Whirlpool Reach, and measured eleven and a-half feet in length. 
Also two fine specimens of Trigonia, dredged up on the oyster bank 
two miles below Point Rapid, in the Tamar, in about three fathoms 
water. Also the dried carcass of a fish (not named), allied to the 
shark, from the Tamar, near Middle Island. 
Mr. Wheeler, of Port Sorell, forwarded to the Museum specimens 
of lignite taken from a well at a depth of ninety-four feet, together 
with nodular iron pyrites and fragments of vesicular trap rocks 
from the same depth. Alsoa specimen of iron ore (Hematite?) 
said to be from the mouth of the Leven River, anda few Venus 
shells from the beach there. 
The Superintendent of the Gardens reported having forwarded 
to N. W. Lewin, Esq., at Wellington, a case containing fifty-seven 
species of plants, to be returned with indigenous plants of New 
Zealand. 
Mr, T. Browne, of Macquarie-strect, submitted a sample of fine 
pipe-clay from Surge’s (?) Bay, in the mouth of the Huon River. 
The Secretary placed on the table specimens of lignite, anda 
substance like semi-decomposed kino, with fossil shells of Mytilacea, 
obtained about thirty feet down ina shaft recently sunk by Mr. Ralston, 
upon a flat on the west bank of the Tamar, two or three miles below 
Point Rapid. Also specimens of shells (mineralized with iron) 
resembling Nucule and Solenacee, from the nodular clay ironstone 
beds, which, interlaid with clayey sandstone and with carbonaceous 
and slaty clays, crop out under greenstone, continuously along the 
river’s bank downwards from Point Rapid to the vicinity of Middle 
Island, and upwards at intervals through Whirlpool Reach to Spring 
Bay, where the ferruginous shells again occur abundantly, it is said, 
on its eastern shore. The Secretary described the progress of three 
sinkings recently made by Mr. Reed on the western side of Whirl- 
pool Reach in search of coal, and ventured the opinion that the 
whole of the sedimentary beds disclosed along the Tamar, from 
Spring Bay to Middle Island, covered though they are with heavy 
and extended masses of greenstone, will prove to be éertiary. 
The Secretary drew attention to the close resemblance and probable 
identity of the fossil shells in certain beds of clayey conglomerate 
at the Mersey River—in the grit and arenaceous clay-beds over the 
limestone in the West arm of the Tamar—in the limestone at Maria 
Island—at St. Paul’s Plains—Moulting Bay, and East Bay Neck,—
