The act of introducing, by means of a syringe or other instrument, a liquid into a cavity of the body. The liquid injected is also called an injection. Anatomists use injections for filling the cavities of vessels, in order that they may be rendered more apparent, and their dissection be facilitated. For this purpose, they employ syringes of different dimensions, and various materials. The most common injections are made of soot, wax, and turpentine, coloured with lamp-black, vermillion, etc. There are three kinds chiefly used by anatomists, - the coarse, the fine, and the minute. In order to inject the arteries, the injection must be forced from the great trunks towards their ultimate ramifications. To inject the veins, on the contrary, it is indispensable, on account of their valves, to send the injection from the smaller divisions towards the greater. The lymphatics are usually injected with mercury. The practitioner injects, by forcing with a syringe, liquids, such as emollient, narcotic, stimulant, and other decoctions or infusions, into different hollow organs, as the rectum, vagina, nasal fossas, urethra, tunica vaginalis, auditory canal, etc., to fulfil various therapeutical indications. The saline constituents to be dissolved first of all in boiling hot water; the molasses to be afterwards stirred in; the starch to be mixed well with half a pint of cold water, and then to be stirred in with the other articles. As soon as it begins to boil, the whole mass swells up, when it must be removed from the fire. On the proper reduction of temperature it is fit for use.
