PREFACE .
The " HONGKONG ALMANACK " is submitted to the public with much
diffidence. It has been wholly compiled in hours apart from business, with
all the difficulty which naturally attends the want of a practice, ready to the
Professor of Marine Science, Meteorology, or Astronomy, to whom the
work ofpreparing the Tables, would have been comparatively easy. So far as
observations and matériel could be adapted, the London Pictorial
Almanack for this year has been taken as a model. The times of the
rising and setting of the Sun are calculated exclusive of refraction.
Owing to variations in the atmosphere, it follows, that the duration of time
for correction is not always the same in this case, but in the last and first
months of the year, when the sun rises and sets with most obliquity to the
horizon, the rising will be found to be about two minutes earlier, and the
setting as much later than the times given.
The times of high water on each day have been computed simply by the
rules in general use among nautical men, and are therefore only to be looked
upon as approximations. These Tables will however afford a ready refer-
ence to any one disposed to work out for himself the Tide Problem in the
Harbour. The time of high water at full and change of the Moon , as
given by Capt. Sir E. Belcher, is 10h. 15m. with a mean rise of 4 ft. 9 in.
It may be observed, that at the anchorages off the mouth of the Canton
River, the night tides are said to be the highest in the N. E. , and the
day tides in the S. W. Monsoon, and the same phenomena will doubtless
prevail here ; but from Barometrical observations it may be assumed, that
the tides are highest generally in the S. W. Monsoon.
The Weather tables are the mean of a register kept during the last four
years. The Barometer, with Thermometer attached, for a considerable
portion of that time has been stationed in a jalousied anteroom, with a
northerly aspect, about 55 feet above mean level of the sea. It will be
observed that in December the Barometer carries a high range, decreasing
regularly from that month until August, when it again commences to rise
as regularly.
The following Table is interesting, in the exhibition of the different
temperatures of Hongkong, Macao, and Canton. The means of the Macao
and Canton observations have been extracted from a Register, published in
the late Mr Slade's Kalendar, and extended over periods of 10 and 11 years.
