A number of these alloys are made by Mr. Paillard. The composition 
of four described by him in his U. S. patents, and numbered for conve-

The complete masking of the paramagnetic properties of some of the 
ingredients of these alloys is of considerable interest, and would seem to 
indicate a true chemical union of their constituents. The most interesting 
results of my experiments, however, were those in which it was estab- 
lished that no matter of what materials the balance wheel or hair spring 
may be made, provided they are conductors of electricity, their move- 
ments through a magnetic field, when the moving masses properly cut 
the lines of force, must result in a change in their rate of movement, and 
consequently in a change in the rate of the watch ; or, briefly, it was es- 
tablished that @ watch placed in a magnetic field acts like a dynamo-elec- 
tric machine. 
The amount of this action is exceedingly small. In order to detect it, 
a very powerful magnetic field must be employed, and the watch sub- 
jected to its influence for an hour or more,
