The Thermometer Curves, show the coldest time of the 24 
hours to be a few minutes before sunrise, and the hottest time to 
be Ih. 10m. p. m. but varying in different months from Oh. 30m. 
to 2b. 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 at Bolarum — 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 plant;; 
of the true Coal measure.
