MAGNETIC CONSTANTS. 761 



1294. SPECIFIC INDUCTIVE POWERS. The duration of the 

 charge has so great an influence that it is difficult to obtain with 

 exactitude the 'value of the specific inductive power, especially for 

 solids or liquids. In most cases the following numbers can only 

 be considered as approximate values. 



SOLIDS AND LIQUIDS. 



1295. MAGNETIC CONSTANTS. The magnetic magnitudes are 

 measured in C.G.S. units, which lead to much simpler numbers 

 than the practical units.
