From the results of the last fifteen days observations of equal
altitudes of the sun, the daily rate of the time-keeper was losing,
on mean time, 7"; and on the 16th of April, she was too slow for mean
time by 16^h 0^m 58",45. There was found an irregularity in her rate
greater than at any time before. It was thought proper to reject the
first five days, as the rate in them differed so much from that of the
fifteen following; and even in these, each day differed from another
more than usual.

_Variation of the Compass._

6. \P.M./ Mean of four Needles\ 19 38 46 /

The variation found on board the ship ought to be taken for the true
one; not only as it agreed with what we observed at sea, but because
it was found that there was something ashore that had a considerable
effect upon the compasses; in some places more than others. At one
spot, on the west point of the Sound, the needle was attracted 113/4
points from its proper direction.
