be produced, if the bottle be filled
with water, and the vessel with wine.

_The Globular Fountain._

Make a hollow globe, of copper or lead, and of a size adapted to the
quantity of water that comes from a pipe (hereafter mentioned) to
which it is to be fixed, and which may be fastened to any kind of
pump, provided it be so constructed, that the water shall have no
other means of escape than through the pipe. Pierce a number of small
holes through the globe, that all tend towards its centre, and annex
it to the pipe that communicates with the pump. The water that comes
from the pump, rushing with violence into the globe, will be forced
out at the holes, and form a very pleasing sphere of water.

_The Hydraulic Dancer._

Procure a little figure made of cork, which you may dress as your
fancy dictates. In this figure place a small hollow cone made of thin
leaf brass.

When the figure is placed on a jet d'eau, that plays in a
perpendicular direction, it will be suspended on the top of the water,
and perform a great variety of amusing motions.

If a hollow ball of very thin copper, of an inch diameter, be placed
on a similar jet, it will remain suspended, turning round, and
spreading the water all about it.

_A Person having put a Ring an one of his Fingers, to name the Person,
the Hand, the Finger, and the Joint on which it is placed._

Let a third person double the number of the order in which he stands
who has the ring, and add 5 to that number; then multiply that sum by
5, and to the product add 10. Let him next add 1 to the last number,
if the ring be on the right hand, and 2 if on the left, and multiply
the whole by 10: to the product of this he must add the number of the
finger, (counting the thumb as the first finger,) and multiply the
whole again by 10. Let him then add the number of the joint, and,
lastly, to the whole join 35.

He is then to tell you the amount of the whole, from which you are to
subtract 3535, and the remainder will consist of four figures; the
first of which will express the rank in which the person stands, the
second the hand, (number 1 signifying the right, and 2 the left,) the
third number the finger, and the fourth the joint.--For example:

Suppose the person who stands the third in order has put the ring upon
the second joint of the thumb of his left hand; then,

The double of the rank of the third person is 6
To which add 5
