Not an Uncommon Case.--Prof. Lusk, of Bellevue Hospital College, New York, related to his medical class in our hearing a case which came under his observation in which all of the children in a large family had been taught the habit by a wicked nurse for the purpose of keeping them quiet after they were put to bed. The vileness that would lead a person to thus rob childhood of its innocence, and blast its prospects for this life and the next, is base enough for the commission of almost any crime. Indeed, the crime could hardly have been a worse one had the nurse referred to in the above case in cold blood cut the throats of those innocent children; perhaps it might have been better for the children. A gentleman once declared that if he should detect a person teaching this crime to his child he would shoot him on the spot; and if homicide is allowable under any circumstances, it seems to us it would be extenuated by such an aggravation. If occasional bad associations will work an immense damage to the youthful character, what terrible injury may be wrought by an agent of sin, an instructor in vice, who is within the household, who presides in the nursery, and exerts a constant influence! No one can estimate it. Acton remarks on this point, "I need hardly point out how very dangerous this is. There seems hardly any limit to the age at which a young child can be initiated into these abominations, or to the depth of degradation to which it may fall under such hideous teaching. Books treating of this subject are unfortunately too full of accounts of the habits of such children." In not a few instances the "hired man" has been the means of communicating to innocent little boys the infamous knowledge which, fortunately, they had not acquired in babyhood. With no knowledge of the evil they are committing, they begin the work of physical damnation which makes a hell of life and leads to endless death. The "hired girl" is often an equally efficient agent for evil in the instruction of little girls in this debasing vice. Some time ago, the very intelligent parents of a bright family of children were awakened to the importance of this subject from the perusal of the first edition of this work, and upon investigation were horrified to find that their oldest child a promising daughter of ten, was already a victim to the vile practice, having been initiated by a "hired girl." After using in vain every means he could bring to bear upon the case, the father brought her to us, and with tears in his eyes gave his story. After telling of his unsuccessful attempts to effect a reform, he declared that he would far prefer to place his daughter in the grave than to see her grow up a wretched victim of this vice. We were most happy to be able, after a few weeks' treatment, to restore her to her parents, as we hope, permanently reformed. Not a few such cases are constantly coming to the attention of the medical profession.
