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.

A little engine, within a coach, whereby a child may stop it, and secure all persons within it, and the coachman himself, though the horses be never so unruly, in full career; a child being sufficiently capable to unloose them, in what posture soever they should have put themselves, turning never so short; for a child can do it in the twinkling of an eye.
NOTE.
There are but few persons who will disallow the utility of an invention, whose object is to prevent, as much as possible, the frequent and terrible accidents which occur from the present mode of attaching horses to carriages, and other vehicles; that these might in a great measure be avoided, by the application of the Marquis's invention, and a legislative enactment to secure its adoption, there can be no doubt.
To accomplish this very desirable object, a bar, of equal length with the axle-tree, to which is fixed the pole and traces; must be furnished with three iron bolts made to fit a like number of sockets in the axle-tree; and from which, the additional bar may be readily raised, by the application of a common lever: either by the pressure of the driver's foot, or by a string made to communicate with the body of the vehicle. For a chaise the apparatus will be no less simple, with the exception of a small resting bar, or foot, which it will be necessary to discharge by the same lever which sets at liberty the horse, and by this means prevent the sudden jerk, that must otherwise occur in a two wheeled carriage.

How to bring up water balance-wise, so that as little weight or force as will turn a balance, will be only needful, more than the weight of the water within the buckets, which counterpoise and empty themselves one into the other, the uppermost yielding its water (how great a quantity soever it holds) at the same time when the lowermost taketh it in, though it be an hundred fathom high.
