Stimulants, throughout the whole period of infancy and childhood, and of every description, must be prohibited. Children nursed by drunken parents, and who have indulged in the use of spirituous liquors during suckling, are never healthy; are the frequent subjects of convulsions, and many of them die eventually of water in the head. The practice of administering spirits to the child itself; a habit unfortunately not very uncommon among the lower classes; produces a similar result. Narcotics may operate in a like manner: they derange the whole system when persevered in, particularly affecting the brain; promote disease; and sometimes give rise to the one in question. This remark should be borne in mind by the mother, as Godfrey's Cordial and other preparations of opium are too often kept in the nursery, and secretly given by unprincipled nurses to quiet a restless and sick child. All causes of mental excitement should be carefully avoided, and particularly the too early or excessive exercise of the intellectual faculties. If the child be endowed with a precocious intellect, the parent must restrain rather than encourage its exercise. Nothing is more likely to light up this disease in a constitution predisposed to it, than a premature exertion of the brain itself. MATERNAL MANAGEMENT OF THE DISEASE.--The early detection of this disease is of great importance. The chances that the medical treatment will terminate successfully much depend upon the early and prompt application of remedial means. The reason why these cases have so often terminated fatally has arisen from the physician being consulted when irremediable mischief had already taken place. It would be difficult, however, to point out the signs of its approach in all its forms (for this disease does not always commence in the same way, sometimes with fever, etc.), still it most frequently occurs preceded by certain striking and well-marked symptoms; and whenever the following are noticed by the parent apprehensive of mischief, she should at once send for her medical adviser:--watchfulness, or starting from sleep with a cry of alarm; prolonged screaming without any obvious cause; moaning and drowsiness; rolling the head from side to side on the nurse's arm, or thrusting it back against the pillow; knitting the brows and aversion from light, with heat of head, and constant carrying the little hand up to it; half closing the eyelids, and frequent vomiting.
