Modifications of an Aseptic easily 
Sterilisable Glass Syringe.* — Dr. S.

syringe. This syringe consists of a 
graduated glass tube, pointed at one 
end for the cannula, and a glass piston-

Another modification is shown in fig. 61. As will be seen by 
comparing the two illustrations, the second modification consists in an
