The instrument consists of a flask (A) of any desired capacity, though I have found that one of 500 c.c. is the most suitable for general use, with the highest graduation at the top, provided with a rubber stopper with a single hole (B) through which passes a glass tube (C) so constructed that it at the same time empties the flask and admits the air necessary to empty the flask. Attached to the rubber stopper is a framework (D) of German silver, on which the rubber tubing (E), of sufficient length to allow a good head of pressure, is
