In five to ten grain doses it helps to stop diarrhœa, bleeding from stomach, bowel, piles, and bladder. If there is continued bleeding, increase the dose to twenty grains, and repeat it as often as necessary. _Voice tablets_, consisting of chlorate of potash, borax and cocaine are useful in cases of sore throat. _Warburg’s tincture._—One tablet is equal to thirty drops of the ordinary tincture. Stronger tablets are also available. To produce sweating, first open the bowels, then give four to eight of the tablets with a little hot spirit and water. If necessary, repeat the dose in three hours, and in either case withhold if possible food or drink till after this period has elapsed, but if the patient is very thirsty give hot drinks of weak tea or spirit and water. Keep him covered up and put a hot-water bottle in the bed. Urgency of the case is a guide as to how many tablets ought to be given. _Zinc oxide_ alone or mixed with an equal quantity of boric acid or starch makes a useful drying dusting powder. _Zinc ointment_ contains three parts of zinc oxide to seventeen parts of lard or vaseline. This is a most useful application for burns, eczema, chafes and sores. _Sulphate of zinc._—As a prompt emetic, give twenty to thirty grains in half a pint of warm water. If patient does not vomit give a pint or more of warm water and tickle the back of the throat. A second dose of the drug may be given. Two grains to an ounce of water makes a valuable astringent lotion for gonorrhœa, raw surfaces, ulcers, and inflamed eyes and ears. The strength of this solution may be gradually increased to six grains to the ounce of water. TEMPERATURE TAKING, HYPODERMIC INJECTION, BATHS, CATHETERS, STOMACH TUBES, ENEMAS, AND POULTICES. _Pulse, Respiration and Temperature._ Normal pulse rate (adult) about 72 per minute. Normal respiration rate (adult), 15 to 18 per minute. Normal temperature, 98.4° F., but varying in health between 97.5° and 99°. _Temperature Taking._ The temperature of the body may be taken in the armpit, the mouth, or the lower part of the bowel. _In the Armpit._—Dry armpit well, put the bulb of the thermometer into it, and press the arm tightly against the body, so that the thermometer will be in close contact with the skin on either side for at least five minutes. _In the Mouth._—Wash the thermometer in an antiseptic solution, dry it and place the bulb well under the tongue and close the lips on the stem; at least three minutes should be allowed. This is a more reliable way of taking the temperature than in the armpit.
