The experiments described in this paper (which were suggested as a result of previous work) were made with the object of discovering whether radiation had any influence upon the rate of combustion of inflammable gaseous mixtures. The gaseous mixtures were contained in a closed vessel and the rate of combustion was inferred from the rate of rise of pressure after ignition by an electric spark. This method was adopted because experience had shown it to be capable of exceedingly great accuracy and sensitiveness.Experimental Arrangements . Two types of apparatus, which it will be convenient to refer to as A and B, were employed in these experiments. In the type A experiments the explosion vessel shown in fig. 1 was used. This consists of a cylindrical cast-iron vessel, 6 inches in diameter and 12 inches long, on to which two end-covers were bolted. A window of fluorite or quartz was placed centrally in the top end-cover, and above it was placed a nichrome wire coil which could be heated by passing an electric current through it.
