There are plates of muscovite in the Geological Museum, Calcutta, 

 measuring 5 to 6 inches across and some of them are of fair quality. 

 These have been obtained from several localities in the Chattarbhaj 

 hills, north-east of Tonk. 



Sirohi. 

 Major F. T. C. Hughes of the Errinpura Irregular Force reports 

 the occurrence cf mica near Rohera. Plates of good muscovite, 5 to 6 

 inches square, have been obtained. Major Hughes thinks there are 

 indications of the same mineral in other parts of the Sirohi State.
