Chemistry : general, medical, and pharmaceutical including the chemistry of the ; a manual on the general principles of the science, and their applications in medicine and pharmacy . ted by evaporation from the unnecessarily largesurface exposed. Washing bottle.—Precipitates are best washed by a fine jet ofwater directed on to the different parts of the filter. A commonnarrow-necked bottle of about half-pint capacity (Fig. 23) is fittedwith a cork ; two holes are bored through the cork, the one for aglass tube reaching to the bottom of the bottle within, and exter-nally bent to a slightly acute angle, the other for a tube bent to aslightly obtuse angle, the inner arm terminating just within thebottle. The outer arms may be about 3 inches in length. The ex-tremity of the outer arm continuous with the long tube should bepreviously drawn out to a fine capillary opening by holding the CALCIUM 109 original tube, before cutting, in a flame, and, when soft, slowly pull-ing the halves away from each other until the heated portion is re-duced to the thinness of a knitting-needle. The tube is now cut atthe thin part by a file, and the sharp edges rounded off by placing in. Fig. 24.
