Next to a supply of boatmen our attention was directed towards the
procuring of a house conveniently situated for trying the instruments and
examining the rates of the chronometers. Mr. Geddes kindly offered one of
his which, though in an unfinished state, was readily accepted, being

of the instrument was changed from the east to the west, the amount being
the greatest when it was placed with the face to the west. But on the 8th
a westerly wind caused a cloudless sky which enabled us to place the
