Particularly for cold weatherservice this is a most satisfactory manifold, for the mix-ture is maintained at a reasonable temperature while information and until it passes into the cylinders. The mani-fold shown in Fig. 22 is certainly an improvement on thepreceding one, for the length of the gas passages isreduced. In order to secure successful and economical Fi£. 24
