Abstract
IN looking back to the achievements of the past half-century, few domestic improvements will strike the observer more forcibly than the advances made in the development of light from coal gas. In the early fifties the metal flat flame and argand burners were looked upon as so satisfactory and so little likely to find a rival, that practically no efforts were made to improve them, and it was only in 1852 when the late Sir Edward Frankland first made his double chimney argand—afterwards known as the Bowditch burner—in which he led the air supply down between two glass cylinders surrounding the flame, and so utilised some of the heat which would otherwise have been wasted to heat the air supplied to the flames, and found as the result a distinct increase in illuminating power, that the idea arose that it was possible to obtain more than the two to three candles of light per cubic foot of gas consumed which the best burners then gave.
