When this is lacking, a tube, tenmillim. wide, drawn out to a point at one end, can be used. Finally, a small wash bottle, Fig. 68, or a dropfing glass, Fig. 69,is necessary. By blowing air into the tube, a, Fig. 68, which opensclose under the cork, a steady stream of water is forced out throughh. A glass flask of about forty-five millim. diameter is quite largeenough. On inclining the spout of the half-filled dropping glass,Fig. 69, so far that the water runs into it, a few drops will fomo. 44 PLAITlfEES BLOWPIPE ANALYSIS.
