Acetylene.

Additional information : concerning the use of acetylene is furnished mthe simple method devised by, A. E Murphy, of Essex, England, for ..blow-' ■ pipe work and in atmospheric burners, and communicated by him to Nature. Ah ordinary Bunsen, burner of special -dimensions is employed, with a very small jet for the gas—this, for the laboratory—and the burner tube is covered with cap -to exclude dust: when the burner is not in user Tb© acetylene is generated under about 9in or. Bin water, pressure ; with 6in pressure a perfectly clean flame of good size can be obtained, the flame burning steadily and noiselessly, with a consumption of about one oubic foot of the gas. per hour. The flames are found to be possessed of great-heating power, one volume of acetylene being for practical purposes nearly twice as effective as one volume of ordinary gas This, it is declared, mesns an immense saving of time in all heating operations, and in many caßss the use of the.blowpipe can be dispensed with, the burner alone being quite hot enough for small fusion's and simple glass making operations.
