INTRODUCTION OF LIGHTING BY COAL-GAS. 2o 



Gas-meter, patented by Mr. Clegg in 1834, is universally adopted in Paris, and 

 is at present undergoing alterations ; consequently any description of it would 

 in a short time become useless. As a philosophical instrument, it is one of the 

 most beautiful construction ; as a gas-meter, its action is perfectly correct and 

 never-failing ; but it has not been adopted in England, and therefore I shall 

 be silent upon its merits.
