ANNIVERSARY ADDRESS OF THE PRESIDENT. Ixxvil 
generally. The fifth volume is almost exclusively occupied by an 
elaborate account of the mineral veins of Cornwall, by Mr. Hen- 
wood; and other valuable notices of Cornish and Devonian lodes are 
scattered through the other volumes. Sir Charles Lemon, the 
zealous President of this Society, finding that there was a hesitation 
on the part of many practical men to communicate their observations 
in writing to the Geological Society of Cornwall, (and those who are 
acquainted with the Cornish miner know full well the value of his 
observations, ) has during the last year, and at his own cost, engaged 
the services of Mr. Rundell, the secretary of that highly useful body 
the Polytechnic Society of Cornwall, to obtain information from the 
miners and communicate it to the Society. The experiment has 
been attended with success, and the result has been some interesting 
details, read before the Society, respecting certain peculiar circum- 
stances in Gwinear Consols and Wheal Seaton mines. It is to be 
hoped that the experiment thus tried and found to be successful 
may be followed up by the friends of the progress of knowledge in 
Cornwall, and of the practical Cornish miner. 
Though read in 1846, it is desirable, being now only published, 
to notice the communication to this Society by Mr. Pattison, on the 
geology of the Tintagel district, one of considerable interest, from con- 
taining the junction of the carboniferous series of Northern Cornwall 
and Central Devon with the range of rocks which come up westward 
from the Petherwin district, wherein so many interesting organic 
remains have been detected, and not a few by Mr. Pattison himself, 
In a carefully considered paper the author details the order of suc- 
cession of the rocks, the admixture of igneous products with them, 
and the organic remains detected, remarking respecting the latter, 
on the absence of Trilobites and the rarity of Cephalopods which 
distinguish the Tintagel beds from those found near Petherwin, and 
the entire absence of the remains of fish, such as are found in South 
Cornwall. 
We find Mr. Peach occupying himself as actively as ever with 
organic remains entombed in the Cornish rocks, accumulations which 
not many years since were supposed to be entirely non-fossiliferous. 
His communication to the Cornish Society was this year on the fossil 
geology of Lantivet and Lantioc Bays, near Fowey. It will be in 
your recollection, that last year, being then in Cornwall, Sir Roderick 
Murchison read a paper before the Geological Society of Cornwall 
respecting the probability of the occurrence of Silurian rocks in that 
part of England. His opinion was chiefly founded on the researches 
of Mr. Peach, who had obtained many organic forms, usually con- 
sidered referable to that geological period. Mr. Peach in this com- 
munication enters into further detail on the subject, expressing his 
satisfaction that his views had been confirmed. The subject is one 
of much interest, particularly when we regard the physical structure 
of the part of Cornwall noticed, and trace the run of its beds. It 
is more particularly so when we examine the district generally with 
reference to its connection and relative position as regards the Ply- 
mouth limestone and the run of the rocks towards Torbay and
