376 Reports and Proceedings— 
quartzite, tale- and chlorite-schists, eclogite, and quartz veins, 
striking generally N. 20° E., and having varying dips. The eclogite 
was described at length, and special attention was called to the 
flattening of the contained garnets, which were probably originally 
almandite ; other evidences of great crushing were also noted. 
In this section and on most of the schistose lands of Mysore a 
dull grey, nodular, and botryoidal calcareous deposit, known as 
“kunkur,” is found in nullahs, on hill-sides, and on the detritus of 
old gold washings, and it was suggested that the contained lime was 
derived in great measure from hornblende-schists. 
Many quartz outcrops, large at the surface but diminishing in 
thickness downwards, were met with at the east end of the section ; 
these veins have a strike about N. 15° EK. to N. 20° E., coincident 
with that of the schists. 
Extensive gold-washings have been carried on in the ravines 
and hill-sides, and the mode of occurrence and character of the gold 
were described. 
The author considered the schists, as well as the quartz veins, to 
belong to very old series of rocks, probably Archean. 
2. Seringapatam Section.—The second section was taken in a 
south-easterly direction from the 72nd milestone on the Seringapatam 
and Bangalore road to the N.W. side of the village of Arakere. 
Gneiss, hornblende, and mica-schists, ete., were here met with, 
striking about N. 20° E. with varying dips. These were traversed 
by auriferous quartz-veins which had been largely worked, and the 
author gave a description of the former methods of extracting the 
gold. 
At the 8.E. end of the section the schists were found to be much 
broken by porphyrite dykes of much more recent origin, most likely 
of Tertiary age. A small granite dyke intersected the Elliot Lode 
diagonally, and was considered to be of Upper Tertiary age. 
3. General Observations.—The author described the results of 
traverses of other districts; he pointed out the evidences of great 
pressure which had broken up the gneissic rocks and compressed the 
schists, and conjectured that this might have been produced by the 
gradual rise of the Eastern and Western Ghats, and finally called 
attention to the great denudation which the Mysore plateau had 
undergone. 
An Appendix by Prof. T. G. Bonney, D.Sec., LL.D., F.R.S., F.G.8., 
gave an account of the microscopic characters of the schists, the 
flattened garnets, the porphyrites, etc., and in this it was pointed out 
that one set of rocks belonged to an ancient series which, even if 
wholly or in part of igneous origin, assumed their present mineral 
structure and condition at an epoch remote from the present, whilst 
another set was certainly igneous and of more recent date. 
4. “On the Durham Salt-district.” By E. Wilson, Esq., F.G.S. 
In this paper the author described the new salt-field in the North 
of England, occupying the low-lying country bordering the estuary 
of the Tees, and situated partly in Yorkshire and partly in Durham. 
The history of the rise and progress of the salt-industry in South
