XXIUI.—Remarks on a Collection of Geological Speci- 
mens made in Tasmania. By Tuomas Moore, Lsg. 
[Read May 11th, 1858.] 
Uron the occasion of a former visit to Van Diemen’s Land 
some few years ago, and during various excursions then taken 
through the country, I made a large collection of Geolo- 
gical Specimens; and returning afterwards to England, I 
presented a selection, of what I considered the most valu- 
able portions of them, to Mr. Thomas Winsmore Wilson, 
of Barnsley, Yorkshire, a practical geologist of great re- 
pute, and this gentleman kindly furnished me with a minute 
description of each specimen. 
Most of Mr. Wilson's remarks are so well worthy of notice 
here, and particularly so as showing forth the mineral 
wealth of this Island, that I haye much pleasure in the 
opportunity now afforded me of laying them before the 
Members of this Society, for the benefit of the community 
at large. 
I wish particularly to draw attention to the fact that very 
rich tin ore was found among the specimens which I pre- 
sented to Mr. Wilson. 
The Argus, Melbourne newspaper, of April 5th, has an 
interesting letter addressed to Mr. Cropper of Melbourne, 
by Mr. Stephen, Vice-President of the Geological Society 
in that city, announcing thé discovery of the same valuable 
mineral in the vicinity of the Ovens diggings, Victoria. 
The following is an extract from Mr. Wilson’s letter 
addressed to me :—
