localities of the coal alluded to in the foregoing paper, we subjoin a reference o 
different numbers of the Gleanings, which will supply the deficiency. 
1. A full account of the Burdwan coal field will be found in vol. i. p. 261. 
2. Tim Chinakuri stratum has been lately discovered by a gentleman in the Bun 
wan district, and it promises to be a valuable acquisition. 
3. The Palamu and Sohagpur coal district is described in vol. ii. pp* 217, 218, 
4. The Silhet coal is alluded toby Mr. Jones in vol. i. p.284. 
5. An account of the Hostmngabad or Towa Nala coal is inserted in the present 
number, along with a plan and section. 
6. The so called Baghelpur coal was discovered in 1829 by Captain Turner: n 
seam near Patsandali, to the west of Bajmahl, and in the same range of hills : tin 
is a good road from Colgong to Patsanduh during the hot weather, and during tl je 1,11 
a hill stream is navigable fora considerable part of the way. Patsandali is distant 
miles from Colgong, the nearest point on the Ganges.” The coal is loaded there 
4 annas per inaund ; but what has been hitherto extracted, has proved very bad- 
7. The Chanda coal is only known from specimens brought by natives, and a PP a 
rently picked up in the bed of a dry Nala. » . 
8. The Himalayan lignite is described by Captain Herbert in the first volume o 
the Transactions of the Physical Class of the Asiatic Society. | e 
9. Of the Manipur coal, we have Dr. Richardson’s notice in the proceedings o 
same Society, dated the 20th April 1831. Gl. vol. iii. p. 125.

Perhaps the most successful mode of eliciting information concerning

codiles of India, would be to lay before your readers an account or ‘ ^ 
which have already been described, and which are regarded as distinct^

cific distinctions; I therefore send you as correct an account as mj 
means of information have enabled me to draw up, and I trust it may

to direct their observations and inquiries into the proper channels.
