Mr. Henwak exhibited some very beautiful specimens of arsenite 
of copper, acicular or tiled copper, and velvet arsenite of copper, col- 
lected by his grandfather from Cornish mines, 
Mr. Wonror exhibited a specimen of Deilephila Livornica, striped 
hawk moth, caught at Brighton this year by Mr. Gates, and varieties 
of the poplar hawk moth. Also three birds, lent by Messrs. Pratt and 
Sons : the Iceland Gull, a very rare bird in Sussex, shot recently, off 
Brighton, by Mr. Goldsmid, of Brunswick Square ; the shore lark, an 
occasional visitor ; and the grey phalarope, which had been somewhat 
abundant in the south this year. 
Mr. SeweE tt exhibited a bone, obtained at a depth of 14ft. in Nor- 
folk-square, which resembled a human tibia more than the bone of any 
of the animals,—such as the horse, ox, elephant, or deer,—associated 
with the Post Pliocene. 
Mr. C. Smita exhibited, and presented for the Society’s Her- 
barium, two mosses new to Britain, recently discovered by Mr. Mitten 
in Sussex, viz. : Pottia Littoralis, found near Aldrington, and Pottia 
asperulosa, found near Hastings. They had not yet been described, but 
would be in the Jauuary number of the Botanical Journal ; nor had 
they been seen by the botanical world at present. He had been 
fortunate enough to find one of them since Mr. Mitten’s discovery of 
them.
