In some works it may be found convenient, aftertreatment of the hydrocarbon gases for tar andammonia, to utilise some of them for illuminating3. (>wing to the inferior description of fuelusually employed in gas producers, as compared withthat used at gasworks, the illuminating power of thehydrocarbon gases may not be found equal to thestandard of the gas supplied by gasworks : but largeror additional burners can be used, and by this meansmanufacturers may almost entirely save their gasbills.

The receiver .having been cleansed with spiritsof wine and washed with water, another sample ofgas from the same producer was taken, with thisdifference, that on its way to the receiver it waspassed through a combustion tube, which w-as heatedby a spirit lamp. The same volume being collectedas before, the weight of gas taken would be somewhatless than on the previous occasion, and had the gason cooling to atmospheric temperature been reducedto the same bulk as previously without deposit of tar,the result would have been considered satisfactory ;but a better result was obtained, for the loss in bulkwas only about 20cc., the receiver being comparativelyfree from tar. It is to be regretted that time wouldnot allow of analyses of the gas obtained under theseconditions to be made, but gas made from Stafford-shire coal, in the Siemens old-type gas producer, hasbeen found to contain less than 35 per cent, of com-bustibl
