The workings at Rajmahal and Maga are not quite so extensive; but they 
occvir on the same geological horizon and were conducted in the same manner. 
All of these workings are now abandoned. 
Roci; crystal .—Rock crystals were formerly obtained from some small jn'ts 
sunk in the quartzites at Aurangpur, about 15 miles south of Delhi. The pits 
are now abandoned and fallen together, but the small crystals of quartz sjjread 
about round the pit are very numerous. Probably the rock crystal was obtained 
from some quartz vein running through the quartzites. 
Marhle .—Marble is of frequent occurrence among the Arvali rocks, and is 
extensively quarried in several places. It is generally white, but coloured marbles 
are occasionally met with, as at Kho and Raldeogarh, and black marble is found 
in the Motidongri ridge in Ulwar. 
The most extensive quarries are those of Makrana, situate on the western 
edge of the Arvali range in Jodhpore. The marble forms a long ridge running 
nearly north and south. It is nearly vertical and regularly bedded; and some 
of the beds being upwards of 2 feet in thickness, large blocks can be obtained. 
The quarries are confined to about 20 feet of the section, but extend in length 
for several hundred yards. 
Marble is also extensively quan-ied at Jheri, in CTlwar, and Raialo, in Jeypore. 
A coarse kind of marble is quarried at Sarangwa, about G miles west of 
Desuri, on the western side of the Arvali range, in Oodeyporo. 
Steatite .—The steatite or soaiJ-stone of wRich the models of the Taj and 
other ornamental carvings are made at Delhi and Agra is, I believe, quarried 
in the ridge at Mora Bhandfiri, about 12 miles north-west of Hindaun, in 
Jeypore.

In my Talchir-Karharbari flora ^ I had an opportunity to point to the 
greater resemblance of this flora to that in the Bacchus-marsh beds in Victoria, 
than to that of the Rew-castle beds, from the great abundance of the genus 
Gangamoyteris in both, and I quoted a passage from a letter of Mr. 0. S. 
Wilkinson, Government Geologist, to the late Rev. W. B. Clarke, which the 
latter had sent me for perusal, and from which it w'as ap 2 '>arent that Mr. Wilkin¬ 
son assigned to onr coal flora a higher position than that of the New-castle 
beds and lower coal-measure flora. In my notes to Mr. Clarke, which he published 
in his “ Remarks on the sedimentary formations of Rew South Wales,”^ I assigned
