INDUCED MACNETTISM 
The curves in Table XXIX. showing the amount of magnetism induced and of the 
alteration of resistance are constructed on the same lines as those in Table XXVIII., 
except that in consequence of the alteration of resistance being much less and the 
induced magnetism greater with iron than with nickel, the alteration is represented on 
a scale of 1 millim. to '3 division of the scale and the induced magnetism on a scale 
of 1 millim. to 1^ divisions of the scale. Each division of the scale represents an 
alteration of resistance amounting to ‘000023 per unit, and if we take the mean of
