Chap. V.] crystalline eocks. 119 



A very interesting example of this last feature may be seen in one 

 Enclosed fragments in ^^ ^^^^ ^^^ost prominent granite ridges near Chinna 

 granite veins. Vmigarum, about 3 miles north by west of 



Samiaveram " Travellers' Bungalow/' Avhere a mass of well foliated gneiss 

 of irregular shape^ but several feet in length,, is visil)le^ imbedded in the 

 mass of the pink granite. Again, in the largo and extended outburst 

 of granite which has taken place north-east of Togamullay, (a gneiss boss 

 20 miles west-south-west of Trichinopolyj) immense masses of hornblen- 

 dic schist, 30 or 40 square yards in extent, appear to have been, as it 

 were, floated about, while their ragged edges are lengthened out until 

 felspar, quartz, mica, and hornblende have been twisted into a thin rope 

 of different coloured strands. In all cases the laminae of felspar appear to 

 have been lengthened out and twisted to a greater extent than those of 

 the other minerals.
