Proceedings. 165 
From Mr. Irving, of Launceston, was received a piece of inch 
board, cut from the centre of a log of New Zealand Pine, perforated 
like a sieve by the Jredo. 
Specimens of tuffaceous trap-rock and of coarse jasper, &c., 
obtained at Sandy Bay Point, were received from J. L. Burnett, Esq. 
From Mr. Button, of Launceston, were received specimens of the 
irregular hollow ferruginous bodies which are found (associated 
with impressions of leaves of plants, belonging apparently to an 
extinct Flora), throughout the argillaceous diluvium prevailing on 
the Windmill Hill, the Cataract Hill, &c., in that neighbourhood. 
From Captain Hepburne, of St. Paul’s Plains, were received 
specimens of red Hematite, of a very rich quality, and said to abound 
in the vicinity of Mr. Hamilton’s estate there. 
Mr. Milligan placed before the meeting specimens of a fine- 
grained white compact and hard sandstone obtained on the west 
bank of the Tamar, about 12 miles below.Launceston, and near to 
Gravelly Beach. Mr. W. Kay and other members considered it 
scarcely, if at all, inferior in quality and appearance as a building 
stone to that of Ross, and likely to prove of great importance to 
Launceston from its proximity, and the ready means of water- 
carriage existing between the quarry and the town. Numerous 
land-slips on the west bank of the Tamar, near the locality referred 
to, are indicative probably of sedimentary strata beneath yielding to 
the weight of the super-imposed greenstone and soil. 
A sample of fine iron-sand, highly magnetic, obtained upon the 
greenstone at high water-mark in Spring Bay, Tamar River, by Mr. 
Milligan, was submitted. 
The Secretary also submitted specimens of Amianthus, and of 
fibrous and magnetic ore of iron, and of these two substances com- 
mingled, having been found separately and together, forming veins 
in the ridges of Serpentine stretching along the upper portion of 
Anderson’s Creek, toward the Asbestos Mountains, in which neigh- 
bourhood rounded hills of iron conglomerate, passing into a rich 
compact and massive ore of that metal, also occur; while the 
Serpentine, which has a rude tendency to stratification, merges most 
distinctly in the ordinary overlying and amorphous greenstone of 
the country. A very small Pelargonium, common in the fissures of 
the Serpentine rocks, was exhibited ; with the round-leaved hirsute - 
stemmed multifoliate variety found in the crevices of greenstone
