It extends, in the form borders of which it is situated, in Switzerland, as of a crescent, chiefly through the Canton of Zurich, but also of the Canton which contains both the town and partly also between those of Schweitz and St. Gall, the lake.

But the term paradox is not properly apperceptible but that resulting from gravity, which plied here, since by tracing the operation of the law tends to confine the fluid to the bottom of the vessel. of equal pressure, we see how directly the effect just No upward pressure whatever is perceptible.

this, every effort to press down the small piston ope-
rates in pressing up the larger one, and the amount of
this upward pressure depends on the comparative,
dimensions of the two pistons. If the smaller one is
one inch in diameter, and the larger six inches, it
presents thirty-six times as much square surface,
every inch of which is pressed upwards with the same
force as the small piston is pressed downwards. Now,
if the piston be pressed down with the force of 20
lbs., (an inconsiderable force with such a leverage as
a pump handle affords) the large piston will be
pressed upwards with a force of 20 x 36 - 720 lbs.;
so that if were the lower board of a press, it would
act on the body between it and the upper board with
a force of 720 lbs.

When once the principle of a machine is well understood, improvements in the details may be expected. Mr. Bramah has availed himself of the beautiful hydrostatic law which we have been considering, to construct a press, the power of which is so extraordinary, that a mere statement of it, without explaining the principles on which it rests, would scarcely be credited. The small pipe of the forcing pump is frequently about half an inch in diameter, and of the cylinder twelve inches, so that a section of the large piston contains 576 times as large a surface as a section of the smaller cylinder. The pump is so strongly made, that a force of one ton may be applied to the handle, so that the small piston is pressed down with that force, and the larger piston is pressed up with a force of five hundred and seventy-six tons. We merely give this statement in figures, to show more clearly the power of the instrument. The actual power produced may be in any ratio we please,-limited only by the strength of the materials of which

the press is made. We have seen a bar of iron cut The reader will now be in a condition to under- through by a Bramah press not much exceeding a stand the action of a hydrostatic press, of which a
