Slip the end of tubing which isto go into the flask into the carrier at the point whereit will go over the rim of the flask, arranging it so thetip of the glass tube just escapes the bottom of theflask. Do not put the tubing into the flask untilthe doctor is ready to use it; he then generally does sohimself, and starts the liquid flowing, either by ex-. Fig. 87. Continuous Clysis pressing the air by drawing the tubing between hisfingers, or by suction obtained by disconnecting themain tubing from the T, inserting the nozzle of thesyringe in it, and slowly drawing up the piston whenthe flow is started; reconnecting the tubing andallowing the fluid to flow through the needles to expelall air, after which he inserts them in the given in this way it takes about one-half hourfor a liter of solution to enter the tissues. Sometimes a larger quantity of solution is such case, it is given very slowly and means must Aseptic Precautions 573 be taken to keep the solution hot. One of the easiestways of doing this is to support the flask on an ironstand such as is used in any chemical or pathologicallaboratory, and to keep a lighted Bunsen burner underbut at some distance from it. Usually only a verysmall flame is required; a thermometer must be keptin the solution and it must be lo
