 One wire 100° C, the other 8° C.

w signifies icarm; c, cold; h, hard; s, soft. 



The discussion of this table would give rise to some interesting 

 speculations, which, however, we forbear dwelling upon, as M. 

 Magnus himself has not thought proper to introduce them — 

 doubtless because he considers the subject not yet ripe for such. 

 We shall therefore content ourselves with the expression of a 

 hope, that results so suggestive will receive at the hands of their 

 discoverer the development of which they seem capable. 



Experiments such as these are always valuable as points of 

 reference; we therefore introduce a second table, in which a 

 temperature of 250° C. was applied. 



One wire 250° C, the other 8° C.
