478 Geological Remarks between [Sepr, 
to the east of the village were horizontal strata of sandstone exposed 
to view ; at the first nala, lower down, was a whitish argillaceous 
limestone overlaid by sandstone; at a nala still lower down, layers 
of sandstone, limestone, and red mar] slate were to be seen interstratified. 
A few miles further on, at Nagar, a low cliff on the side of the river 
Sonar shewed a section of the strata as follows: uppermost layers, 
sandstone ;—middle, red marl slate ;—lowest (in bed of the river) argil- 
laceous limestone. I had before conjectured that this would be the case 
from the continual alternations of sandstone and limestone, every mile 
or two along the road by which we had travelled, though both were 
horizontally stratified, and little or no difference of level was to be 
noticed. This led me to conclude that the limestone was of no great 
thickness, nothing more indeed than a bed in the sandstone, and the 
appearances I have now described at Hattah and Nagar confirm this. 
Capt. FRANKLIN speaks of the limestone being not more than 100 feet 
thick upon the sandstone, I have never found it 10 feet thick, without 
layers of sandstone interstratified. Beds of limestone of a similar 
kind do not appear to be uncommon in this formation: near Cheyn- 
pir, about 35 miles to the south of Ghdztpir, I had an oppor- 
tunity of examining one of these. The sandstone range there presents 
nearly the same appearance as at the back of Mirzapar, except that 
it is somewhat higher, and the dip, as far as I traced it, (which was 
about 20 miles to the eastward) is inwards, or to the south and south- 
west. Ata place called Mussaye the limestone may be seen cropping 
out at the base of a sandstone hill, and dipping at a considerable angle 
to the south. It is usually slaty, but varies much in character in 
other respects, passing from grey to black, and then resembling the 
English mountain limestone. No remains could be found in it, but 
about 10 miles to the eastward it is seen again at Bétraband. But I 
have neither seen, here nor elsewhere, any of the beds of loose slate 
and clay that accompany the lias in England. Were it necessary to 
class these with any of the European formations, transition limestone 
would be the most proper name for them. Though it is certainly more 
correct to consider them merely as beds in the sandstone; which sand- 
stone, it must be remembered, is never found reposing on any but 
primitive rock. 
As we leave Patteria, the easternmost extremity of the hills of trap 
fronts us, and the road winds along it for some distance. For 30 or 
40 miles to the east of this the strata of sandstone had become broken 
and disturbed, dipping in various directions. Rolled pebbles of sand- 
stone and pieces of agate and chalcedony are seen lying about, not
