ticularly indebted to Mr. G. J. Symons for much valuable information 
on this subject. 
Mr. Sewe 1 then exhibited a series of fossils, very kindly sent 
down for exhibition from Mr. Charlesworth, and forming part of the 
Whincopp collection. Among the most striking were teeth of different 
genera of sharks, scales of fish and reptiles, coprolites, ear bones of 
porpoise, dental palates, tusk of walrus, and an illustration of a novel 
method of mounting small Natural History objects. 
The receipt was announced for the Society’s herbarium, from Mr. 
G. Davies, of a lichen new to Sussex, Bacidia muscorum, obtained that 
month at Patcham by Mr. Davies ; and a moss, new to Sussex, Fissidens 
decipiens, from the moist part of the Downs above Slindon. This moss 
“was common in wet rocks in mountainous limestone districts, as 
Cumberland, Lancashire, Wales, Cornwall, &c. It had hitherto 
escaped detection in Sussex, being confused with F. adiantoides. F. 
decipiens had pale-margined, densely areolated leaves, widely differing 
from the lax large round cells of the leaves of F. adiantoides. This 
moss also was found that month by Mr. Davies.

MICROSCOPICAL MEETING.—A 
GENERAL EVENING. 
Mr. Hennas, remarking on the minutes of the last meeting, said 
he wished to qualify what he had stated about the potash mode of ob- 
taining palates, which was admirable, when comparison or identification 
was the object, but for palates which had to be mounted, no plan was 
better than dissection. In killing for dissection, the creatures should 
be placed in cold water, and, when they extended their heads, hot 
water should be added. 
Mr. Wonror announced that their friend, Mr. T. Curties, had 
very kindly sent down for examination a box of slides, including some
