206 Mr. Scoresby’s experiments and observations on the 
No. X. 
New Steel wire S t\v ( softened), not at all magnetic. 
5 hard blows struck on this wire whilst held on the equator, 
or middle of the bar I i, (this bar lying horizontally in- 
stead of standing vertically as in the other experiments ) 
produced only a lifting power of 4 grains 
No. XI. 
Similar wire to the last, S tv, not in the least magnetic. 
5 blows struck on this wire, whilst held upon I i, both the 
bar and wire being in a vertical position, and both being 
freed from magnetism immediately before the experi- 
ment excepting the magnetism of position, occasioned a 
lifting power of 37 grains, and that with difficulty. 
No. XII. 
A wire similar to the last in every respect, S t vi ; not in the 
least degree magnetic. 
a. Simple process. 
5 blows were struck on this wire, held in the same posi- 
tion as in the last experiment on I i, the bar I i having 
been previously struck 20 hard blows with the large 
hammer, through the medium of I iii, by which treat- 
ment a lifting power was given to the wire of 1 12 grains. 
The magnetism of the wire being destroyed again, the 
same experiment was repeated, and somewhat harder 
blows struck, by which, with 5 blows, a lifting power 
of 186 grains was obtained.
