bodies. Of late his name has been little connected with ship design; but
his interest in the subject was unabated.

In 1870 M. Dupuy devoted a large amount of time and thought to perfecting
a system of navigable balloons, and the French Government gave him great
assistance in carrying out the experiments. It does not seem, however,
that any sufficient success was reached to justify further trials. The
theoretical investigations on which the design was based, and the
ingenuity displayed in carrying out the construction of the balloon, were
worthy of M. Dupuy's high reputation. The fleet that he constructed for
France has already disappeared to a great extent, and the vessels still
remaining will soon fall out of service. But the name and reputation of
their designer will live as long as the history of naval construction is
studied.--_The Engineer_.
