J 843.] Asiatic Society. 623* 



F. — Indurated and laminated shale, sometimes approaching to sandstone, ejected 

 from the crater, sp. gr. 2.5. 



G. — Red shale indurated to a sandstone, (probably from the heat underpressure,) 

 ejected from the crater, sp. gr. 2.6. 



A single specimen in the cabinet of the Asiatic Society is red at one end, grey at 

 the other, evidently shewing that they are derived from each other. 



H. — Burnt sticks picked up shortly after the eruption about the crater. 



Besides keeping our own cabinet well supplied, 1 proposed, with the approbation of 

 the Society, forwarding these as occasion may offer as follows : — 



1. Hon'ble the Court of Directors. 6. University of Christiana. 



2. Geological Society. 7. Geological Society of Pennsylvania. 



3. Societe Geologique de Paris. 8. Academy of Natural Sciences of 



4. Royal Cornish Association. Philadelphia. 



5. Sir H. T. De la Beche. 



Museum of Economic Geology. — We have received from Lieut. Phayre, Sando- 

 way, a set of clays from that place, six in number, and specimen of the best Tobacco 

 soil, as also a porcelain clay from Bassein. His letter is as follows : — 



Sandoway, May 5, 1843. 



My dear Sir, — I have the pleasure to send you a box, containing specimens of 

 the clays and earths of this district. All the brick clays are from the immediate vici- 

 nity of this town. I send also a specimen of Tobacco soil from the best Tobacco dis- 

 trict here. I am aware that you have formerly analysed Sandoway Tobacco soils, but 

 do not know whether those were procured, as this is, from the most famous Tobacco 

 land or not. There is no pottery of any kind made here, I am sorry to say. 



The white clay is said to be that from which the well-known Pegu pottery is made ; 

 it was brought from Bassein. Will you have the goodness to apply on board the 

 H. C. S. Amherst for the box to your address. A. P. Phayre. 



We have also received from Lieut. H. C. Mayne, Adjutant 4th Nizam's Horse, 

 specimens of the salt of the Loonar Lake, with the following letter: — 



Mominabad, May 26, 1843. 



My dear Sir, — In reply to your letter of March 22nd, I beg leave to forward for 

 the Museum Economic Geology of India, a specimen of the salt of the Loonar Lake. 



You will perceive that the specimen is composed of three distinct species of salt. 

 Large incrustations of this are left all round the edges of the lake, caused by the quick 

 evaporation of the water by the sun, and partly from the foam of the wavelets as they 

 beat on the shore. 



The situation of the Lake of Loonar, is about midway in a direct line from Jaulnah 

 to Hingolee, longitude about 76° 45', latitude about 20° P. Hoping that this may 

 prove an addition (however small) to the Museum, I shall use my endeavours to 

 procure for its use, any interesting and curious specimen that may come within my 

 reach, but not being a scientific character, I may be excused if I ever forward speci- 

 mens, &c. which the Museum may already possess, or of so common a description, as 

 not to be worth having. H. C. Mayne, 



Lieutenant, Adjutant 4th Nizam's Horse. 



P.S.— I have dispatched the piece of salt by this day's banghy to your address."
