On the otherhand, it is soluble in chloroform, and when the syringesmade of it require repairs they can be made only at theshops of the celluloid company. Hard rubber is a suitablematerial for syringes, but they are usually made verypoorly. An exception to this statement is the syringe of 36 HYPODERMATIC MEDICATION.

Of course the contents of a hard-rubber syringe are not visible, but the graduation of thepiston may be accurate. Fig. Fig. 6.
