white yellow and bright orange crust, in feel like the white sugar on an old cake, a 

 slight crust outside but not inside. I will send specimens of it, and if I have time 

 a paper describing them more fully. 



" I forgot to mention that Meer Nusseer Khan had tried to turn the sulphur at 

 Luckee to account, and expended a considerable sum of money in the attempt, 

 but only got a few maunds of sulphur, the natives say, for the large sum of money 

 expended ; but that might have been owing to the faulty system adopted. You will 

 be enabled to judge the true percentage when the specimens reach you." 



We have to acknowledge the receipt from Government of a copy of the Revenue 

 Survey map of the Midnapore District and of a skeleton map of the Hajeepore and 

 Balagutch Dearuhs, Zillah Patna. 



From Mr. J. Weaver, of Cossitollah, we have received a very beautiful specimen 

 of iron spar (carbonate of iron), shewing the crystallisation and the rough spar, with 

 its appearance as an ornamental material. 



Examination of an ore of Cerium from Southern India by Captain J. T. Neivbold, 

 Assistant Commissioner, Kurnool, Madras Territory. By H. Piddington, Cura- 

 tor Museum Economic Geology. 



This ore was found by Captain Newbold in the central range of the Eastern 

 Ghauts, between Curnum in Cuddapah and Gogarpilly in Kurnool, a little south of 

 the Nundi Cunnama pass ; he describes it — and I give his description first as being 

 that of an accurate and experienced observer, and as conveying the impression it 

 makes at first sight on the Mineralogist — as " A light- reddish and fawn to peach 

 coloured matrix, which has sometimes a glimmering lustre like that of Lepidolite ; 

 hardness about 6.0 Mohs, but often hard enough to strike fire with steel, where it ap- 

 pears to pass into chert, which also appears in the vein stuff. The fracture is even- 

 ly granular, inclining to splintery, streak faint pink or reddish white, opaque." 



This specimen, sent to the Society, I should thus describe as to external appear- 

 ance. It is a massive matrix, mixed with bluish and greenish white chert, with nests 

 and brief veins and specks of galena, so interspersed through it that it is impossi- 

 ble to procure any notable quantity free from some intermixture without perhaps 

 destroying the specimen. Its colour varies from a light tile red, through light-orange 

 and pink-red, to a whitish-red orange; the weathered surface would be, judging 

 from the little we possess, dark-red brown, with perhaps reddish-white veins, but 

 always dull. 



The fracture is granular and somewhat splintery, glittering in some places, and 

 is thus like a fine-grained red sandstone ; here and there are nests of an orange 

 brown colour with some appearance of crystallisation, like the fine varieties of car- 

 bonate of iron, which they may possibly be. I could not so much disfigure our single 

 specimen as to pick out enough for examination. 



The fracture is evenly granular and perhaps may incline to splintery, as Captain 

 Newbold observes ; but there is no fair opportunity of judging of fracture in chip- 

 ping off minute bits for analysis.
