[Class 75 (i).] The gas filling for an electrically ignited flashlight lamp consists of a mixture of 1 volume of carbon disulphide vapour to form 1À5 to 3À5 volumes of nitric oxide at a pressure of from 10 to 70 cm. of mercury. Particularly favourable results are given with mixtures of 1 volume of carbon-disulphide to from 2À25 to 2À75 volumes of nitric oxide.
