The tales of lycanthropy which are found in such different ages and remote countries, strongly supported the Doctor's theory. Virgil, and Ovid in his story of Lycaon, had only adapted a popular superstition to their purposes. And like its relator he regarded as a mere fable the legend which Pliny has preserved from the lost works of Evanthes a Greek author not to be despised. Evanthes had found it written among the Arcadians that a man from the family of a certain author in that country was chosen by lot and taken to a certain lake; there he stript, hung his garments upon an oak, swam across and going into the wilderness, became a wolf, and herded with wolves for nine years; and if during that time he abstained from doing any hurt to men, he returned to the lake, recrossed it, resumed his human form, with the only change of being the worse, not for the wear indeed, but for the lapse of those nine years; and moreover found his clothes where he had left them. Upon which Pliny observes, _Mirum est quo procedat Græca credulitas! Nullum tam impudens mendacium est quod teste careat._ A worse manner of effecting the same metamorphosis Pliny relates from the Olympionics of Agriopas; that at a human sacrifice offered by the Arcadians to Jupiter Lycæus, one Demænetus Parrhasius tasted the entrails, and was transformed into a wolf; at the expiration of ten years he resumed his original form, and obtained the prize of pugilism at the Olympic games. But the Doctor differed from Pliny's opinion that all which is related concerning lycanthropy must be rejected or all believed;—_Homines in lupos verti rursumque restitui sibi, falsum esse confidenter existimare debemus; aut credere omnia, quæ fabulosa tot seculis comperimus._ The belief however, he admits, was so firmly fixed in the common people that their word for turncoat was derived from it;—_Unde tamen ista vulgo infixa sit fama in tantum, ut in maledictis versipelles habeat, indicabitur._ These fables the Doctor argued, could not invalidate the testimony of ancient physicians, that there was an actual and well known species of madness, in which men howled like wolves, and wandered by night about in lonely places or among the tombs. It was most severe at the commencement of spring; and was sometimes epidemic in certain countries. Pieter Forest whose character for accuracy and sagacity stands high among medical writers, affirms that he, in the sixteenth century, had seen the disease, and that it was as it had been described by the ancients. He must have been a credulous person who believed Constantinople had been so infested by these wolf-men, that the Grand Seignior and his guards had been obliged to go out against them; killing a hundred and fifty, and putting the rest of the pack to flight. This was a traveller's tale; and the stories related in books of demonology and witchcraft, concerning wretches who had been tried and executed for having, in the
