TEMPERATURE IN THE CLIFFORD AMALGAMATED MINES. 285 



not occur again soon, it would be desirable to preserve some 

 permanent record of the highest temperatures observed. The 

 following are the results of Captain Gilbert's observations, made 

 in compliance with my request : — 



At the 224-fm. level, 279 fathoms from the surface, at about 

 120 fms. west of Clifford shaft, the water rising in the bottom of 

 the level maintains a temperature of 123°-5. 



At the 245-fm. level, 300 fms. from surface, the temperature 

 of the water is 125°, the hottest spring we have ever observed. 



I hope this notice, short as it is, will be received as a proof of 

 my warm interest in the Eoyal Institution of Cornwall,
