_INTERESTING QUESTION._

Whether in the sea there be depths where no creature is able to
live, or whether a boundary be assigned to organic life within those
depths, cannot be ascertained. It, however, clearly appears from
the observations made by Biot, and other naturalists, that fishes,
according to their different dispositions, live in different depths of
the ocean.--_From the German_.

_CATS._

In Kamtschatka, Greenland, Lapland, and Iceland, there are no cats,
nor does the lynx in Europe extend farther than Norway.--Ibid.

_VESSELS MADE OF THE PAPYRUS._

The last number of the _Magazine of Natural History_ contains an
article of great interest, on Vessels made of the Papyrus, illustrated
with cuts, from which it appears that vessels have from the earliest
times, been formed from the paper reed, and that they are at present
in use in Egypt and Abyssinia. The author is John Hogg, Esq. M.A.
F.L.S. &c. whose antiquarian attainments have greatly assisted him in
the elucidation of this very curious subject.

_REMAINS OF LA PEROUSE._[10]

M. Derville, who commanded the Astrolabe, in the lute-voyage
undertaken to search for traces of the expedition of La Perouse,
considers the island, the summits of which were observed fifteen
leagues to windward, by the frigates La Recherche and L'Esperance,
which composed the expedition of Admiral D'Entrecasteaux, in 1793, and
to which the name of the Isle de la Recherche was then given, to be
the identical island, Vanikoro (or Vanicolo) on the shores of which
the remnants of La Perouse's vessel have been found. The geographical
position of latitude and longitude of the Isle of Vanikoro, agrees
exactly with that of the island to which the name of Recherche was
given by D'Entrecasteaux. That island was then confounded with the
number of other islands, which had been seen by the expedition, and
which it had been found impossible to examine in detail.--_Athenaeum_.

_STUDY OF CHEMISTRY._

Numbers there are, far above the lower classes, who still consider the
elements of all things as consisting of earth, air, fire, and water;
an error which classical-learning, no less than the expressions of
common parlance, tends to perpetuate. Let us hope that the days are
at hand, if not already arrived, in which the acquirement of such
fundamental knowledge will be looked upon as at
