95, in which a stout glass tube is provided with a sound cork, B, and also an air-tight piston, D, resembling that of an ordinary syringe.

Fit the cork in the tube while the piston is near the top.

Now, by lowering the piston we increase the capacity of the cavity containing the bag.

As soon as we let go the piston, the elasticity of the bag, being free to act, Movements of drives out the air just taken in, and the piston returns to its former place.

He took a neck in each hand and cracked their skulls together until the whack-whack-whack of it was like the exhaust of a Ford with loose piston rings; and when they fell from his grip, unconscious, he came to my rescue.

He also devised and adapted many new types of engines for marine purposes, having respect to the geometrical character of the connections by means of which a reciprocating motion of the piston may be transformed into a rotary motion of the shaft.

A solo de piston, a violin, a flute, all played by Tahitians, entertained us, and then came the fun.

The only difference between the apparently useless old lumber and scrap iron, piled together in promiscuous confusion, machinery thrown into a heap without the arrangement, and the new building with its powerful engine working smoothly and swiftly for the comfort and wealth of men, was that before the rebuilding, the wheels, the saw, the shafting, boilers, piston-rod, and fly wheel had no definite relation to each other.

But some man picked out all these features of a complete mill and put them into proper relation; he adjusted shaft, boiler, and cogwheel, put water in the boiler and fire under it, let steam into the cylinders, and moved piston-rod, wheels, and saw.

The setting in motion of so powerful an engine is effected very easily by means of an arrangement that permits of introducing into the cylinder, while the piston is in the center of the stroke, a mixture of air and gas whose pressure is sufficient at the arrival to expel the inert products.

These are connected together by a steel piston rod, the top air piston forming a connection for the small end of the connecting rod.

In the cylinder of an air compressor the energy of the piston is converted into molecular motion in the air and the result, or the equivalent, is heat.

If I hold an open cylinder in my left hand and a piston in my right, and place the piston within the cylinder, I here have a confined volume of air at the temperature and the pressure of this room.

If I hold an open cylinder in my left hand and a piston in my right, and place the piston within the cylinder, I here have a confined volume of air at the temperature and the pressure of this room.

Now if I press the piston to a point in the center of the cylinder, that is, to one-half the stroke, I here decrease the distance between the cylinder head and the piston just one-half, hence each molecule of air strikes twice as many blows upon the piston and head in traveling the same distance and the pressure is doubled.

If I instantly release the piston which I hold at one-half stroke it will return to its original position, less only a little friction.

It will be observed that each steam cylinder has an air cylinder connected directly to the tail rod of its piston, so that it is a direct-acting machine, except in that the strains are transmitted through a single fly wheel, which is attached to a crank shaft connecting the engines.

I then set my beans to boil whilst I dusted, and was upstairs waiting, ready dressed, for the sound of the 'Echo's' piston.

He follows back to the piston of the engine and finds the motor there,satisfied that he has discovered in the transference of rectilinear to rotatory motion the reason for the progress of the boat.

The stream must be dammed before it will drive wheels; the steam compressed ere it will compel the piston.
