[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 them 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 the[Pranheetah, 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 2\h. 16m. (or \ past 9 A. M.), while the lowest minimum 

 is seen at about 4 p. m, : with a second rise and. fall during the
