GAS BURNERS OLD AND NEW. A Historical and Descriptive Treatise ON THE PROGRESS OF INVENTION IN GAS LIGHTING; EMBRACING AN ACCOUNT OF THE THEORY OF LUMINOUS COMBUSTION. BY "OWEN MERRIMAN." _Reprinted from the_ JOURNAL OF GAS LIGHTING. London: WALTER KING, 11, BOLT COURT, FLEET STREET, E. C. 1884. W. KING AND SELL, PRINTERS, 12, GOUGH SQUARE, FLEET STREET, LONDON. Transcriber's Note: Figure 11 and Figure 12 are identical. PREFACE. The little work here presented to the public appeared originally in the pages of the _Journal of Gas Lighting_. In the hope that it may thereby become of service to a wider circle of readers, it has been revised and done into its present shape. The object of the writer will be attained if it is the means of lessening, in any degree, the suspicion and prejudice (born of ignorance) which, alas! yet prevail with regard to gas and gas lighting.
