In the absorption tube it is drawn out and somewhat curved inits course, so that its extremity f is directed towards the centre ofthe absorption tube. The diameter of the orifice of the tube slfis less than i mm. At the enlarged portion of the absorption tubethe small tube a is bent, and terminates nearly opposite and about5 cm. from the stopper. The aspirator bottle B is connected withthe absorption tube A by tubing. The manometer vi communi-cates with the absorption tube and aspirator bottle by means of.
