164 E. H, Hali—New Action of Magnetism 
galvanometer. This latter effect produced a deflection of only 
a few mm. and could not have masked any considerable action 
of the kind looked for. 
e first part of this experiment then shows our main fact, 
viz: that in a conductor subjected to the given conditions a per- 
manent electromotive force is at once established which has a 
direction of the magnetic force, or at least none of the same 
order of magnitude as that described above. 
e third experiment to be described was made at the sug- 
gestion and desire of Professor Rowland. It was to test for an 
action of the magnet on the lines of static induction in glass. 
A thick piece of plate glass about four cm. square was taken and 
a hole about four mm. in diameter was drilled through each of 
the four lateral faces. These four holes were all directed to-
