THE GEOLOGIST. 
November 20.— 1, "On the Borey Basin, Devonshire." By J. H. Key, 
Esq., communicated by Sir C. Lyell, F.G.S. 
The author first described the physical features of the Bovcy Basin, and then 
the strata, as proved by borings and diggings for clay and lignite. Having 
pointed out the evidences that exist of the basin having once been a lake in 
which the several strata of clay, sand, lignite, gravel, &c., were deposited, and 
having considered the probable conditions of such a lake having been gradually 
filled up by fluviatile deposits brought do^Ti from neighbouring granitic hills, 
the author remarked : — 1st. That the Bovey deposits are composed of materials 
almost identical with the component parts of granite. 2. The strata run, for 
the most part, parallel with the outline of the marginal hills, and dip from the 
sides towards the centre, often tliinnmg away in that direction. 3. The finer 
material is deposited towards the sides, and the coarser towards the centre. 
4. Where the basin is contracted the finer beds often disappear ; but thicken 
where the basin widens. 5. That the upper beds of the northern part are 
coarser than those of the middle and lower portions. 0. On the eastern side 
the fine clay beds are more developed than on the western side. 7. The 
various beds run in the direction of, and seem to point to, the River Bovey as 
the soui'ce from whence they were derived ; but the old outlet of the lake was 
towards Torbay, and not along the Teign as it is at present. Some observa- 
tions on the peculiar absence of animal remains in these deposits, often rich 
with vegetable remains, concluded the paper, which was illustrated by several 
original plans, sections, and sketches. 
2. " On two Volcanic Cones at the Base of Etna." By Signor G. G. Gera- 
mellaro. Communicated by Sir C. Lyelt, E.G.S. 
These two cones occur' at Paternd and Motta (Sta. Anastasia) ; and the 
existing remains of their craters and nuclei were described in detail. The 
author concludes that these two were contemporaneous doleritic volcanic 
cones, that were formed in the Post-pliocene period, previous to the depo- 
sition of calcareous tuff of the vicinity of Paternd : also that they were cones 
of eruption, and not of elevation; for the neighbouring strata are not dis- 
turbed : and thas they were independent eruptions, and not parasitical cones of 
Etna. 
3. On some Eossil Brachiopoda of the Carbiniferous Rocks of the Punjab 
and Kashmir, collected bv A. Fleming, M.D., &c., and W. Purdon, Esq., 
E,G.S." ByT. Davidson,^ Esq., E.R.S., E.G.S. 
Dr. Eleniing's geological researches on the Salt-range and elsewhere in the 
Punjab, in 184:2-52, are recorded in the Journal of the Society, for 1853, in the 
Journ. Bengal Asiat. Soc. 1163, and in his Report on the"^ Salt-range, 1854. 
The species of Carboniferous Brachiopoda collected by Dr. Fleming and de- 
scribed and figured by Mr. Davidson, are Terehratula (vel Waldheimia) 
Flemingii, Dav., T. prohlematicn, Dav., T. subvesicidaris, Dav., Eetzict radialis, 
var. gr audi cost a, Dav. Athyris Moi/ssii, L'Ev., A. (vel Merista) snbtilitai Hall,

Mr. Purdon's collection comprises, besides several of the foregoing — Tere- 
hratula Ilimalayensis, Dav., Spirifera MoosaJcaUensis, Dav., Sp. Martin, 
var., Camarophoria JPurdomi, Dav., Product us Ptirdonii, Dav. P. Hv.rnholdtii,

Geologists' Asscctation. — The first meeting of this Association for the 
winter session was held on Monday, November 4, at Cavendish Square, the 
Rev. Thomas Wiltshire, M.A., E.G.S., President, in the Chair, and was very 
numerously attended. Thii'teen new members were elected.
