No. 63. 

 From Lieut. H. L. Thuillier, Offy. Deputy Surveyor General, 

 To H. Piddington, Esq. Curator Museum Economic Geoloyy. 

 Sir, — I have the honour to acknowledge the receipt of your letter, dated 8th 

 inst. and with reference to the 2nd Paragraph, beg to state, that a Copy of the Geo- 

 logical Map of Zillah Behar is in my office, but, as it is necessary whenever any 

 map is to be lithographed, to take the exact impression from the oriyinal if possible, 

 I trust the Society will not object to my being supplied with both the maps, execut- 

 ed by Captain Sherwill, for the purpose above specified. 



2. On the Maps being lithographed, the Originals shall be returned, together 

 with one Colored Impression of each of the Districts. 



I have the honour to be, Sir, 



Your most obedient Servant, 



H. L. Thuillier, 

 Supt. Revenue Survey's Office, Qffff. Deputy Surveyor General 



Calcutta, 9th March, 1847. 



I have put into the form of a paper for the Journal the examination 

 of a new Carbonaceous Mineral, which I have named Tremenkeerite. 

 It is a variety of the Anthracinse, but neither Anthracite nor Plumbago, 

 and is thus well entitled to a separate name. 



(Signed) H. Piddington, 



Cur. Mus. Eco. Geoloyy. 



Report of the Curator, Museum of Zoology. 



My Report for this evening's meeting is more brief than usual ; and 



so much time has been expended during the past month in setting up the 



skin of the Giraffe, that I have but a small collection of other mounted 



specimens to exhibit. The donations for the museum are as follow : — 



1. G. H. Bushby, Esq., Secretary to Government. A living specimen of a 

 Marmot (Arctomys bobac, Pallas, v. tibetanus, Hodgson), from Sikim. This little 

 animal is not more than a third grown, is quite tame, and seems likely to bear the 

 difference of climate, as it does not appear to be incommoded by the heat. 



2. G. T. Lushington, Esq., of Almorah. Two skins of the Tibetan Fox (Vulpes 

 nipalensis, as erroneously designated by Mr. Gray). 



3. D. C. Money, Esq. A specimen of a Nilotic Crocodile (Crocodilus vulgaris), 

 taken near Thebes, and quite distinct from Cr . palustris , Lesson, of the Ganges, &c. , 

 which is regarded as a mere variety of the same by MM. Dumeril and Bibron. The 

 length of this specimen is 10 feet ; and we have stuffed examples of Cr. palustris 

 and Cr. biporcatus, of the same length, from the neighbourhood of Calcutta. 



Also a mummied Ibis, the skeleton of which will perhaps bear setting up. 



4. R. Templeton, Esq., M. D., of Colombo. A further collection of Cinghalcsc
