Consequently the above equation would take on the 
following form: 
km. it=hm, 
that is: 
it=h/k=H, 
where H again is another coefficient of proportionality 
and dependent solely upon the units of measure already 
fixed above, and so represents an arbitrary, constant 
numerical value. It follows from this that it is constant. 
And if i in its turn is likewise constant for each specific 
current, t must also be constant; i. e., to each definite 
specificity of current, i, will correspond a likewise deter- 
minate and constant duration of discharge. 
If then, no matter what conditions may induce the 
different discharges of a current of the specificity i, all 
these discharges can have invariably only the same dura- 
tion t, and if this holds also for those which constitute the 
oscillating discharge, then the oscillation itself, which 
consists of a double discharge of which each one has a 
direction contrary to that of the other, as we stated above, 
will have necessarily a very definite and constant period 
of its own which corresponds each time to the particular 
specificity 1 of its respective current. 
It follows that among all the infinite vibrations of the 
different rays from any calorific source whatever, there 
will be certainly present also those which have the same 
oscillatory period as the mnemonic element in the way of 
reconstituting itself, and those synchronous rays will 
then be able to give to the oscillating discharge of the 
latter an impulse which will be added to that received 
through the difference in potential of the pair of accumu- 
lators, and thus to have identically the same effect as that 
which the sinusoidal-alternating, electric, induction cur-
