Per m. / 5 revolutions =386 pounds water capacity for all of the buckets on the wheel. If such a wheel is constructed with 16 blades and 16 buckets, onebetween each blade, then 386 / 16 = 24 pounds for each bucket, or 38 /100 of a cubic foot. The spill from this capacity of bucket being sufficient to compensatefor the friction of the shaft journals. The lifting buckets of the noria class, Figs. 26 and 27, can be made ofpositive dimensions to suit the computations as above; but those of thetympa...num class, Fig. 25, should be made of dimensions to conform withthe required capacity at the moment of leaving the water, as the waterat this point flows into the arm. (_To be continued_. ) * * * * * To remove paint and varnishes, which resist the action of strong lye, Dr. Stockmeier recommends a mixture of water of ammonia, two parts, andturpentine, one part; this applied to the surface to be cleaned will, after a few minutes' action, enable the paint to be removed by use ofcotton waste or similar material.
