[With reference to the latter part of Dr. Falconer's Report the only specimens ap- 
proaching coal that accompanied Dr. Walker's letter were forwarded to Dr. 
Falconer, and he reported upon Ihcm as follows.] 
I have detected structure in the Chennore coal under the micros- 
cope, consisting of glandular dotted vascular tissue referable proba- 
bly to the natural family of Coniferae. 
Plants of this order are met with in the Lias and Oalite, as well 
as in the coal measures, and the Chennore specimens furnish no de- 
cisive information as to the formation in which they occur.

tricts of the Soubah of Hyderabad.] 
I have already sent a communication on the coal found in the 
bed of theTranheetah, close to its junction with the Godavery, and 
to this I refer. The subject of rendering the Godavery navigable 
has lately been discussed, and some interest has been excited in 
what would appear to be a measure very feasible and very advan- 
tageous. Should this scheme ever be carried out, the mineral, con- 
veniently situated as it is, might be turned to profit. 
The surface of the coal measure has as yet so to speak been 
merely scraped, but from the impressions of fossils found on the 
coal, chiefly Lepidodendrous plants, there can be no doubt of a true 
coal mine being there in existence. 
[Major Jacob, H. C. Astronomer, Madras, placed at the disposal of the Society 
some Barometer and Thermometer Curves, and supplied a brief notice in 
explanation of them. The Curves have been accurately lithographed by 
Dumphy, and will be found at the end of this number, but on a smaller scale 
than those sent by Major Jacob, to suit the size of the Journal.] 
Plates (1) to (8) at the end of this number give the indications of 
the Barometer and Thermometer for the years 1852 — 55 as noted at 
the H. C. Observatory, arranged in curves so as to exhibit the peri- 
odical changes. In the case of the Barometer the curves for every 
month show very conspicuously the course of the daily tides, there 
being two well marked maxima and minima : the principal maximum 
occurring at 21/i. 16m. (or J past 9 A. m.), while the lowest minimum 
is seen at about 4 p. m. : with a second rise and fall during the
