PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. [June 19, 



LX. Diorite from Swinyard Hill, containing hornblende, white 

 felspar, and silvery mica. The more micaceous and felspathic por- 

 tion of the rock was analyzed. G=2'933 — 3-076. 



LXI. Diorite, Key's End Hill, containing greenish hornblende, 

 red felspar, and a little silvery mica. 



IX. Intrusive Traps. 



The trap-dyke^ have been fully described in Dr. Holl's paper, and 

 their position has been most accurately marked on the map which 

 accompanies it. The following Table shows their chemical compo- 

 sition, together with that of some other rocks, XCY.-XCVIL, which 

 may probably be regarded as contemporaneous with them, from Wales 

 and from the Charnwood-Forest district, and the more recent traps 

 forming small dykes erupted, after the deposition of the Old Eed 

 Sandstone, at Brock Hill and Bartestree, XCIII., XCIY. The series 

 commences with those at the south end of the Malvern chain : —
