simple process of agitation with those which the 
iron gave by cooling from a high temperature, 
the difference will be observed to be so inconsi- 
derable, as to show that the magnetic action due 
to the latter, is not much superior to that due to 
the former process ; nor indeed at all more. so 
than may be fairly accounted for by the molecular 
movements within the ferruginous masses em- 
ployed (72).
