Vou. TI. Parril.  1841—1842. No. 82. 
Nov. 3.—Joseph Martin, Esq., of Swansea, was elected a Fellow. 
A memoir, entitled “ Supplement to a ‘ Synopsis of the English 
Series of Stratified Rocks inferior to the Old Red Sandstone,’ with 
Additional Remarks on the Relations of the Carboniferous Series and 
Old Red Sandstone of the British Isles,’” by the Rev. Adam Sedg- 
wick, F.G.S.,Woodwardian Professor in the University of Cambridge, 
was begun. 
Nov. 17.—Charles Nicholson, M.D., of Sydney, New South Wales, 
was elected a Fellow. 
Professor Sedgwick’s paper, commenced at the preceding meeting 
was concluded. 
The author states that his former synopsis* is now modified ; Ist, 
by the new classification of the stratified rocks of Devon and Corn- 
wall (Devonian system) ; 2ndly, by a larger knowledge of fossils de- 
rived from some of the groups described ; 3rdly, by new observations 
made during the past summer in the south of: Ireland, the south- 
western parts of Scotland, and in the north of England. 
New Rep Sanpstone.—1. Hxgland.—It is shown, by sections de- 
rived from Warwickshire, that the upper part of the new red sandstone 
is sometimes unconformable to the lower part, which represents the 
magnesian limestone and lowest division of the new red sandstene 
sroup. Itis also shown that the coal-measures pass into the overlying 
new red sandstone series through the intervention of bands of red marl 
alternating with two bands Of". freshwater limestone, the whole beds 
of passage being loaded with common coal-plants. The author then 
discusses the sections near Whitehaven. They show no passage 
from the lower new red sandstone (rotheliegende) to the coal-mea- 
sures; but they show that the flora of the cval-field existed appa- 
rently in full perfection during the period of the lower new red sand- 
stone: of this flora he has obtained many new specimens. He states 
that the additional facts lend support to the suggestion thrown out 
by Mr. Murchison and himself respecting the age of the coal-field 
on the flanks of the Hartz. 
2. Scotland.—The new red sandstone of Dumfries-shire is continu- 
ous with that of the plains of Carlisle, and is seen overlying the coal- 
measures from the valley of the Esk, near Canobie, to the neighbour- -
