We must, in particular, remember what is meant by the specific resistance, ρ of mercury in the electrostatic system.
The specific resistance of a substance is the reverse of its relative conductivity.
In the same way the specific resistance of any other metal or alloy, when known, may be applied in the formula.
It was to be expected that an animal so treated would have lost its specific resistance to foreign tissues.
At 75° C. the specific resistance falls to about 1025 under similar conditions as to voltage.
Under the most favourable circumstances its specific resistance may approach 1024 E.M. units.
Its specific resistance is given by Ayrton and Perry as more than 1025, but it is probably much higher in selected samples.
For pure aluminum this specific resistance is about 17.7, for soft iron about sixty, and for hard steel about eighty ohms.
