The magnetic measure of current-intensity is 155370.10° greater than 
the mechanical measure 
Sinee, as already stated, the magnetic measure is to the clectro-dynamic 
measure as 2:1, the electro-dynamic measure of current-intensity is 
109860 . 106 (155370 .106../4) greater than the mechanical measure. 
The magnetic measure is to the electrolytic measure as 1 : 1062, con- 
Sequently the electrolytic measure of current-intensity is 16573 .10° 
(= 106% . 155370. 10°) times greater than the mechanical measure. _
