particular instruction of the sons of the inferior officers of the
arsenals, in the elements of calculation, of geometry, and of design, as
far as necessary for the plans of ships; also the principles of statics,
so as to enable them to judge of the action and effect of machinery. Prizes
of gold medals and special promotions are the rewards of the most deserving
students. Brest was formerly the only port furnished with these schools;
since the peace, however, libraries are forming in each of the others; and
in almost all, cabinets of natural history and botanical gardens are
enriched at every voyage undertaken by French ships, either to foreign
coasts, or to those of the French colonies. An observatory has been given
to Toulon and Rochefort. In both these ports naval museums are formed, in
order to preserve types of the most eminent vessels, whose originals either
have been, or soon will be, destroyed by time. Models of ingenious
machines, representations of interesting manoeuvres, a methodical
collection of raw materials, of tools, and of the product of all the arts
exercised in a dock-yard--Such are the rich materials collected in these
interesting repositories.--_From the French of M. Dupin._


_Antiquity of Locks._

Locks were known in Egypt above four thousand years since, as was inferred
by M. Denon, from some sculptures of the great temple of Karnac,
representing locks similar to those now used in that country. A lock
resembling the Egyptian is used in Cornwall, and the same has been seen in
the Faro Islands; to both which places it was probably taken by the
Phoenicians.--_Quarterly Journal._
