XLVII. Proceedings of "Learned Societies. 



ROYAL GEOLOGICAL SOCIETY OF CORNWALL. 



A HE anniversary meeting of this Society was held in the Mu- 

 seum, Penzance, on Tuesday, October 3, and was, as usual, 

 numerously attended by most of the gentlemen in the western 

 part of Cornwall. Owing to the inconvenience of frequent sit- 

 tings, to members residing at great distances from each other and 

 from the apartments of the Society, as must happen in all as- 

 sociations in the country, the monthly and quarterly meetings 

 have in a great measure given way to the general annual meeting 

 in autumn. At least, for the last few years all the principal me- 

 moirs presented have been reserved for the anniversary meeting. 

 On the present occasion this was well atttuded, and many in- 

 terestini^ and valuable ))apers were read. The following is a brief 

 notice of some of the more interesting of tliese: 1. The Secre- 

 tary, Dr. Forbes, read a very elaborate memoir On the Tempera- 

 ture of Mines ; a subject which of late years has attracted much 

 attention, but which had received little or no notice in Cornwall 

 previously to the institution of this Society. In this paper the 

 author in the first place detailed the result of thermometrical ob- 

 servations, made by himself and others, in numerous mines, as 

 well in (/Ornwall as in other countries; from all of which it re- 

 sulted that the temperature of the air, water, and earth in niines, 

 as shown by the ihermometcr, progressively i^it irregularly in- 

 creased from a few hundred feet beneath the surface to the great- 

 est depths yet attained by the miner : the maKimutn tempera- 

 *ure in the deepest mines of Cornwall (1300 to 1400 feet) being 

 about SO degrees of Pahrciiheit, or 28 degrees above the mean
