There have been, alas! numerous cases of insanity in the reigning house of Prussia. Old Emperor William's elder brother and predecessor, King Frederick-William IV., spent the last few years of his life under restraint, hopelessly insane, his brother and ultimate successor administering the government as regent. The late Princess Frederick of Prussia was afflicted like her brother, the last Duke of Anhalt-Bernburg, with a peculiar kind of lunacy which took the form of an invincible objection to clothing of any kind whatsoever; while one of her two sons, Prince Alexander, who died only a few months ago, suffered from a species of good-natured imbecility, which led him to offer his heart and his hand to every woman or young girl that he encountered, no matter what her age, or looks, or rank, sometimes making as many as thirty or forty offers of marriage in the same day! The above-mentioned law was created for the purpose of preventing a prince thus situated from ascending the throne of Prussia, but the family statutes evoked by Prince Bismarck and his followers certainly never contemplated the deprival of a prince of his hereditary rights of succession to the throne because of some physical ailment or infirmity. This would have been entirely contrary to the spirit and ethics of the monarchical system of the Old World; as will be readily seen when attention is called to the fact that both the late King of Hanover, and the present reigning Grand Duke of Mecklenburg-Strelitz, were absolutely and totally blind at the time they succeeded to their present thrones. Prince Bismarck took the view, however, that the statute in question was sufficient to bar "Unser Fritz" from succeeding to his father, if it were once medically admitted that his malady was incurable, or if curable, that it was liable to permanently destroy the vocal chords, thus abolishing forever the power of speech. Prince Bismarck declared that in a matter of such extreme importance, where the succession to the throne, and the life of the heir apparent were at stake, the surgeons and physicians should be selected by the State--that is, by himself--and that their verdict should be final. Chief among the medical experts whom he nominated for the purpose, was the celebrated German surgeon, Professor von Bergmann, who is as famed for his skill in the use of the knife as for his fondness in applying it in cases where it might possibly be dispensed with. Having convinced himself that the malady from which Crown Prince Frederick suffered was a cancer, he decreed that the only manner of saving the life of the illustrious patient was the extremely dangerous and almost certainly fatal operation of removing the entire portion of the larynx that was affected. This, as stated above, would have left the crown prince dumb for the remainder of his days, and according to the views of Prince Bismarck would have barred him from succession to the throne.
