Anantagherry, 17 th August, 1819. — On the south side of the hill 

 of Anantagherry, a very thin vein or dyke of basalt is seen running in 

 an east or west direction through the concentric granite. At the bot- 

 tom of the hill it is first seen about a foot broad and continues about 

 100 feet upwards, gradually decreasing in breadth until only a line in 

 thickness, when it disappears. It runs in a zigzag manner and does 

 not project above the surface. In it are enclosed small pieces of gra- 

 nite, which is of the same nature as that of the hill. The granite con- 

 tains compact felspar of a green hue, and the basalt glittering crystals of 

 basaltic hornblende. This basalt is easily fusible before the blow-pipe. 



Hydershabeepett, 20th August, 1819. — In the bed and on the banks 

 of a river running near this place, the mixture of the granite and trap 

 is very remarkable. In some places it is enclosed in it in the same 

 mode as the micaceous granite of Solokoondah, in others running in 

 thin veins, and lastly mixed in streaks, as if it had been melted with it 

 and flowed down. 



Hydershabeepett, 23rd August, 1819. — On the top of the hill I saw 

 in many places the rounded masses of micaceous granite enclosed in 

 the rock, which itself contained large scales of mica and garnets and 

 was in beds, generally very large grained and decomposing very fast ; the 

 top is above 500 feet above the plain. 



Hydershabeepett, Saturday, 28th August, 1819. — The bed of the 

 river which flows near this village, presents a very remarkable mixture 

 of the granite and trap in veins, and in rounded masses. The former 

 appear to be of later formation, since a vein passes through one of 

 these rounded lumps. The same vein is also heaved out of its course 

 several inches by some convulsion. I was able easily to fuse a small 

 piece of it before the blow-pipe. It more nearly resembles the basalt 

 vein of Anantagherry, than the common greenstone vein which is also 

 not so easily fusible. 



Monday, 30th August, 1819. — I observed on the summit that same 

 mixture of the granite as before mentioned. At this village I observed 

 a small rock with concentric layers and the mixed granite. 



Sunday, 12th September, 1819. — The hill of Babecondah is a mass 

 of concentric granite about 500 feet above the plain and occupies the 

 centre of a range of broken hills of the same nature, running about 5° 

 to the west of north and extending three or four miles. The principal
