Capitolo 8

you position to the third being of similar quarter, unless the
moon would be then on the side of the more earth next to B, The
tide to An is combined of tall water of the solar tide
overlapped on low water of the lunar tide, so that the sea
it is to a level taller than in the case of the low water of
spring tides. The tide to D is due to the attraction of the
the centrifugal excess of centripetal strength lands on the moon above
forces, and the tide to B is due to the excess of centrifugal
forces on centripetal strength. These are known as tides of "neap",
and, as the sun is acting in opposition to the moon, the height
of tall water less I am notably that to the duration in spring
tides. The tides are continually varying among these extremeses
according to the changes in the strengths that attract, but the
joint tall lies of tide more next to the crest of the lunar one that of
the solar tide. It is obvious that, if the strength that attracts of
the sun and moon were equal, the height of spring tides is able
is double that because of every body separately, and that there
it would not be variation in the height of the sea to the duration of
tides of neap.

Now it will be of interest to consider the smaller movements of
the sun and it lands on the moon, as they also strikes the reason tides of
the changes that they causes in the attractive strength. During the
revolution of the circle of earth the sun the following positions
of the point on the earth that is more neighbor to the sun will form
a diagonal line through the equator. To the spring equinox
(March 20) the equator is vertically under the sun that then
you reduce to the south up to that the solstice in summer (June 21), when
it reaches his/her maximum southern declination. It stirs then
toward north, passing again vertically on the equator to the
autumn equinox (September 21), and you bring his maximum
northern declination on the solstice in winter (December 21). The
various declination from approximately 24 degrees above than to 24 degrees
under the equator. The sun is more next to the Southern ocean,
