ON THE STATISTICS OF DUKHUN. 229 
at the elevation of 4000 feet, in the hill forts of Hurreechundur- 
ghur and Poorundhur, and in the bed of the Goreh River at 
1800 feet, near Serroor. The matrix resembles that of the 
other amygdaloids, but the mineral imbedded is a glossy 
felspar in tables resembling Cleavelandite, crossing each other 
at various angles, and so abundant as to occupy a moiety 
of the mass. I have only remarked it in the above localities, 
and it does not appear to have come under the notice of the 
gentlemen I have quoted elsewhere. 
Minerals,—Minerals are not uniformly dispersed in Dukhun. 
In one part quartz predominates, in another chalcedony ; and 
these are more or less associated with jaspars, agates, horn- 
stones, heliotrope, and semi-opal or cachalong. In other places, 
particular members of the zeolite family prevail, nearly to the 
exclusion of the siliceous class; and elsewhere there is a 
diminution of minerals amounting almost to privation. Ame- 
thyst quartz is rare in Dukhun; when met with it constitutes 
the crystal lining the interior of geodes of agate. I have not 
seen it in veins. 
Pseudomorphous quartz is common; the most frequent 
impression is that of rhomb spar. Lime occurs only in three 
crystalline forms; rhomb, dog-tooth, and the dodecahedron. 
The first is found on the surface, and imbedded in masses of 
quartz and compact mesotype; the two latter forms are asso- 
ciated with ichthyophthalmite in cavities in the amygdaloid 
strata. ‘That comparatively rare mineral ichthyophthalmite is 
very common at Poona. 
_ Natural Salts.—Only two kinds of natural salts came under 
my notice, namely muriate and carbonate of soda; both are 
not uncommon; the first near to Ahmednuggur, Koond, 
Mawleh, and other places ; the latter at Kalbar Lonee. Salt- 
petre is artificial in Dukhun. 
Ores.—No other ore than that of iron is found in Dukhun. 
It occurs as a nodular hematite, associated at the source of the 
Kistna with laterite. This ore produces the celebrated 
Wootz steel. 
Organic Remains.—I did not meet with organic remains of 
any kind whatever; and Captain Coulthard in Sagar, Major 
Franklin in Bundelkund, and Captain Dangerfield in Malwa, 
were equally unsuccessful; and Mr. Calder, in his General 
Observations on the Geology of India, says, ‘ But hitherto the 
most striking phenomenon in Indian geology is the almost total 
absence of organic remains in the stratified rocks and in the 
diluvial soil.” Very recently shells are understood to have been
