The barrel of the syringe is the large cylindrical part in which the piston fits. The injecting mass is drawn into it by pulling the piston in the direction of the handle. Canuia,. Pig. 85.—White-Metal Syeingb with Top Unsckbwbd and Piston Removed ; x .3. Canuia.—The canuia is the smaller part which serves to connect the syringe with the object to be injected. Handle.—The handle is a continuation of the piston. It projects from the barrel, and by it the piston is moved. Piston.—The piston of a syringe is within the barrel. Its end should be packed with leather, as shown in the figure, so that it will fit very closely. Canuia or Nozzle.—The canuia serves to connect the syringe with the object to be in- jected. The end should be cut oflf obliquely. It is then like a wedge, and may be inserted into the vessel much more easily than one cut squarely oif. The caliber of the canuia should be as \ ^^ P great as can be put into the vessel to be in- " jected. For plaster injections (§ 341) the canuia should not be less than 1 mm. at its narrowest point. A.—Metal canuia with lateral arms at the end next the syringe, and a slight shoulder at the small end. B.—A glass canuia cut ofi'obliquely at its small end. C.—A glass tube drawn out for two canulae. § 340. To prepare glass canulse, take a glass tube about 6 mm. in diameter and from 8-10 cm. in length, and heat its middle evenly in a Bunsen flame. When the glass is softened, draw the two ends apart until the tube is sufficiently reduced in caliber in the middle ; then after cooling make a fine scratch with a file as shown in C, and the two may be broken apart. When separated, grind the end first on a fine file with water to make it oblique as in A and B, and finally on the fine oil stone to make it smooth. Heat the larger end
