stating it to be of a formation posterior to the sandstone, and suggesting 

 that it is the deposit of a great lake which once filled the valley between 

 the Bundair and Punna hills. The paper closes with remarks on the 

 metamorphie rocks of Jubbulpur. 



In Lieutenant W. S. Sher willy's note on the geological features of 

 1846, Lieutenant W. Zillah Behar* are some allusions to the Vindhyan 

 s. SherwUl. sandstones, but the paper refers more particularly 



to the crystallme area to the eastward. 



The same author, in another paper, however, on Zillah Shahabad,t 

 1847 Lieutenant W. describes the physical featm-es of the Kymore 

 S. Sherwm. j^.|2g ^^^ table-land ; then the sandstone of which 



these are mainly formed, and the " mountain limestone'' (lower Vindhyan), 

 which he correctly believes everywhere to xmderlie the former. The 

 sacred caves of Gupta are referred to, and finally are enumerated the 

 economic products of these hills, in which are included chalk, iron ore, 

 indurated reddle, alum ore, martial pyrites, sulphate of iron, and potstofie. 

 Amongst the posthumous papers of Mr. Williams was a report on 

 1852 Mr. D. H. ^^^ examination of the Kymore moimtains, the 

 ^ ^^™^' chief object of which was to ascertain the cor- 



rectness or otherwise of the general opinion that the strata of this range 

 constituted a portion of the coal measures. Commencing in the neigh- 

 bourhood of Akbarpur, Mr. Williams found beneath the sandstone 

 which forms the mass of the hills there, a thin-bedded, bluish-grey, 

 argillaceous limestone, resembling lithologically the lias limestone of 

 Europe. Its thickness he estimated here at 700 feet, and no traces of 

 organic remains were apparent. Not far fii-om this a bed of coal was 

 reported to have been discovered, which Mr. Wilhams found to be nothing
