Pakariga nald, between Lour and Mangowa, we first came to a thick 
slaty limestone, generally whitish, earthy, and marly, and varying 
to yellowish, greyish, and fine splintery. At Mangowa the dip was 
to the north, a red slaty marl. About this part of the country we begin 
to see a distant range of hills, bounding our prospect to the south and 
south-west,—the Kymur hills ; judging from the outline, they appear to 
be sandstone with a horizontal stratification, and look as if a third 
platform or table-land existed in that direction. Beyond Raypira 
low hill appeared to the south of the road, of a thick slaty limestone 
similar to that at Pakkartga: the dip very slight and irregular ; 
layers of a black kind of porphyry are interstratified with it. This 
black rock sometimes changes suddenly to white, and appears vitrified 
exactly like porcelain. At Rewah the limestone was extensively laid 
bare in the bed of the river, but it is here principally massive, passing 
from grevish to bluish black and black, and exactly resembling the 
mountain limestone of England. At Rampur, one march beyond 
Rewah, strata of red and variegated marl, most of them calcareous, 
were exposed in the bed of the rivulet for two or three miles to the 
south ;—dip slight to the north. Beyond Rampur the same bluish 
black limestone appeared as at Rewah. At Patrdhat a similar lime- 
stone was resting on the variegated marl slates, with a slight dip to 
the north. Near Lohdwel we passed over horizontal beds of a crumb- 
ling green and red marl for a considerable distance. At Nagowar a 
similar limestone appeared to that at Patrdhat, resting like it upon 
the marl slate. But it here appears to abound in what I believe to be 
coralline remains, I might rather say, to be entirely composed of 
them. I forbear describing them, as I have sent specimens with this 
paper, which can be examined by those who have means of reference 
at hand*. I was not fortunate enough to discover any of the stems of 
ferns and gryphite shells, described by Capt. Franxuin; nor in my 
whole journey over this limestone did I meet with any other kind of 
organic remains than the one I have just now spoken of, though I 
made diligent search for them during a whole fortnight. They must, 
therefore, be extremely rare, and in this respect the limestone differs 
widely from any of the English limestones above the new red sand- 
stone. From this place we passed alternately over strata of sandstone, 
red marl slate, and limestone, without being able to trace their con- 
nection with each other, until we came to Hattah. Here on the slope

* The specimens are deposited in the As. Soc. Museum: but their nature has 
not been ascertained. They are identical with what FRANKLIN named “ stems of 
ferns.’’ See As. Res. xviii. p. 29.—Eb.
