| writer's upon tne subject OF sea-Datn-
ing do not agree as to the time at which
the bath should be taken; many, con-
sidering this matter of little impor-
tance, merely suggest that hour of the
day most convenient to each individual.
| In our judgment this is matter of great
| importance, for those who bathe in the
morning before breakfast), besides ex-
posing themselves TO fainting fit, ex-
perience feeling of lassitude or weak
ness, and i'm addition to these injurious
after-effects, there is the exposure to an
atmosphere which is in the morning
more or less damp.
Experience has shown that for the
majority of people the best time is from
seven to eleven in the morning, and the
maximum tonic effects being obtained
then from the fact that the temperature
both of the air and the water is at its
lowest point. For those who are in DELI
cate health or very nervous, and for
children of weak constitutions, the best
time is from eleven in the morning until
four in the afternoon, as between those
hours the temperature of the water stea-
dily increases.
1t is of the utmost importance that
children should be positively forbidden
to bathe after dark. When the sun sets
the breeze from the land is very chilling.
and imparts its freshness to the borders
of the sea, and hence the little ones can
not but be affected injuriously by con-
tact with the water, and no matter what
efforts they make to rub themselves dry,

they will remain all night in condition
which will disturb their slumber, and
may even be the cause of serious disor
ders.
The time chosen for bathing should
Immediately precede or coincide with
that of high water, for then we have the
advantage of easy access to the ocean,
and the least possible exposure in re-
turning to the bath-hOuse; moreover,
the water is then most free from the i'm
purities which it contains at low tide.
Without attempting to demonstrate
the conclusions of kepler, or verify the
theories of Newton upon the tidal phe-
nomena, let us briefly explain why they
take place in the same way at two points
upon the earth's surface which are dia-
metrically opposed. What first attracts
our attention is the ebb and flow of the
waters. These oscillations are period
ical. The water flows to one portion of
the earth during the space of six hours;
this constitutes the rising of the tide;
it then remains stationary for about fif-
teen minutes; it is now called high wa
ter. From this it begins to recede. The
time taken by the water TO return to its
lowest point is about the same as it oc
cupied i'm rising to its highest; this is
termed low tide or full ebb. Afterlre-
naming at this point for quarter of an
hour it again resumes its former mo-
ton, and so continues its oscillations.
During lunar day "a space of twenty
four hours fifty minutes : the time
elapsing between the moon being over
the meridian of place and her return
ing to it, the tides have changed twice.
From this it follows that the tides are
daily fifty minutes later; that is, If on
certain day at any place it be high wa
ter at one p NJ, on the following day
it will be high water at fifty minutes
past one p. NJ, the day after at forty
minutes past two P. NJ, and so on.
