This table for longer spark lengths contains the results of Voege, Ann. der Phys. 14, 1904, using alternating current
it" electrodes, and the results with steady potential found in the recent very careful work of C. Miit-



and "dull point

ler, Ann. d. Phys. 28, p. 585, 1909.




The specially constructed elec-
trodes lor the columns headed
" cup electrodes " had the form of
a projecting knob 3 cm. in diame-
ter and having a height of 4.5 mm.
and 1.5 mm. respectively, attached
to the plane face of the electrodes.
These electrodes give a very satis-
?en the
voltage
iroughout the range studied.



<3cm.> V ihese electrodes give a very s
J factory linear relation between
I spark lengths and the volt
' throughout the range studied.

Determinations of the dielectric strength of the same substance by different observers do not agree well For a dis-
cussion of the sources of error see Mos'cicki, Electrotechn. Z. 25, 1904.

For more detailed information on the dependence of the sparking distance in oils as a function of the nature of the
electrodes, see Edmondson, Phys. Review 6, p. 65, 1898.

portional to the density.
