Everything was measured -- the gas by a 60 light, and the air by a 300 light meter; the indicated horse power, by a steam-engine indicator; the useful work, by a Prony brake; the temperature of the water, by a standard thermometer; and that of the escaping gases, by a pyrometer.

Calculations are greatly facilitated, and the value of tests can be ascertained quickly, if the constant of the brake is ascertained; then it will be simply necessary to multiply the number of revolutions and the weight at the end of the lever by such a constant, and the product gives the horse power, because, with a given Prony brake, the only variable quantities are the weight and the speed.

Five different trials were made at varying speeds of the driving shaft; the initial work on this shaft was measured by a dynamometer, and the available energy of the shaft of the receiving machine was ascertained by a Prony brake; the other results of the experiments were deduced from the constants of the machines and from galvanometric measurements.

Tests with a Prony brake showed that the motor developed 128

Before fixing a motor in its final position, it should also be tested for power with a dynamometer, and for this purpose a Prony brake answers very well.

The evening before the day fixed on for the first sitting, Modeste, the elderly maid of the first Madame de Nailles, who loved her daughter, whom she had known from the moment of her birth, as if she had been her own foster-child, arrived at the studio of Hubert Marien in the Rue de Prony, bearing a box which she said contained all that would be wanted by

Prony, with his hair nearly in my plate, was telling entertaining anecdotes

Maria Edgeworth 1905

"Prony, as like an honest water-dog as ever; Biot ( 'et moi aussi je suis père de famille'), a fat, double volume of himself – I could not see a trace of the young père de famille we knew – round-faced, with a bald head, a few black ringlets, a fine-boned skull, on which the tortoise might fall without cracking it."

He partially forgot the keen wound given to his self-love by the time that he found himself close to Parc Monceau approaching Rue Prony.
