Each -of these results in this Table, is the difference of the 
rates when the magnets were applied, and a mean of the 
rates of the chronometers before and after the application of 
the magnets. The rate of the chronometer No. 3, is very 
different from that given in the former Table ; that of No. 4, 
is nearly the same, and does not appear to have been affected, 
as No. 3 was, by the close approach of the magnet. 
Upon the whole, however, it appears that chronometers 
will be generally accelerated (particularly if their balances
