They are the result at least of severe and conscientious labour at the original sources of history, but the subject is so complicated and difficult that it may well be feared that the ability to depict and unravel is unequal to the earnestness with which the attempt has been made.

The governor effects the acceleration or retardation of the loosening of the catch actuating the steam valve by means of hard steel projections on the shaft, v1, the position of which, by means of levers, is regulated by the governor, which in its highest position does not allow the lifting of the inlet valve at all.
If W is the net disposable force on the shaft of the engine which works the compressor, v1 the volume of air at the compressor, p1. given by the compressor, and at the temperature of the surrounding air, and p0 the atmospheric pressure, the efficiency of the compressor, assuming the air to expand according to Boyle's law, is given by the well-known formula
a fraction that may be reduced to the simple form if there is no leakage during the passage of the air, because in that cause p2 v2 = p1 v1. Lastly, if W1 is the net disposable force on the shaft of the compressed air motor, the efficiency of this engine will be, and the product of these three partial efficiencies is equal to W1/W, the general efficiency of the transmission.
