The condenser (figs. 3 and 5. .1) consists of a plain copper tank 4 inches wide. 1-2 inches high, and of the same length as the evaporating chamber {B). In the bottom of the tank at points directly opposite the center of each of the compartments of the evaporating chamber are cut 1-inch holes for receiving the per- forated rubber stoppers (e) thru which the ends of the glass con- denser tubes (s) project into the measuring cylinders (/). Heavy one-eighth inch washers {d) are soldered around the holes in the bottom of the tank, so that the rub- ber stoppers (e) bearing the con- denser tubes (s) can be prest in firmly, thereby avoiding the possible danger of any water leaking from the tank into the measuring cylni- ders. Thru the condenser tank passes a stream of cold water, en- tering thru the valve («) and pass- ing out at the overfloAv pipe (e). Connected Avith the valve («) is a three-eighths inch pipe (7j) . which extends the full length of the tank. In this pipe, near each condenser tube, are two small holes (jy). drilled at such an angle that the cold water entering the tank will fall directly on the glass condenser tubes. In order to prevent the sides of the tank from bulging, extra braces (/) should be put in everv 10 or 18 Fig. 8.—End view of apparatus fur moisture determination.
