xxxiv Proceedings of the Asiatic Society. [April, 1844. 



When at the Museum a few days ago, I did not perceive amongst the natural curio- 

 sities any specimen of this enemy to the vegetable kingdom, and they may not there- 

 fore prove unworthy of reception.

Report of the Curator Museum of Economic Geology and Geological 

 and mlneraloglcal departments, for the month of march. 



Our zealous correspondent Captain Newbold, Assistant to the Commissioner, Kurnool, 

 Geological and Mineralo- has sent us from Beypoor, near Calicut, a specimen of the 

 gical. lignite of the beds of that locality which, he thus describes. 



"By to-day's banghy I have the pleasure to forward to the Society a specimen of 

 the lignite from a bed of considerable extent in the laterite sandstone near Beypoor, 

 in the vicinity of Calicut, on the Western Coast, discovered by myself in 1840. It is 

 associated with sulphur, sulphates of alumina, iron, retinasphalt and mineral coal. 

 The shales immediately in contact have a rarely perceptible dip, are black, car- 

 bonaceous and aluminous, and contain scattered spangles of mica. The bed of 

 lignite itself is from one to three feet thick, and can be traced about half a mile up 

 the river. General Cullen recently writes me, that he now sees much of this carbona- 

 ceous deposit in Travancore, and that it is very extensive. It exhibits itself in beds 

 of black clay and lignite of considerable thickness in the laterite cliffs along the W. 

 Coast from Quilon to Venkully. Deposits of the same kind occur about the same 

 level at the distance of two or three miles inland. " 



We have to acknowledge from Government, a further addition to our knowledge of 

 the Cheduba group in a report from Lieut. Hopkinson, Assistant Commissioner, 

 Arracan, who was also sent by the Commissioner, Capt. Bogle, to examine the spot 

 where the Volcanic Island had appeared, and who, though he unfortunately was not 

 acquainted with Mineralogy or Geology, has most zealously fulfilled his mission. His 

 report will be incorporated in mine, and I may remark here, that several of his speci- 

 mens are of very considerable interest.
