The habit of sucking the thumb may be corrected by wearing a pair of white mittens, or gloves tied at the wrist. Should children attempt to suck the thumb with gloves on, as some do, it will be necessary to saturate the thumb and fingers of the gloves with tincture of aloes, or a solution of the bisulphate of quinine, one dram to two ounces of water. BITING THE FINGER NAILS Biting the finger nails may be stopped by the use of the same bitter remedies as are used in thumb-sucking. HOW TO WASH OUT THE BOWELS COLON IRRIGATION. A HIGH ENEMA Procure a soft rubber catheter,--No. 18 American is about right. It is not advisable to get too soft rubber for the reason that it will buckle when the child strains and it will be impossible to wash out the bowel. Fill half full an ordinary two-quart douche bag with water that is warm, but not too hot. Dissolve a heaping teaspoonful of table salt in a glass of hot water and add this to the water in the bag. Hang the bag about two feet above the level of the child, so that the water will not flow in with too strong a stream; otherwise the child will immediately try to eject it. If the water flows in gently, the child may not object to it to the extent of making strenuous efforts to force the catheter out. Use the small sized nozzle that comes with the douche bag. Place the rubber catheter over this nozzle, lubricate the catheter, place the child on its back over a douche pan, insert the catheter about two inches, let the water run and as it runs in push the catheter up gently until it is all in the bowel except the end on the douche tip. The object of letting the water run while pushing in the catheter is because it floats up with the water as it distends the bowel; there is no risk then of pushing the end into the intestinal wall or hurting the child. While the water is flowing into the bowel it is a good plan to compress the buttocks together to aid in holding the water, as the child is very apt to let it run out as soon as it feels uncomfortable. The temperature of the water for the ordinary rectal injection should be 95 deg. F. When the child is exhausted or very weak, or when the circulation is poor, the temperature of the water may be as high as 110 deg. F. When, on the other hand, the fever is very high, the water may be much cooler; as low as 70 deg. F. has been given with good results on the fever. If the irrigation is given with the intention of reducing the fever, it is best to begin with water around 90 deg. F., and reduce it to 70 deg. F., gradually. Indications for Irrigation of the Colon.--When it is desired to cleanse the bowel of any collection of matter a colon irrigation is indicated. This matter may be mucus, fecal substance, undigested food, or the decomposing waste products which may remain there as a result of disease or other conditions. When it is desired to medicate by putting fluids into the bowel we adopt the colon infusion.
