The first thing, of course, to be done, is to send _immediately_ for a medical man. Have a plentiful supply of cold and of hot water always at hand, ready at a moment's notice for use. The instant the paroxysm is upon the child, plentifully and perseveringly dash _cold_ water upon his head and face. Put his foot and legs in _hot_ salt, mustard, and water; and, if necessary, place him up to his neck in a hot bath, still dashing water upon his face and head. If he does not quickly come round, sharply smack his back and buttocks. In every severe paroxysm of child-crowing, put your fore-finger down the throat of the child, and pull his tongue forward. This plan of pulling the tongue forward opens the epiglottis (the lid of the glottis), and thus admits air (which is so sorely needed) into the glottis and into the lungs, and thus staves off impending suffocation. If this plan were generally known and adopted, many precious lives might be saved. [Footnote: An intelligent correspondent first drew my attention to the efficacy of pulling forward the tongue in every severe paroxysm of child-crowing.] There is nothing more frightfully agonising to a mother's feelings than to see her child strangled,--as it were,--before her eyes, by a paroxysm of child crowing. As soon as a medical man arrives, he will lose no time in thoroughly lancing the gums, and in applying other appropriate remedies. Great care and attention ought, during the intervals, to be paid to his diet. If the child be breathing a smoky, close atmosphere, he should be immediately removed to a pure one. In this disease, indeed, there is no remedy equal to a change of air--to a dry, bracing neighbourhood. Change of air, even if it be winter, is the best remedy, either to the coast or to a healthy mountainous district. I am indebted to Mr Roberton of Manchester (who has paid great attention to this disease, and who has written a valuable essay on the subject [Footnote: See the end of the volume of "Physiology and Diseases of Women," &c. Churchill, 1851.]) for the knowledge of this fact. Where, in a case of this kind, it is not practicable to send a child _from_ home, then let him be sent out of doors the greater part of every day; let him, in point of fact, almost live in the open air. I am quite sure, from an extensive experience, that in this disease, fresh air, and plenty of it, is the best and principal remedy. Cold sponging of the body too is useful.
