contains in many places dendritical delineations of manganese, and occasionally a small quantity of spathose iron.

§ 56. In the road which leads from the Wych to Colwall-green, and immediately at the foot of the range, the argillaceous rock occurs in strata bearing N. and S. but dipping cart at an angle of 60°. It is mixed with calcareous particles, includes, as usual, balls of limestone, and abounds very much in petrifaction's. I obtained specimens of the following varieties.[1]

a. A small madreporite, the stars of which are bounded by circles. In the cells of this there is a small quantity of red sulphate of barytes.

b. Different species of the porpital madreporite.

c. A turbinated madreporite, with a longitudinal section of a ramose madreporite.

d. A ramose madreporite, with terebratulites.

c. A coralloid, neither the form or structure of which can be defined.

I am informed that the chain coral is also to be met with in this place, but I did not find any specimen of it.

§ 57. About two hundred yards beyond this argillaceous rock, the limestone appears dipping towards the west, but as there is very little of it exposed, I could not make any exact observations as to its position. A short way to the westward is Stony-way quarry, where the limestone strata are seen in a very different position from what I found them in any other part; for in place of their direction being parallel to that of the range, as is generally the case with all the stratified rocks, particularly towards the north, it is at right angles to it: their bearing is E. and W. and they dip N. 35°.

§ 58. Near Eventon, there are very large quarries of limestone,
