Mr. Scoresby's experiments and observations on the 
4 more very strong blows - - 73 grains. 
10 more ----- 186 
8 more - - - - 246 
6 more [[wire began to bend] - - 326 
4 more ------ 32 6 
No. VII. 
The wire last used ( S £ ii ) , not being regularly softened , was 
again put through the fire, and all its magnetism destroyed. 
a. Simple process. 
By 2 strong blows only, it was now made to lift 186 grains. 
4 more ------ 24 6 
30 lighter blows - 326 
20 more [[began to bend] - 326 
b. Compound process. 
After 20 blows on I ii, (the magnetism before given not 
being destroyed, though much weakened by straightening 
it) it lifted 32 6 grains much more freely than before, but 
refused the next larger nail of 389. grains. 
No. VIII. 
A piece of the same wire as that used in the last experiment, 
2t inches in length . [S t iii.] 
a. Simple process. 
After being repeatedly hammered by this process, its 
lifting power was raised to 56 grains. 
Hammered several times, at intervals, for a minute or two 
together, without increasing its power to lift 88 grains.
