A elevation of a kilowatt stcanvkilowatt Curtis steam-turbine connected to a generat large steam-turbines which follow Parsonsvery closely in theory, but are differently workedout mechanically. Few revolving disks of com-paratively large diameter are arranged, and thefixed steam nozzles only play upon part of theirperiphery, in some cases only two nozzles beingemployed on the first disk. Provision is madefor altering the nozzle areas according to loadby opening or closing their tapered walls, thusto a certain extent permitting correct mainte-nance of expansion ratios for varying steampressures and loads. Prof. Curtis argues thatbis arrangement of a few large nozzles andwheels in series lessens the percentage of wastethrough spilling of steam. In order to reducethe revolutions per minute as far as possible,Mr. Parsons appears to advocate a large num-ber of turbines in series of small diameter, while engine direct-connected to a generator, and a 5,00^or, showing econo
