Swan, Esq. In a letter to Sir E. I. Murcliison, K.C.B., F.E.S., F.G.S., 
etc. 
The litJiological and stratigraphical characters of the rocks of the Bos- 
phorus having been noticed, the author gave a general description of the 
fossils occurring in them, — namely, Sjpirifer (broad-winged and small 
species), Orthis, and other Brachiopods ; HomaUmotus and other Trilo- 
bites ; together with Corals of the genus Favosites associated with tlie 
well-known Pleiirodictyum prohlematicum. Graptolites were stated to be 
entirely wanting, and Cephalopods to be very rare. Mr. Swan therefore 
inferred that these strata were of the age of tlie Lower Devonian rocks of 
the Ehine. 
December 16, 1863.— 1. " On the Pebble-bed of Budleigh Salterton." 
By W. Vicary, F.G.S. With notes on the Fossils by J. W. Salter, 
F.G.S. — The south coast of Devonshire, from Petit Tor, near Babbacombe 
Bay, to a little beyond Sidmouth, exhibits cliffs of New Red Sandstone ; 
one of the beds of which, near Budleigh Salterton, is composed of pebbles 
of all sizes and of a flattened oval form: this bed attains a maximum 
thickness of about 100 feet, and some of the pebbles composing it were 
found by Mr. Vicary to contain peculiar fossils. 
Mr. Vicary gave a description of the physical features of the area over 
which the pebble-bed extends, and entered into the stratigraphical details 
of this and the associated strata, referring to Mr. Salter's note for infor- 
mation upon the affinities of the fossils. In his note, Mr. Salter observed 
that, on comparing the fossils of the Budleigh Salterton pebbles with those 
from the Caen sandstone in the Society's Museum, he found that all the 
species contained in the latter collection were also represented in the 
former. The general aspect of the fossils was stated to be quite unlike 
that exhibited by English Lower Silurian collections, and Mr. Salter 
therefore suggested that the exact equivalent of the Caen sandstone does 
not exist in England. This difference in the two faunas appeared to him 
to favour the theory of the former existence of a barrier between the 
middle and northern European regions during the Silurian period. 
2. " Experimental Researches on the Granites of Ireland. — Part IV. 
On the Granites and Syenites of Donegal, with some remarks on those 
of Scotland and Sweden." By the llev. Samuel Haughton, F.K.S. — The 
author discussed in detail the mineralogical composition of each of the fif- 
teen Donegal granites, and described the method usually employed by 
him in solving lithologico-chemical problems, coining to the conclusion 
that nearly half of these granites are not composed ^together of the four 
minerals (quartz, orthoclase, oligoclase, and black mica) which are found 
in them in distinct crystals, and that the remaining varieties, even if they 
be composed of these minerals, must have a paste composed of the same 
minerals, but with a slightly different composition. Professor Haughton 
' then discussed the composition of the syenites of Donegal, and instituted 
, 1 a comparison between the granites of that district and those of Scotland 
. I and Sweden, remarking that those of the last-named region have the 
, 1 same stratified structure as the granites of Donegal. 
f j 3. " On the recent Earthquake at Manilla." By J. W. Farren, Esq. 
f j Communicated by the Foreign Oliice. — In two letters to Earl liussell, 
I j the author descrioed the damage done by this earthquake, observing that 
J j 289 persons were killed, and a large number more or less injured.

J Teeth and Bones of Reptiles in Central India." By the late Rev. S. 
j Hislop. Communicated by Professor T. Rupert Jones, F.G.S. — The re- 
I mains alluded to consist of (1) a series of reptilian bones, some bearing
