hundreds of small brilliant crystals from Norway, from Spain, and 
from Bristol, did not find a single crystal in which the measurement 
of the angles precisely correspond with those determined by Haiiy, 
nor did he meet with a single example of perfect coincidence among 
the corresponding angles of any one crystal. The only measure- 
ments in which several specimens agreed were 94° 15’ and 85° 45’; 
and these, therefore, Mr. P. is inclined to consider as approaching 
nearer to the true dimensions of the primitive rhomboid than any 
other.. This want of coincidence in the measurements of crystals 
which were selected on account of tbeir brilliancy and seeming per- 
fection, induced Mr. Phillips to subject to similar examination some 
remarkably fine crystals of sulphate of barytes, and in these also a 
similar disagreement in the dimensions of the same angle in diffe+ 
rent crystals was found to occur, amounting to at least 26’. He 
then examined some good cleavages in the direction of the primitive 
planes, and found six of them agree perfectly in giving 101° 42’ 
for the obtuse angle, and 78° 18’ for the acute angle, of the primi- 
tive rhomb; a result differing materially from that of Hauy, who 
states them to be 101° $2’ 13” and 78° 27’ 47”. 
A communication from Dr. Berger, of Geneva, was read. In 
this paper Dr. B. describes the scapula of some unknown large 
animal which was recently found in the lake of Geneva. 
Nov. 3.—A paper from G. Cumberland, Esq. on certain organic 
remains found near Weston Super Mare was read. Closely adjacent 
to Weston Super Mare is a promontory, the summit of which is 
occupied by a Roman station called Whorlbury Camp; and at 
the northern extremity of this promontory is a small rocky island, 
resorted to by fishermen at low water. A narrow horse road leads 
from the downs above to this island; on the left hand ef which, 
opposite to the sea, may be observed a bed of soft red sand-storie 
interstratified with others of hard red marl. The entire thickness 
of these beds is about six feet, they dip at an angle of about 47°, 
and rest on a grey lime-stone destitute of shells. In the marly part 
of these beds occur numerous substances, resembling pieces of 
bamboo separated at the joints. ‘Their length rarely exceeds five 
inches, but their thickness varies from a quarter of an inch to five 
inches. Their substance appears to be red clay, more or less pene- 
trated by quartz. There is no apparent passage from one joint to 
the next, although the ends are often in contact ; from which cir- 
cumstance Mr. C. concludes them to be real vegetable remains. 
These same substances also oceur at Uphill, on the opposite point 
of Weston Bay, but are there imbedded in a coarse grey shell 
lime-stone. Just over the outburst of these beds at Whorlbuty 
Camp is a pale yellow sand-stone, containing long white stalks of 
Abayonia, which when in fragments might easily, from their cellular 
structure, be mistaken for fossil bones. 
‘In another letter, addressed to the Secretary, Mt. Cumberland 
mentions the discovery of a new and very elegant bottle encrinite 
in the black rock of Bristol.
