No. XVIII.
An artificial fountain, to be turned like an hour-glass, by a child, in the twinkling of an eye, it yet holding great quantities of water, and of force sufficient to make snow, ice, and thunder; with the chirping and singing of birds, and showing of several shapes and effects, usual to fountains of pleasure.
NOTE.
That a fountain may be made upon the principle of an hour-glass, and that when the upper division is exhausted, the lower may be elevated by a crank and lever, the fluid passing through the centre of its axis, we may easily conceive; but how a fountain of water can produce snow, ice, thunder, and the singing of birds, is a circumstance not easy to be comprehended.
