However, inasmuch as the authority with which the society sought to be invested had reference to public justice, and involved the power to appear for the defence of the interests of others, and to require the cooeperation of public officials, a law was indispensable, in order to confer these powers. Such a law was passed August 21, 1875, whose provisions covered not only the case of the New York society, but determined the functions of all institutions of a similar nature.

Experience showed that, besides the misdemeanors of common law—attempts upon the morals, murder, assault and battery, etc.—a multitude of offences against children remained unpunished.
