Wheeler notes that the mine furthest from Lake Superior 
gives the highest rise; the others in proportion. All are 
within five miles of the lake, the waters of which are at 
38-8° Fahr., but a continuation of the experiments made at 
the Calumet and Hecla Mine and publication of the detail 
is much to be desired. 
As already mentioned, it is intended that the author’s 
results now approximately given should be but the pre 
liminary settlement of procedure for a much larger series of 
determinations to be carried out as opportunity offers, and 
which must necessarily be extended over a long period of 
time, but which may assist to clear up several outstanding 
points of interest, particularly as regards any possible change 
of rate with depth, and the cooling of rock in mine workings. 
In conclusion, the author must thank several members of 
the Victorian staff of Mine Inspectors, the managers of the 
various mines who have so kindly assisted, and to his 
assistant, Mr. A. M. Henderson, who has entered very fully 
into the pleasure of preparing for and subsequently making 
physical measurements in a very dirty kind of laboratory, 
sometimes as hot as 39° Centigrade, and half full of water.
