214 PECULIARITIES IN THE MAGNETISM 
19. It appears from the above paragraph, that 
at the time of writing my third memoir, I con- 
sidered that the /ateral translation of the magnetic 
poles was still wanting to complete the series of 
investigation which I had undertaken: and I have 
now the satisfaction of stating to this society, that 
I have been successful in producing the Jateral 
translation of the poles, and of observing that 
they travel from the point of heat, in accordance 
with the same law as is observed by the longz- 
tudinal translations, or those in the line of the 
axis. 
20. For the purpose of obtaining the Jateral 
transplacement of the magnetic poles, by the 
influence of heat, it appeared necessary to employ 
a magnet of more than the usual breadth: and 
my first experiments, in this inquiry, were made 
on the blade of asaw, previously magnetized. I 
was perfectly successful in the first trials, produc- 
ing a lateral transplacement of one of the poles, 
to a sufficient distance from its original position 
to cause a deviation of the needle amounting to 
2°, by the simple application of the flame of a 
small spirit lamp to one side of the saw, directly 
opposite to the pole.
