102 NERBUDDA DISTRICT. 



Malcolm's "Memoirs of Central India," published in 1823.* This 

 paper, full of accurate statements, evidently the result of careful obser- 

 vation, confines itself to descriptions of the lithology and mineralogy of 

 the district. 



Many of the rocks are well described, and the localities where they 

 occur, mentioned; and a Map accompanies the work, showing the general 

 boundaries of the area occupied by each. The date of the paper (1823J 

 will, to a Geologist who remembers the state of the science at the time, 

 sufficiently explain why Captain Dangerfield's results were not based 

 upon any geological classification now recognised ; nor would Captain 

 Dangerfield's paper convey to the mind of the geological reader of the 

 present day any very definite ideas of the structure of the country he 

 examined, and which he described from the point of view of a disciple 

 of Werner. 



A few years later (1828) Captain Franklin contributed to the Asiatic 



Society of Bengal, and also to the Geological 

 1828. Franklin. . 



Society of London, a valuable memoir on the 



Geology of Bundelcund. In this he chiefly enters into the discussion 



of the Geological relations of the rock masses ; he identifies the sandstones 



of the Table-land with the central portion of the New Red System of 



England, principally it would seem, on the strength of some saliferous 



deposits which were stated to belong to the group. He describes also 



the limestone of the Rewah plateau, and alludes to fossil ferns, silicified 



wood, and a gryphsea, from its beds. His collections have, unfortunately, 



been lost, and no one, since that time, has been able to find any organic 



remains whatever in these rocks. Captain Franklin also described the 



crystalline rocks of the Nerbudda valley, and discussed their relations to 



the granite, stating further, that the latter, sometimes although not 



always, underlies the sandstones of the plateau, without the intervention 



between the two, of any of the bedded crystalline series. He notices two
