By examining the several rates of the time-keepers F and G, 
it appears, that they lost by having XII turned from N. to E. ; 
gained by being turned from E. to S. ; lost from S. to W. ; 
and gained from W. to N. ; the changes from plus to minus 
being alternate, as shewn in the succeeding Table.

In another set of experiments with chronometer H, placed 
on the middle of an irregular eight-sided magnetic plate, the 
changes were precisely the reverse of those recorded in the pre- 
ceding Table, as particularly shewn in the next Table.
