Mr. P. E. Chase exhibited a specimen of a fragment of a 

 steel-rail which had passed through a process of rolling. A 

 broken rail had been placed in the centre of an ingot mould, 

 and Bessemer steel cast around it. The ingot thus formed, 

 was rolled into a new rail, and this second rail was subse- 

 quently re-rolled into a rod of three-quarter inch bolt-iron. 

 The cross sections of the rod still retained the miniature out- 

 lines of the original bar, distinctly marked in the centre.

 laws of magnetic declination.
