LXXn. An Account of the Observatio7is and Experiments on 

 the Temperature of Mines, 'which have recently been made in 

 Cor7rjcall, arid the North of England ; comprising the Sub- 

 stance of various Papers on the Subject lately published in 

 the Transactions of the Royal Geological Society of Corn- 

 loall, afid other Works. 



A SERIES of investigations respecting the temperature 

 of mines has for several years past been carried on 

 in Cornwall, under the direction, principally, of Messrs. 

 R. W. Fox and M. P. Moyle, members of the Royal Geolo- 

 gical Society of that county; and the results of their observa- 

 tions have partially appeared, from time to time, in the An- 

 nals of Philosophy, and in some other works. Complete views, 

 however, of the results obtained by each of those gentlemen, 

 with others obtained by Dr. Forbes, late Secretary of the 

 Society, have recently been published in the second volume 

 of its Transactions; and, as the subject is one of great 

 interest and importance, we shall present our readers in this 

 article with a compressed statement of the whole ; appending 

 to it abstracts of Mr. Fox's last paper, which time did not ad- 

 mit of being published in the Transactions, and Mr. Moyle's 

 reply to that and to the former statements of Mr. Fox and 

 ' Xx2 Dr.
