where 7 is the viscosity and x the specific conductivity of the flowing 
liquid. We ean consider the viscosity of the liquids used to be equal 
to that of water; the conductivity x has been measured in each 
case. The results showed a discrepance with those calculated from 
Kontrauscn’ data of only 1 to 2 10~° Ohm-!; as I measured 
the conductivity of the water I found it to be from 9 107 
to 2 10-* Ohm-t. In the Tables 1, 2, and 4 the conductivities 
are those’ caleulated according to KonrrauscH; only in Table 3, for 
p CIC,H,NH,HCI, I give the results of my own measurements. *) 
To calculate ze, I reduced all the values to c.g.s.-units; therefore 
I had to multiply :

t\, There would be some reasons not to use KOHLRAUSCH’ results and to give 
no correction for the con !uctivity of the water used. For probably, this conduct- 
ivity is not without some influence on the current potential. Still it seems better 
for a correct comparison to reduce all values to the conductivity of the added 
electrolytes only.
