The following Papers were read : 



I. " Magnetic Properties of Alloys of Nickel and Iron." By 

 J. HOPKINSON, D.Sc., F.R.S. Received April 17, 1890. 



Eight different alloys have been examined, distinguished here by the 

 letters of the alphabet. All the samples were given to me by 

 Mr. Riley, of the Steel Company of Scotland, who also furnished me 

 with tho analysis , given with the account of the experiments with 

 each sample. 



The methods of experiment were the same as were detailed in 

 my paper on " Magnetic and other Physical Properties of Iron at a 

 High Temperature." The dimensions of the samples were also the 

 same. For this reason it is unnecessary to recapitulate the methods 

 adopted. I confine myself to a statement of the several results, 

 dealing with each sample in succession.
