On a New Nozzle and Pipe for Injecting Syringes.— Having had 

 many years' experience in the frequent use both of small and 

 large injecting syringes, either for the injection of the whole 

 animal or detached organs, I have frequently felt the gieat 

 inconvenience of the ordinary plan of fixing the syringe on 

 to the injecting pipe, and consequent need of some simple 

 plan for keeping the pipe firmly attached to the syringe while 

 in use. By the present method of fitting the nozzle of the 

 syringe to the pipe it is generally necessary, more particularly 

 when the syringe is large, to keep the left hand constantly on 

 the pipe to prevent its being forced away from the syringe 

 when any amount of pressure is being applied, thus 

 preventing the hand being quite free to lift the specimen 

 from time to time, to see how the injection is going on. 

 When any extravasation takes place, and an assistant is not 

 at hand (the operator wishing to have both hands quite 

 free), it is not safe to lay the syringe with the pipe attached 

 down, but the nozzle has to be detached and a cork placed in 

 the pipe till the extravasating vessels are taken up. It also 

 often happens that Avhen considerable pressure is being applied 

 to the syringe, and the hand is not kept firmly on the pipe, 

 it is violently forced away from the nozzle, and the ope- 

 rator and articles about the room are smothered with injecting 

 fluid. This happens very often with beginners, and is one 

 of their greatest difficulties. I had for many years thought 

 of various plans for fixing the pipe on the syringe, but had 

 never hit on a satisfactory and simple method till I joined 

 the volunteer force, and became acquainted with the method 

 of fixing the bayonet to the long Enfield rifle, when it oc- 

 curred to me that a similar arrangement was just what was 

 required to remedy the evils I have enumerated. 



A small pin is inserted into the nozzle of the syringe, suf- 

 ficiently long to project a little way beyond a corresponding
