evidently taken from the author's other works, especially those "On Air," etc., "On Prognostics," and "On the Articulations." They embody the result of a vast amount of observation and reflection, and the majority of them have been confirmed by the experience of two thousand years. A proof of the high esteem in which they have always been held is furnished by the fact that they have been translated into all the languages of the civilized world; among others, into Hebrew, Arabic, Latin, English, Dutch, Italian, German, and French. The following are a few examples of these aphorisms:

"Spontaneous lassitude indicates disease."

"Old people on the whole have fewer complaints than the young; but those chronic diseases which do befall them generally never leave them."

"Persons who have sudden and violent attacks of fainting without any obvious cause die suddenly."

"Of the constitutions of the year, the dry upon the whole are more healthy than the rainy, and attended with less mortality."

"Phthisis most commonly occurs between the ages of eighteen and thirty-five years."

"If one give to a person in fever the same food which is given to a person in good health, what is strength to the one is disease to the other."

"Such food as is most grateful, though not so whole

some, is to be preferred to that which is better, but distasteful."

"Life is short and the art long; the opportunity fleeting; experience fallacious and judgment difficult. The physician must not only do his duty himself, but must also make the patient, the attendants and the externals, co-operate."

Hippocrates appears to have travelled a great deal, and to have practised his art in many places far distant from his native island. A few traditions of what he did during his long life remain, but differences of opinion exist as to the truth of these stories.

Thus one story says that when Perdiccas, the King of Macedonia, was supposed to be dying of consumption, Hippocrates discovered the disorder to be lovesickness, and speedily effected a cure. The details of this story scarcely seem to be worthy of credence, more especially as similar legends have been told of entirely different persons belonging to widely different times. There are, however, some reasons for believing that Hippocrates visited the Macedonian court in the exercise of his professional duties, for he mentions in the course of his writings, among places which he had visited, several which were situated in Macedonia; and, further, his son Thessalus appears to have afterwards been court physician to Archelaus, King of Macedonia.

Another story connects the name of Hippocrates with

the Great Plague which occurred at Athens in the time of the Peloponnesian war. It is said that Hippocrates advised the lighting of great fires with wood of some aromatic kind, probably some species of pine. These, being kindled all about the city, stayed the progress of the pestilence. Others besides Hippocrates are, however, famous for having successfully adopted this practice.

A third legend states that the King of Persia, pursuing the plan (which in the two celebrated instances of Themistocles and Pausanias had proved successful) of attracting to his side the most distinguished persons in Greece, wrote to Hippocrates asking him to pay a visit to his court, and that Hippocrates refused to go. Although the story is discarded by many scholars, it is worthy of note that Ctesias, a kinsman and contemporary of Hippocrates, is mentioned by Xenophon in the "Anabasis" as being in the service of the King of Persia. And, with regard to the refusal of the venerable physician to comply with the king's request, one cannot lose sight of the fact that such refusal was the only course consistent with the opinions he professed of a monarchical form of government.

After his various travels Hippocrates, as seems to be pretty generally admitted, spent the latter portion of his life in Thessaly, and died at Larissa at a very advanced age. It is difficult to speak of the skill and painstaking perseverance of Hippocrates in terms which shall not

appear exaggerated and extravagant. His method of cultivating medicine was in the true spirit of the inductive philosophy. His descriptions were all derived from careful observation of its phenomena, and, as a result, the greater number of his deductions have stood unscathed the test of twenty centuries.

Still more difficult is it to speak with moderation of the candour which impelled Hippocrates to confess errors into which in his earlier practice he had fallen; or of that freedom from superstition which entitled him to be spoken of as a man who knew not how to deceive or be deceived ("qui tam fallere quam falli nescit "); or, lastly, of that purity of character and true. nobility of soul which are brought so distinctly to light in the words of the oath translated below :—

;

"I swear by Apollo the Physician and Æsculapius, and I call Hygeia and Panacea and all the gods and goddesses to witness, that to the best of my power and judgment I will keep this oath and this contract; to wit -to hold him, who taught me this Art, equally dear to me as my parents; to share my substance with him to supply him if he is in need of the necessaries of life; to regard his offspring in the same light as my own. brothers, and to teach them this Art, if they shall desire to learn it, without fee or contract; to impart the precepts, the oral teaching, and all the rest of the instruction to my own sons, and to the sons of my teacher,

and to pupils who have been bound to me by contract, and who have been sworn according to the law of medicine.

"I will adopt that system of regimen which, according to my ability and judgment, I consider for the benefit of my patients, and will protect them from everything noxious and injurious. I will give no deadly medicine to any one, even if asked, nor will I give any such counsel, and similarly I will not give to a woman the means of procuring an abortion. With purity and with holiness I will pass my life and practise my art. Into whatever houses I enter I will go into them for the benefit of the sick, keeping myself aloof from every voluntary act of injustice and corruption and lust. Whatever in the course of my professional practice, or outside of it, I see or hear which ought not to be spread abroad, I will not divulge, as reckoning that all such should be kept secret. If I continue to observe this oath and to keep it inviolate, may it be mine to enjoy life and the practice of the Art respected among all men for ever. But should I violate this oath and forswear myself, may the reverse be my lot."
