tioned in Dr. Heyne’s Tracts on India. The mine is quite abandoned 
at present, and the adjacent village of Gantlapalem an extensive ruin." 
Fair traces of copper are again seen in the rocks of the old lead 
a mines at Jungumrajpilly in the Nullamullays, 
some few miles north of the road from Nundi- 
allumpett to Budvail. These were only cupreous stains and apparent 
impressions of crystals of copper pyrites and faint traces of native copper. 
These occur in strings of white quartz, which are striking through 
beds of silicious limestone. The fissures of deposition run north-north- 
east, south-south-west, with a dip of 60° westward, while the strata 
are at 50° east by north. 
The best traces of copper ore in the area under description are 
not, however, in the NEWER METAMORPH 
In the CRYSTALLINES ? à ICS, but 
on east side of field. in the CRYSTALLINE or gneissic series, just out- 
side the eastern boundary. This locality is that which was worked 
many years ago under the auspices of the old firm of Messrs. Hart 
and Simpson of Nellore and J. Ouchterlony, Esq., of Ootacamund. 
Mr. Charles ZE. Oldham examined this region and thus writes of it :— 
« In the Nellore district, I have noticed copper ore as occurring in 
one locality only. Near the village of Gunnypenta, 
0 in the Nellore. 
PIN close to the northern edge of sheet 77, about 12 
district. 
. A. Oldham's notes. : 
*: miles north by west of Ingemoor (long. 79° 37’), 
copper ore was quarried to some small extent many years since. 
At the time of my visit (June 1863), the small pits from which the ore 
was dug were filled with water, which prevented me from seeing 
satisfactorily the mode of its occurrence; but, as far as I could 
ascertain from observation and inquiry, there seems to have been a 
narrow band or bands of the ore, the green carbonate, running 
through the  hornblende-schists which are the prevailing rock here. 
A considerable amount was extracted, and then, partly from the vein 
proving less productive, probably thinning out, and partly from the
