208 Mr. Scoresby’s experiments and observations on the 
The experiment being repeated the next day, (July 15), 
when the bar, I iv, had become more magnetic by use, 
the wire readily lifted - 389 grains. 
A few more blows raised its power to - 482 
Additional hammering - - 482 + 19 = 501 
Experiment repeated, July 16, 482 + 51 = 533 
b. Compound process. 
After a few smart blows the lifting power of this wire was 
now raised to - 482+103 = 585. 
Process continued by a number of blows 482 +122 = 604- 
After a variety of repetitions of this process, the large 
bar, I iv, having become strongly magnetic, the lifting 
power of the wire was augmented to 482 + 187 = 669 
grains, being above four times its own weight. 
No. XV. 
£July 14 to i8^ 
A new untempered wire (S u iii ),frdm the same piece as St\, 47 
inches in length ; weight, 150 grains, 
a. Simple process. 
After a few smart blows, this wire lifted - 246 grains. 
On repeated hammerings, its lifting power 
was augmented to - - - -326 
The process repeated the next day, - - 389 
Again repeated on another day - - 482 
b. Compound process. 
On the first application of this process, by a few hard 
blows, there was no accession of power, the lifting power 
continuing at - - - - - 482 grains.
