antimony, though still pulverable in a mortar. When one- 

 fourth of the mass is nickel, the fracture is very compact, and 

 not unlike that of fine steel, but of a lighter colour. With 

 these proportions the alloy is somewhat malleable, and can 

 be cut by a cold chisel. 



65* From a retrospection of the facts developed by these 

 researches, in connection with those previously known, we 

 are led to observe a material difference in the magnetic cha- 

 racters of bodies when in their simplest or natural condi- 

 tions ; and that these natural magnetic characters become 

 considerably modified when the simple or elementary bodies 

 are variously combined ; some simple bodies losing their natu- 

 ral magnetic properties, and others displaying a new magne- 

 tic action of which, before combination, they appeared to be 

 destitute. Under these circumstances, it would be difficult 

 to ascertain the line of demarcation between those bodies 

 that are naturally and separately magnetic, and those that 

 are not. Probably the safest way would be to allow all bodies 

 to possess more or less of the magnetic character, and to 

 classify them into those that are palpably magnetic, like iron 

 and nickel, and those that are but obscurely magnetic, or 

 whose magnetism is not detectable in their individual states, 

 but which become magnetic by combination. 



66. Provisionally, therefore, we might venture to call the 

 former class Sapho^ magnetics, and the latter class Asapho\ 

 magnetics, 



67. Sapho-magnetics might be conveniently subdivided in- 

 to MonoX magnetics and 8uno% magnetics, according as they 

 consist of individual or of compound bodies. Then, as we 

 have many bodies which counteract the highest magnetic 

 powers of simple bodies, these might be called Kato-mag- 

 netics\ because many of them, if not all, have the power
