(From the London Engineer.) The accompanying illustrations show a new type ofquadruple-expansion engine lately built by Fleming &Ferguson, of Paisley, Scotland. The illustrations aretaken from the drawings of small engines of about , which are to be placed in a yacht being built for Douglas. We may mention, however, that & Ferguson have now in hand engines of a sim-ilar type, which are to indicate 1,800 Referring to our illustrations, fig. i is an end elevation,fig. 2 a front elevation, and hg. 3 a plan.

In the engine in ques-tion a prolongation of this arm is used to work the airpump, etc. The two pistons of each pair of cylinders as-cend and descend not quite together, one being a little inadvance of the other. Consequently there is no deadcenter for either crank. The sequence of the cylinders will be seen from theplan, fig. 3. Steam is admitted to the high-pressure cylin-der by means of the piston-valve placed between the firsttwo cylinders. The steam passes first into the space be-tween the flanges of the valve, and not into the steam-chest. From thence it is admitted to the cylinder throughthe center cylinder port, and, having done its work, ex-
