THE TIDES.
Ox the subject of the tides, we may remark that they are effected by the
unequal attraction of the sun and moon, but chiefly that of the latter
object. The times of liigh water do not always answer to the same dis-
tance of the moon from the meridian at the same places, but are vari-
ously aifected by the action of the sun, which brings them on sooner
when the moon is in her first and third quarter, and keeps them back
later when she is in her second and fourth ; because, in the former case,
the tide, raised by the smi alone, would be earlier than that raised by
the moon ; and, in the latter case, later. When tlie moon is in perigee,
or at her nearest distance from the earth, she attracts strongest, and,
therefore, raises the tides most; the contrary happens when she is in
apogee, or at her greatest distance from the earth, because of her weaker
attraction. At new moon, when the moon is in conjunction with the
sun, the tides are raised by the joint attraction of both luminaries, and,
therefore, will be highest; the same is the case at full moon, when the
sun and moon are in opposition ; for whilst the moon raises the tides
under and opposite her, the sun, acting in the same line, raises the tides
under and opposite to him, whence their conjoint effect is the same as
at the change, and, in both cases, occasions wliat are called spring-tides^
But, at the quarters, the sun raises the tides when the moon depresses
them ; and depresses them when they would be raised by the moon : hence,
it is the difference of tlieir actions that produces the tides at the quarters;
and these are called neap-tides. But these tides do not happen till a day
or two after the above times ; because in this, as in other cases, the effect
is not greatest or least when the immediate influence of the cause is
greatest or least, but some time afterward.
The sun being nearer the earth at the beginning than at any other
