ALCOHOL. —Laugiek’s Rum Still.

A side view of the apparatus, as it appears set inbrickwork, is seen in Fig. 47 ; A and C are sectionalviews of the boilers heated by the fire, c, under A,round which the flue passes; thence in the directionof the arrows round the second boiler, c, in a similarway, and afterwards into the chimney; G is the rec-tifying- cylindrical vessel, and E the refrigeratorwhere the spirit is condensed. The boiler, A, isfurnished with two pipes; one of these is for dis-charging the contents when all the alcohol is expelled,and is furnished with a stopcock, /; the other pipe,i i i, carries off the generated vapour to the nextboiler, c, where it terminates in a perforated rose,within a short distance of the bottom of the vessel.

Fig. 47.

A pipe issuing from the bottom of C, and fur-nished with a stopcock, j, enters the first boiler andterminates, like the pipe, i, in a perforated rose, asseen at /,'. From C, the pipes, m, n, and /, rise; mand n are connected with the rectifying apparatus inthe cylindrical vessel, G; the former carries off thevapours generated in C, and the latter returns theliquid condensed in this vessel into the boiler.The pipe, l, serves to charge the boiler, C, from therectifying apparatus. Two pipes, o o and I., unitethe rectifier and the condenser; the former conductsthe uncondensed vapours from the rectifier to theworm in the refrigerator, and the latter serves toreplenish the vessel, G, with liquor from the re-

frigorator. The pipe, l, descends to within a shortdistance of the bottom of G, so as to have the colderliquid issuing in contact with the pipes which con-tain the warmer vapours. Another pipe,y>, emergingfrom the cover of the rectifying vessel, conductsany vapour generated by the condensation in partof the distilled products of the boilers, A and c, tothe condenser. The refrigerator is filled throughthe funnel tube, t, from the tank, v, by means ofthe pipe and stopcock, u.

The manner of working the still is simple :—Liquor is allowed to enter the funnel tube, t, untilit begins to flow down the pipe, l l , into the boiler,c; and as soon as this is observed the stopcock, j,

is opened, and the liquor admitted into the firslboiler until it rises a few inches above the rose, A:,as shown by the glass gauge, g g ; the stopcock,/, is shut, and the liquor allowed to flow into cuntil it rises above the end of the pipe, 11, whichemerges into the liquor; this is shown by anothergauge pipe, (f g', attached to c. The stopcock, u,is now closed, and the fire urged under the firstboiler, the contents of which very soon boil,and are partly converted into vapour, which isemitted to the next boiler through the pipe, i i. Bymeans of the heat abstracted from the vapour inpassing through the liquid, and that communicatedto the boiler by the flue which circulates round c,
