The lower end of the cylinder is closed with a rubber stopper bearing the small arm of the siphon {o). The tube furnishing the water sup- ply is connected with a reservoir provided with a constant-level attach- ment. To the lower end of the small arm of the siphon is attached a glass tube (wi) bearing a small bulb which materially assists in break- ing the flow of the water at the moment the aspirator is emptied. The tubing connecting the parts of the apparatus should not be less than 100âIV.
