effect a tide a whole hour; the swell of the sea when contrary i 0
the tide will do the same : therefore, of what practical use is it to have
formulas for predicting tides or the tidal range with greater accuracy
than that suited for practical purposes when such is the case !” This
question is simply answered. We have gained truth, where for years
we have heen content to remain in enoi ; and if abnormal wind or
swell of the sea w'ould seem to detract from this computed system
such would detract much more from a system which had less truth
and more error in its composition. I would only further say, that in
the year 1842, Dr. Buist, Professor Orlebar, and I think Captain Henry
of the Engineers, were appointed a Committee to erect a tide gauge
at the Observatory, but it was not until after three or four years*
unsuccessful attempts, that the present tide gauge was erected. The
Colaba Land Company promised that, on the completion of their
sea wall, they would further assist the object of the Committee, by
placing a tide gauge at such a place on their ground as the Committee
would point out * but the subject would seem to have been forgotten,
and the promise of the Land Company has never been fulfilled.
I am of opinion, that a suitable place for the establishment of a tide
gauge would he midway up the harbour, and it seems to me there
could be no better position than the Government Dockyard, or a place
a little north of the Custom House Bunder. I have much pleasure
in seconding the vote of thanks proposed to Mr. Burgess by
Lieutenant Fergusson.”
Captain Barker observed, “that local causes should always he taken
into consideration. That for all practical purposes we have found the
liae fables, as published in the Nautical Almanac of ‘ Time of
^ ig -Water at London Bridge’ answer 'very well. The difference
between the time of high-water on full and change of the moon at
