leak and the logarithms of the corresponding absolute tem- 
peratures. It shows, while the conduction is produced by 
the same mechanism , a straight-line law. Within these 
limits of temperature, therefore, the current I through the 
gas can be expressed by a formula of the type [=aT", a and 
n being constants, of which the former depends on ‘the units 
employed. For the lower part of the curve n= 24, for the 
upper part n=4l1. . 
When the direction of the field is rever sed the current is
