384 Proceedings of the Asiatic Society. [March, 



We have received from our able contributor Lieut. Sherwill, of the 

 Shahabad Revenue Survey, his splendid map of that district, which fully 

 equals the former one, and he has added to it also some notes which, 

 together witli his magnificent collection of specimens (noticed in report 

 of November 1845, when the present map and notes were promised), are 

 like the former on Zillah Behar, unequalled by any contribution yet sent 

 to the Society, as the fruit of the labours of a public officer in a most 

 active department, yet finding time to combine with them, and to add 

 so highly to their value, such researches. In reference to these maps I 

 have to submit for the orders of the Secretary and the Society the fol- 

 lowing letters. 



No. 61. 

 To H. Piddington, Esq. 

 Sir, — As I am desirous of having the Geological maps of Zillah Behar, and the 

 southern portion of Zillah Shahabad lithographed in the Government Press, and 

 as the original of these records are in your possession, I shall feel obliged by your 

 making them over to me, at your earliest convenience, for the purpose specified 

 above. 



2nd. One lithographic impression of each map will be duly made over to you 

 when received from the press. 



I have the honour to be, Sir, 



Your most obedient Servant, 



H. L. Thujllier, 

 Offg. Deputy Surveyor General. 

 Supt. of Revenue Survey's Office, 

 Calcutta, the 6th March, 1847. 



Capt. H. L. Thuillier, Offg. Deputy Surveyor General. 

 Sir, — In reply to your letter of this date, 6th, I beg to say that the maps in ques- 

 tion are presented to the Asiatic Society for the Museum of Economic Geology. 



2. Major "Wroughton took a copy of the Geological map of Zillah Behar, which 

 is no doubt in your office. 



3. That of Zillah Shahabad will be submitted to the Society at its meeting on 

 the 10th, when I will not fail to take the orders of the Secretary and the Society 

 concerning it. There can be no objection, but on the contrary great advantage in 

 having these valuable labours of Captain Sherwill's made as public as possible, but 

 the originals I apprehend must eventually remain with us. 



I have the honour to be, Sir, 



Your obedient Servant, 

 (Signed) H. Piddington,
