which appears to be hornblende in a pecuHar state, probably ia 

 vi^hat of decomposition. 



Mica in veins and beds, enclosed in felspar, &c. 



Talc, enclosed in felspar, &c. 



Epidotey both compact and crystallized in veins, and occa- 

 •ionally forming an integrant part of the rock. 



Quartz, in veins, and imbedded in felspar. 



Heavy spar, in veins, 8cc. 



Magnetic iron ore. 



The rocks of this range are for the most part, where they can 

 be" seen above the surmce, ^^ confusedly heaped together;" so 

 that, except in two places, which will presently be noticed more 

 particularly, no decisive appearances of stratification are to be 

 observed, unless indeed we may be allowed to infer the exist- 

 ence of stratification wheresoever the hornblende rock assumes 

 a slaty structure, indicating the direction of the dip ; if this 

 inference be allowable, it may be assumed that stratification is 

 more common to these rocks than it appears at first sight. 



The nearest place to Great Malvern at which a strong ten- 

 dency to regular stratification appears, is about three miles on 

 the south of it, and about 100 yards beyond the stone which is 

 inscribed " Ledbury, four miles." The beds here consist chiefly 

 of red felspar, from an inch or less to a foot in thickness, 

 enclosing quartz and hornblende, rarely mica : the interstratified 

 substances are, hornblende, occasionally mixed with talc, and 

 sometimes including a thin layer of red felspar and quartz, or of 

 granular felspar with hornblende greatly resembhng mica, of which 

 the slaty structure is parallel with the beds of felspar : here and 

 there are layers of granular quartz, mica, felspar, and hornblende, 

 the plates of the mica being parallel with the general dip of the 

 beds ; hornblende, sometiaies of a slaty structure, occasionally 

 occurs in the same direction, but it now and then appears to 

 pass into ati earthy substance having somewhat the appearance 

 of lithomarge. These beds vary from half an inch to a foot in 

 thickness, and though not stratified with perfect regularity, are 

 visible for nearly 100 feet in length, and 12 or 14 feet in height, 

 «ikbove which the hill is covered with verdure. Many of the 

 ^beds may be traced for several feet. These beds dip at an angle of 

 «bout 20 degrees to the north-east. 



In this place, these beds are traversed by a dyke of green- 

 stone, about two feet wide, except that it narrows a little about 

 !8 inches above the road, and dipping nearly north, at an angle 

 of about 70° with the horizon. The top of this dyke protrudes 

 "libove the beds it traverses, as is represented in the following 

 sketch, but it was not to be perceived that these beds were at 

 all disarranged by it, the portions of them next to it not being 

 turned either upwards or downwards ; nor did they seem to have 

 iBuffered any alteration of texture or appearance where the con- 

 ^tact was complete. The greenstone of the dyke is so remark-
