Alcohol, coffee, and tea are especially injurious to children. The celebrated German clinician, Strümpell, writes as follows in the _Pædagogical Pathology_: “Among the acute as well as chronic intoxications—which can be the cause not only of a temporary, but also of a prolonged psychopathic condition,—intoxication by alcohol, and by stimulants generally, plays the greatest rôle. Such abuse is especially noxious to children, and causes an enormous number of diseases with psychopathic results.” We ourselves believe that it is a crime to give alcohol to children, and that it should be punishable as such. Dr. F. Heyn, in a statistical contribution on “Idiocy,” that appeared recently in the _Psychiatrisch Neurologische Wochenschrift_, showed that in 17.6 per cent. of cases of idiocy in children the above-mentioned fault in hygiene—the use of alcohol, tea, and coffee—was the cause. Thirteen years ago Director Trüper, in a monograph on the psychopathic conditions of childhood, insisted on abstinence not only from alcohol, but also from coffee, by women during pregnancy; but it should be noted also that these agencies continue to be deleterious years after a child is born. Above all else we must try to make a good man or woman of the child, as this also is an essential safeguard against disease and premature old age. We should endeavor to interest children while they are yet of a school age in the fine arts, such as music, painting, and literature, as they have a very favorable influence on the hygiene of the mind in after years. Religious instruction also gives good results in this respect. When children approach puberty it is important to avoid an agency that may prove very deleterious to certain of the glands with internal secretions, and this is masturbation. We will not commit the error made by so many unscientific writers of ascribing much greater importance to this matter than it deserves. It certainly is not true that tabes dorsalis, dementia paralytica, or other serious nervous diseases will result from this source; but it cannot be denied that neurasthenia or hysteria or impotency—sexual neurasthenia—can be promoted by the exaggeration of masturbation, if indulged in many years. Masturbation is always injurious to the sexual glands, more so to the male than to the female organs, and in addition to the thyroid, and—if in excess—to the adrenals. It also very unfavorably influences the mind and character. In youth, instruction as to the control of the sexual passions will be of the utmost importance, even considering alone the dangers of infections, especially of gonorrhœa, which not only endangers the future husband, but the future wife also. We need here but mention the well-known fact that the thorough and radical cure of syphilis may even more readily be accomplished than that of chronic gonorrhœa.
