ON THE POLARITY OF THE DIAMAGNETIC FORCE.

In all these cases the deflections show that the bodies are polar after the manner of 
iron. 
As the complement of the experiments made with diamagnetic liquids, we now 
pass on to the examination of the polarity of magnetic liquids. A concentrated 
solution of sulphate of iron was enclosed in two glass tubes and submitted to 
examination.

A solution of muriate of nickel, examined in the same manner, gave the following 
results : —

In all these cases we have ample evidence of a polar action the reverse of that 
exhibited by diamagnetic liquids. These, I believe, are the first experiments on 
which the action of either liquid magnets or liquid diamagnets upon a suspended 
steel magnet has been exhibited.
