The Thermometer Curves, show the coldest time of the 24 

 hours to be a few minutes before sunrise, and the hottest time to 

 be lh. 10m. p. m. but varying in different months from Oh. 30m. 

 to 2h. June on the whole is the hottest month and January the 

 coldest. The range of Temperature is greater in the hot than in 

 the cold season, the least occurring in November. The mean 

 daily range amounts to 12°. 



Resolved that the thanks of the Meeting be voted to Major Ja- 

 cob, and that his paper be set aside for publication. 



Read letter from Secretary to Government, dated 23rd Dec. 1856 

 forwarding Dr. Walker's Report on Coal boring at Kotah, a village 

 about 10 or 12 miles from the junction of the Wurdah river with 

 the Godavery. 



In 1841 Dr. Walker submitted to the Asiatic Society of Bengal 

 an account of some minerals found in the bed of the Godavery, of 

 the nature of Slate Coal, with a few remarks on the Geological 

 features of the place at which they were discovered. The account 

 will be found published at page 341, vol. 10 of the Journal of the 

 Asiatic Society of Bengal. 



In consequence of the indications set forth in that paper a bor- 

 ing operation was determined on, and entrusted to Dr. Walker's 

 superintendence. 



The Rods, Drills, and Augers of the Boring-Machine were 

 made up atBolarum — about 30 feet was pierced on the first day ; 

 afterwards, falling in with Argillaceous Limestone it took 9 days 

 to get through a foot. At the depth of 29 feet a bed of Shale 

 and Slate Coal was met with. The whole depth pierced was only 

 34 feet 7 inches. 



Dr. Walker infers that a Coal field may be found at Kotah for 

 the following reasons. 



1st. The strata accompanying the slate- Coal are those which 

 are found along with deposits of this mineral in other parts of 

 the world. 



2d. The fossil plants apparent are identical with the fossil plants 

 of the true Coal measure.
