An increased secretion of saliva marks the first advance of the teeth, followed, in irritable habits, by diarrhea, fever, thirst, and convulsions. The use of the gum-lancet should not be neglected, whenever the symptoms are urgent. The parents frequently object to this mode of relief, conceiving it to be a painful operation. As a proof of the contrary, children that have once been relieved by it, will eagerly press their gums upon the lancet. If the tooth should not appear after the first use of the lancet, the incision may be frequently repeated. The symptoms may be relieved by the following emetic:--Take of tartar-emetic, one grain; dissolve it in two ounces of distilled water. Dose, two tea-spoonfuls every half-hour, until it excites vomiting. This remedy will relax the tension of the gums, and lessen the force of the fever. If the habit of the child should be costive, the mildest purgatives should be employed, to occasion two or more motions daily--such as manna, dissolved in common mint-water; or senna-tea; or the following:--Take of senna leaves, one drachm; the yellow rind of the lemon, eight grains: boil them in two ounces of water; strain off the liquor, when cold; and give a dessert-spoonful as a dose for children three or four months old. Or, take manna and fresh-drawn oil of sweet almonds, of each, one ounce; syrup of roses, two ounces: mix them together. Dose, a dessert-spoonful. 853. _The Croup_--At its commencement has the appearance of common catarrh, but speedily assumes its peculiar character, which is marked by hoarseness, with a shrillness and ringing sound in coughing and breathing; so shrill is the noise made by the child, that it resembles the sound of air forced through a tube of brass. This inflammation, seated in the membrane which lines the windpipe, is attended with stricture, difficult respiration, cough, quick pulse, heat, and a flushed countenance. This disease comes on suddenly, and is extremely rapid in its progress; therefore, vigorous measures must be instantly adopted. Give an emetic, then apply a blister across the throat, and keep the bowels open with laxative injections. 854. _Cure for Croup._--Dr. Fisher, of Boston, relates in a late number of the Medical _Journal_, a case in which a severe attack of croup was cured by the application of sponge, wrung out of hot water, to the throat, together with water treatment, which he describes as follows:-- "Soon after making the first application of sponges to the throat, I wrapped the child in a woolen blanket, wrung out in warm water, as a substitute for a warm bath, and gave twenty drops of the wine of antimony in a little sweetened water, which was swallowed with difficulty. I persevered in the application of the hot, moist sponges for an hour, when the child was so much relieved that I ventured to leave it. "These applications were continued through the night, and in the morning the child was well."
