WITH MAGNETISM AND ELECTRICITY.

If we denote the very trifling influence exerted by the thermo- 

 magnetic current upon the result by x, x^, x^^, x^", x^^, and 

 neglect the still smaller differences x—x^, x^ — x^^, a"— .r"'^ 

 ^ni_yiv^ we obtain the following results for the limit-value 

 corresponding to the diamagnetic induction alone, reduced to 

 the normal direction : — 



From this limit- value of the arc of oscillation produced by the 

 uniform distribution of the inductive shocks (by the motion of 

 the bismuth to and fro) over the entire time of oscillation, it is 

 easy to deduce the limit-value which would correspond to a 

 concentration of all the inductive shocks during the oscillation, 

 into a single moment. The value of the arc of oscillation above 



IT 



found, = + 12*644, must for this purpose be multiplied by -, or 



more accurately, taking the influence of the damper into account, 

 with 1*574235, by which we obtain the sought limit- value 



= + 19-905.
