"C'est fort mal à-propos, qu'on a soutenu que cette répartition inégale
ne sauroit exister, sous prétexte que le globe perdroit son équilibre,
faute d'un contrepoids suffisant au pole méridionale. Il est vrai qu'un
pied cube d'eau salée ne pese pas autant qu'un pied cube de terre; mais
on auroit dû réfléchir, qu'il peut y avoir sous l'ocean des lits & des
couches de matières, dont la pésanteur spécifique varie à l'infini, &
que le peu de profondeur d'une mer, versée sur une grande surface,
contrebalance les endroits où il y a moins de mer, mais où elle est plus
profonde."--_Recherches Philosophiques_, tom. ii, p. 375.--D.
We offered some observations on this topic in the preceding volume, and
need scarcely resume it, as it cannot be imagined that any of our
readers still entertain the belief of the necessity for such an
equilibrium. The object in again alluding to it, is to call attention to
some observations of another kind, which Mr Jones has hazarded in one of
his Physiological Disquisitions. According to him, no such thing as a
southern counterpoise ought to have been expected, for it seems to be
the constitution of our globe, that land and water are contrasted to
each other on its opposite sides. "If," says he, "you bring the meridian
of the Cape of Good Hope under the brazen circle, or universal meridian
of a terrestrial globe, observing that this meridian passes through the
heart of the continents of Europe and Africa, you will find that the
opposite part of the meridian passes through the middle of the great,
south sea. When the middle of the northern continent of America, about
the meridian of Mexico, is examined in the same way, the opposite part
passes very exactly through the middle of the Indian ocean. The southern
continent of America is opposed by that eastern sea which contains the
East India islands. The southern continent of New Holland is opposite to
the Atlantic ocean. This alternation, if I may so call it, between the
land and sea, is too regular to have been casual; and if the face of the
earth was so laid out by design, it was for some good reason. But what
that reason may be, it will be difficult to shew. Perhaps this
disposition may be of service to keep up a proper balance; or, it may
assist toward the diurnal rotation of the earth, the free motions of the
tides, &c.; or the water on one side may give a freer passage to the
rays of the sun, and being convex and transparent, may concentrate, or
at least condense, the solar rays internally, for some benefit to the
land that lies on the other side."--This sort of reasoning, from our
ignorance, is no doubt liable to objection, and Mr Jones had good sense
and candour enough to admit, that the questions were too abstruse for
him to determine. The proper part, indeed, for man to act; is to
investigate what Nature has done, not to dogmatize as to the reasons for
her conduct--to ascertain facts, not to substitute conjectures in place
of them.
