cases, where the softer coal of the plants has been pressed down 
upon the harder coal of a layer of the pebbles, by the cleavage of 
the former, however distorted the plant may be, presenting an uni- 
form parallelism, while the cleavage of the coal forming the pebbles 
is parallel with the sides of the pebbles, which are inclined in all 
possible directions. 
The pebbles consist principally of the common bituminous coal of 
the neighbourhood, but two have been found composed of cannel 
coal, the only seams of which, existing in the lower measures, occur 
about 2000 feet below the conglomerate bed. 
The Cilfay sandstones and the measures at Penclawdd, in which 
the first-mentioned pebble was found, form part of the Pennant grit ; 
and there is reason to believe, that throughout the whole of this 
great mass of sandstone, about 3000 feet thick, occasional beds of 
coal pebbles are to be met with: but Mr. Logan has not seen any 
associated with the lower measures. 
March 11.—Rev. Richard Taylor, M.A. of the Bay of Islands, 
New Zealand; Graham Francis Moore, Esq. Brick Court, Temple ; 
and Samuel Smith, Esq. of Combe Hurst, Kingston, Surrey, were 
elected Fellows of this Society. 
A paper was first read, ‘On the Rocks which form the West shore 
of the Bay of Loch Ryan in Wigtonshire, N. B.” by John Carrick 
Moore, Esq. F.G.S. 
The peninsula of the Ryans extends about thirty miles from N. 
to S., and is about seven miles across at its greatest breadth, or from 
Stranraer to Port Patrick. In the geological maps of M. Necker, 
Dr. Macculloch, and Mr. John Phillips, it is coloured as part of the 
great graywacke chain, stretching from the Irish sea to St. Abb’s 
Head, and the chief part of the rocks composing the peninsula, Mr. 
Moore says, undoubtedly belongs to that epoch; but he has ascer- 
tained from an examination of the district during the summer of 
1839, that others of a more recent date also exist. 
The portion of the peninsula particularly described by the author, 
extends about eleven miles from north to south, and about five from 
east to west; and is bounded on the W. and N. by the Irish sea, and 
on the E. by the Bay of Loch Ryan. The formations of which it 
consists are—l. Graywacke, 2. Trap rocks, 3. Coal measures, and, 
4. a red breccia. 
1. The graywacke constitutes the greater part of the district, the 
beds being nearly vertical and the prevailing strike E. by N. At 
the northern extremity, near the Corsewall Lighthouse, are beds 
of conglomerate composed of rounded masses of granite, with peb- 
bles of serpentine and other rocks. In the little bay of Sloughna- 
garry, at the most southern point, where the graywacke shows itself, 
Mr. Moore found in a slaty rock alternating with compact beds, an 
abundance of fossils, determined by Mr. Lyell to be graptolites. 
2. The trap rocks occur at two points, one near the northern ex- 
tremity of the peninsula, on the farm of Balscallock, constituting a
