PLUTONIC ROCKS.—CABE I. 
Note.—It will be seen, from an examination of these specimens 
(Nos. 26 and 27, and No. 11), how widely individual. specimens from 
granitic dykes occurring in other rocks differ amongst themselves. All 
these specimens were taken from within a yard of one another: No. 11 
presenting a fine-grained appearance, with a vein of felspar; No. 26 
very much.coarser; and No. 27 showing an extremely coarse texture, 
with the plates of mica often forming small nests.
