Mr. Horner on the Mineralogy of the Malvern Hills, 309 



contains in many places dendritlcal 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 east at an angle of 

 60°. It is mixed with calcareous particles, includes, as usual, balls 

 of limestone, and abounds very much in petrifactions. I obtained 

 specimens of the following varieties.* 



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. 



e. 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, 



* I am indebted to Mr, Parkinson for this description of the organic remains.
