3 BLANFORD : GEOLOGY OF NAGPtJU. 



Geological Survey of India for 1868, p. 26. A more detailed account 

 of the rocks is given in the present paper. 



It should be premised that, with the exception of the sandstone area, 

 the country was not closely examined, as much important work 

 remained to be done in the working season. No attempt was made at 

 following out the intertrappean beds ia detail, nor of mapping the 

 various forms of metamorphic rocks.

describing the earlier notices of the Geology of

Nagpiir. The first was a paper by Voysey, " On 



the Geological and Mineralogical Structure of the Hills of Sitabaldi, 



N£gpur, and its immediate vicinity," published in the Asiatic Kesearches, 



vol. xviii, pt. 1, p. 193; and in Gleanings of Science, 1830, vol. ii, 



p. 27. In this the basaltic rocks of Sitabaldi are the principal subject 



treated of, and the sandstones are scarcely mentioned. 



The next contribution was by Captain F. Jenkins, As. Res., xviii, 



pt. 1, p. 195, in a paper entitled, "An account

of some minerals collected at Nagpiir and its 



vicinity," with remarks on the Geology, &c., of that part of the country. 



This account which appears to have been drawn up with Voysey's 



assistance contains many details of the rocks, and is accompanied by a 



very fair Geological map. Malcolmson's well

known article " On the lossils oi the eastern por- 

 tion of the Great Basaltic District of India, Trans. Geol. Soc, Lond., 

 Ser. ii, vol. v, p. 537, added nothing to Captain Jenkins's account of 

 the immediate neighbourhood of Nagpiir, but in a " Note on fossil plants 

 discovered in the sandstone rocks at Kamptee near Nagpiir," published in 

 the Journal of the Bombay Branch of the Royal Asiatic Society, vol. i, 

 p. 249, the same geologist first announced the discovery by Lieu- 

 tenant Munro of vegetable remains in the Kamthi sandstone. The 

 fossils figured are species of Glossopferis.
