Remarks on Seasons, Iites, Wids, &c.
Having in my formcrremarks introduced
variety of facts, proving that the How OF
waters in the oceans are in anticipation OF
the moon in her passage from east to west
vet as most of the examples which have
given, relate to the sea coast bordering on
the United States, and may be thought by
some too limited an account whereon to re-
", | have therefore, in order to remove all
doubts upon the subject, selected from the
British and American tide tables, sundry O.
ther cases more directly under the moons
path-for instance, at Cape Blanc in Africa,
high water at the full and change of the
moon is at Oh. 45m. Senegal river entrance
is at 1oh. SOM; Sierra Leon in Guinea, 8h
15m.-so that in taking the whole of the
Westerly Coast of Africa and summing up
the result OF high water at the different
Capes and at the entrance of rivers, we shall
find that high water preccdcs the moon sew
eral hours-though on the north and south
sides Of the Continent, high water is in the
rear of the moon several hours. The rea-
son of this Gas explained in my last essay\ is
no doubt owing to the moons projectile
forces, herself travelling over land, necessa-
rily propels the waters from the respective
shores. Those waters thus driven some
times produces current-this current takes
the direction of those channels which border
on and near the coast, for / think no person
can object to this idea; viz, that all the O.
ceans on the globe have their respective
channels-the greater Of these are iatersec-
ted by those of less magnitude, and which
are formed and kept open by the streams
issuing from the mouths of rivers so that by
forming just estimate OF the depth OF the
waters and their extent in length and breadth
we cannot be much deceived with respect
to the time of high water at any given place.
If we suppose line of longitude from Cape
Verd in Africa, to Cape Cayenne, in South
America, which embraces several thousand
miles of deep waters, VIC shall find on eX-
amining the tables of tides, that the gravity
of the moon, and in the absence of the moon
and sun, the gravity of the atmosphere alone
ouickcns the flow of the tides six hours at
Caycnne-from which circumstance think
it is infcrable, that if the moons and atmos-
phcrc's influences were not disturbed by
continents, islands, and shoals, tides would
uniformly preccde the moon about hours
Consequently there would be low water al
WAYS under the moon and under the atmos-
pherc at the opposite side of the earth at the
same time. There are many people no doup'
who having received their tuition from New
ton, Hershel and some others, will condemn
the idea of projectile, or propellns and re-
pclling forces as having any effect upon the
tides, and the principle reason why they
will so condemn, is because 1t IS written ina
the sun. earth, and moon, do mutually attrac
each other, and that the attraction betweel
the moon and the waters arc very great, III
