counted for by the rapid change in the depth near the edge of the
bank, the former soundings having been taken during a run along the
coast, and their position determined approximately as opportunities
offered of obtaining observations or cross bearings of the land.
The soundings on the present occasion have been obtained by mak
ing a close traverse course from shallow water in shore, to a second
deep cast off the bank to seaward, the distance being measured 'by
Massey’s Patent Logs (corrected for error), and corroborated at every
opportunity both by cross bearings and astronomical observations.
The four self-registering deep sea Thermometers supplied having
proved faulty, I have been unable to obtain further temperatures than
those contained in the following table, which were taken in April 1861.
The surface temperature has been uniform at 69°, and 72° or 3° below
what it was in April.
