If solutions be kept, as- suming them to be salts of alkaloids, they must be charged with some preservative, such as hy- drate of chloral, carbolic acid, salicylic acid, etc. One per cent, addition of any of these bodies proves antiseptic, but the same are all more or less irri- tant, and hence fresh solutions are preferable. For convenience in making fresh solutions, manu- facturers offer tablets charged with fixed quanti- ties of the things commonly used for hypodermatic injection. These tablets are simply dissolved in a few drops of water on the occasion of the injecting. Such tablets are made of gelatin or of sodium sul- phate, the salt in the latter instance being given form and cohesion by powerful pressure. These medicated tablets, if of reliable make, are ex- ceedingly convenient, the compressed tablets of the sodic salt especially so, provided they are fresh enough to dissolve readily. Being ready with a good syringe and a good solution, we fill the one with a sufficiency of the other, then hold the syringe vertical, needle-end up, and gently push upon the piston until fluid appears at the needle orifice. Thus the bubble of air, which it is practically impossible to prevent from having place within the cylinder, is dis- charged, and we are now certain that the syringe is just as full of solution as it purports to be.
