In 1801, a plan was proposed by a M.Le Blond for lighting a part of the streets of Paris with gas.

Murdock actively resumed his experiments; and on the occasion of the Peace of Amiens in March, 1802, he made the first public exhibition of his invention.

The whole of the works at Soho were brilliantly illuminated with gas.
The sight was received with immense enthusiasm.

There could now be no doubt as to the enormous advantages of this method of producing artificial light, compared with that from oil or tallow.

In the following year the manufacture of gas-making apparatus was added to the other branches of Boulton and Watts' business, with which Murdock was now associated,--and as much as from 4000L.
