Analogies Concerning Life 145 



different and some the same, whenever a 

 fresh individual or magnet is brought into 

 being. 



All this can be said concerning the old 

 process of magnetisation the process as it 

 was doubtless familiar to the unknown dis- 

 coverer of the lodestone, to the ancient users 

 of the mariner's compass, and to Dr Gilbert 

 of Colchester, the discoverer of the magnet- 

 ised condition of the Earth. 



But within the nineteenth century a fresh 

 process of magnetisation has been discovered, 

 and this new or electrical process is no longer 

 obviously dependent on the existence of 

 antecedent magnetism, but seems at first 

 sight to be a property freshly or spon- 

 taneously generated, as it were. The process 

 was discovered as the result of setting 

 electricity into motion. So long as elec- 

 tricity was studied in its condition at rest on 

 charged conductors, as in the old science 

 of electrostatics or frictional electricity, it 

 possessed no magnetic properties whatever, 



nor did it encroach on the magnetic domain :
