Here Mr. Wilson’s remarks conclude, and if I could 
have produced duplicates of the various specimens which he 
has so ably described, it would have been satisfactory ; but 
the fact is, I had presented the residue of my collection to 
the Manchester Geological Museum before receiving the 
notes I have just had the honour of reading. 
Your worthy Secretary, Dr. Milligan, and others here 
who take an interest in geological pursuits, will at once, 
however, recognize the localities and nature of many of the 
specimens described; and of those which are not -marked 
T have so vivid a recollection, that it will be in my power to 
point out the positions in which the principal portion of 
them were found. : 
You will perceive that amongst the 36 specimens men- 
tioned, there are some yaluable minerals ; and if Mr. Wilson 
has reason to be proud of the collection, how much more 
ought you to be proud of the country which produces them ! 
No mention has been made here of the coal measures of 
the island, which have, however, engaged my attention, and 
may on some future opportunity form the subject of a paper
