Of the last two these are the first interiors found, and have been 
identified by Mr. Thomas Davidson, F.R.S., F.G.S. Mr. Hunter 
also exhibited fine remains of Gyrolepis Rankint from shale below 
the ‘Main Post Limestone,’ and from the ‘ Rae’s Gill beds.’ Besides 
the above, there were exhibited several polished sections of Litho- 
strotion, Alveolites, &c.; also several specimens of Serpulites car- 
bonarius, Spirorbis globosus, Entomoconchus Scouleri, and the Trilo- 
bite Griffithides mesotuberculatus of slightly varied forms, all from 
the prolific ‘ Main Post Limestone.’ The only Fish-remains found in 
this limestone are fragments of Petalodus Hastingsie, Rhizodus 
EMibberti, Cochliodus magnus, another species of Cochliodus, and a 
Pecilodus. Only one specimen of Productus giganteus was found in 
the ‘Main Post Limestone,’ showing that the species was dying out, 
while only 23 fathoms lower down it is found in great abundance. 
Above Rae’s Gill ironstone, coprolites are found which have yielded 
many minute bivalved Crustacea, one coprolite alone having yielded 
300 specimens of a new species named by Prof. Jones and Mr. Kirkby 
Cypridina Rankineana, after Dr. Rankine of Carluke, who has 
already added many new forms to the list of species from this 
locality. 
GEOLOGICAL Society or GLiascow.—I. March 30; E. H. 
Wiinsch, Esq., Vice-president, in the chair.—1l, ALEXANDER Bryson, 
Esq., F.R.S.E., read a paper On the Insufficiency of the Evidence 
adduced by Sir Charles Lyell* to prove the Upheaval of the Shores 
of the Forth since the Roman Period. Ue said, that all the geolo- 
gists who had written on the subject appeared to have gone into its 
investigation to support the views of Maclaren, who, though un- 
equalled in Scotland as a topographical observer, had made a series 
of mistakes, only from his non-acquaintance with general natural 
history—the habits of marine life in particular. Chambers and 
Geikie had also formed erroneous conclusions from a like want of 
preparatory study; and Sir C. Lyell had become the advocate of a 
theory, suggested by partial and in some cases hurried examination 
of phenomena, which a careful verification might have convinced 
him were not only utterly inadequate to sustain it, but were in many 
instances quite adverse to it. Mr. Bryson referred at considerable 
length to the various phenomena adduced by Sir C. Lyell and the 
gentlemen he had quoted, in support of their views, and stated the 
results of repeated investigations of them by himself and Dr. Bain, 
which proved that these were not caused by any upheaval of the 
shores of the Forth, but solely by the deposition of detritus from the 
various rivers flowing into the Firth, aided by the action of tides and 
storms. The large deposit of Oyster-shells near Inveravon, 60 feet 
above the present high-tide level, he attributed to a very high tide 
and storm-waves in the year 1766, referred to by Boece in his ‘ Ms- 
toria Scotorum, which had caused a great inundation, destroyed 
many villages, laid waste the district, and occasioned a great loss of
