considers to have taken place since the deposition of the Carbon- 

 iferous strata. 



Another feature in the geology of Lundy is the occurrence of intru- 

 sive dykes of greenstone, which penetrate both the granite and slate. 



Mr. Hall gives also a list of the minerals found in the Island. In 

 the granite there occur Beryl, Felspar, Muor, Grarnet, Mica, Eock 

 Crystal, and Schorl, In the slates are found Blende, Towanite, 

 Magnetite, Quartz, and a Zeolite. H. B. W.
