^26. It remains to describe the results of tests of other samples of wrought iron 
and of cast iron, of various steels, manganese steel, nickel, and cobalt. Messrs Jowitt 
and Sons, of Sheffield, were kind enough to supply specimens of pure Swedish iron 
and of steel, with which a number of experiments were made. 
The following results were obtained with a bobbin of Swedish iron, described by 
Messrs. Jowitt as of the “ L®Lancash.” brand, a good Swedish iron made by the 
Lancashire hearth process. The form and size of the bobbin are shown in fig. 11. 
Fig. 11. 
The cones were blunt, and their vertices were at some distance from one another, the 
general effect being similar to that of sharper cones with a common vertex, giving a 
fairly uniform, but not excessively strong, field.
