Hopkinson writes: '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 the 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" [see Philosophical Transactions A, volume 180].'

Annotations in pencil and ink. Includes 16 pages of graphs of experimental results.
