A test of a 10-in. engine running 600 revolutions permin. gave a water consumption of 37 lbs. per brake horse-power per hour. Compound Steam Turbine.—Mr. Charles A. Parsons describes, in the Proc. Inst. 31. E.,October, 1888, a compound steam turbine of his invention, as follows : The compound steamturbine 7(Figs. 10 and 11) consists of two series of parallel-flow or Jonval turbines, set one 298 EXGIXES, STEAM NOTARY, after the other on tlie same spindle S, so that each turbine takes steam from the one beforeand passes it on to the one following:. In this way the steam entering all round the spindle.
