From the refnlts of the laft fifteen days obfervations of 
equal altitudes of the Sun, the daily rate of the time-keeper 
was lofing, on mean time, y" ; and on the 16th of April, fhe 
was too flow for mean time, by i6 h o m 58", 45. There was 
found an irregularity in her rate, greater than at any time 
before. It was thought proper to reject the firft five days, 
as the rate in them differed fo much from that of the fif¬ 
teen following; and even in thefe, each day differed from 
another more than ufual.

The variation found on board the fhip, ought to be taken 
for the true one ; not only as it agreed with what we ob- • 
ferved at fea; but becaufe it was found, that there was 
fomething afhore that had a confiderable effect upon the 
compaffes ; in fome places more than others. At one fpot, 
on the Weft point of the Sound, the needle was attracted 
ni points from its proper direction.
