xu. Thus we get (R) at low intensities, equal 20:90—4°°6= 
16:24; and equal 21:99—4:27=17-72; with a Fegiers of 1698. 
From 3°66 to 16°98, the increase is as 1 to 4°64; while the in- 
crease of the full internal resistance, the rie od wire included, is 
only from 5-02 to 21-445, or from 1 to 4 27, for the correspond- 
ing values of table x11. Here again the influence of the intro- 
duction of 100 cm. of copper wire appears as reducing the true 
amount of increase of resistance, and it seems safe to recognize 
this increase as residing mainly if not entirely, within the liquids 
The contrary result exhibited in columns (Cu), (R) and (a), is 
therefore due exclusively to the method of calculation. 
My series of experiments, most of them, show the values for 
the internal resistance, after the general great increase, to de- 
crease for the lowest intensities. This becomes more visible from 
a graphical si stngettia of the course of the internal resistance, 
his circumstance may partly depend on constant faults of the 
observations of reall deflections of the compass needle. But it 
seems certainly to depend partly on the cireuit heitg formed with 
copper conductors. The influence of the intensity upon the in-
