An extract read from a note by the Rev. S. B. Windsor, present- 
ing to the Museum an insect of the Mantis tribe, (in spirits), taken 
at Bishopsbourne. 
From the Rev. T. J. Ewing, of New Town, were received spe- 
cimens of Stalactite, from the extensive limestone caverns near 
Deloraine ; also fragments of shale, exhibiting very distinct im- 
pressions of fern leaves from the new coal shaft near Newlands. 
A large specimen of the coal (anthracite) from the same locality lay 
upon the table. 
Mr. H. Hull submitted specimens of iron pyrites crystallized in 
small cubes from the shale over the same coal. 
The Secretary exhibited specimens of a new combustible mineral 
lately received from Mr. Wheeler, of Port Sorell, and said to occur 
abundantly near the mouth of the Mersey River. It is of an ashy 
brown colour, slaty structure, and is tenacious and semi-flexible. 
It ignites readily when held toa candle, and burns with a bright 
white flame, yielding much smoke, and giving out a peculiar odour : 
its geological position and associations not ascertained.

sented to the Museum by James Barnard, Esq.

Cape Grim, and familiarly known on the northern side of the Colony 
as Turkey stone, were received from James Gibson, Esq., of Circular 
Head. 
A box of valuable mineral specimens from the collection of Lieut. 
Smith, R.N., recently gone to England, was received. 
The Rey. Dr. Lillie placed before the meeting a hand specimen of 
rock consisting on one side of basalt, and on the other of limestone 
altered and rendered semi-crystalline by the contact; also the cast 
(a fragment only) of a fossil (not named) from the limestone near 
Tolosa. 
Mr. Propsting presented a skin of the Gang Gang Cockatoo 
(Callocephalon Galeatum) of the southern shores of Australia, and 
an occasional visitant on the northern coast of Van Diemen’s Land; 
also a skin of Gdienemus Grallarius, or Southern Stone Plover. 
A short paper read by Mr, H. Hull upon the gigantic Gum Tree
