Injections of the urethra are made with syringes to containabout an ounce of liquid, (Fig. 140 ;) the syphon portion isintroduced completely into the canal, which latter is heldso that it closely embraces the instrument, while withthe other hand the piston is forced upon the liquid, (Fi§.140.) It is important that the finger making the com-pression should not go beyond the point of the syringe, andthat the injection thus forced in should be retained a minute ortwo in its place, or, if it is not of a very active nature, that it be (Fig. 140.). repeated two or three times at each sitting.
