conglomeratic grit of the Lamcta formation with tlie matrix of the peb- 
bles and sand grains replaced by manganese-ore, mainly psilomelane. 
In some places the itianganese-ore had assumed curious concretionary 
forms. A sample of conglomeratic grit and sandstone, with the man- 
ganiferous cement, and weighing about .10 lbs., was analysed by me with 
the following result —

The ore is evidently of no value. After eliminating the siliceous residue 
from the analysis, the remainder corresponds in composition with psilo- 
melane (16-459, 16-460, 16-464, and 16-465). 
6. Khepia Kund. 
To the north of Kheria Kund in the large tributary joining the right 
bank of the Ghorapachar river about 4i miles north of Katotia Mr. Vre- 
denburg collected some specimens of mixed wad and yellow ochre, some- 
times very calcareous. The localities are on the slate division of the 
Bijawars (16-4,38 and 16-461). 
7. Pan Kuan 
This is the name of a camping place situated about 6 miles alone the 
road from Kotkhera to Palasi along the northern edge of the Dhar For- 
est. It is marked on the 1-inch map as ' wklt.', and is about 6 miles east 
of Kotkhera. About | mile down the nala running south from the well 
a tributary joins the right bank. About 200 yards up this tributary 
there is an exposure of Biiawar limestone, the steeply sloping surface of
