of malarial poison infested the shores of Greece20 and Asia Minor 2,500 years ago. Nothing is more improbable than that they were always afflicted by the same forms with which we are familiar, or that malaria in any form was constant in any one locality, or that the malignity of the type was such as now fills the army hospitals at Salonica, but the evidence is indubitable that in the Greece of Hippocrates, in some of the islands of the Ægean and on the littoral of Asia Minor-perhaps sometimes in one place, sometimes in another, varying from generation to generation, certainly from season to season-malaria was behind much of the confused picture of disease we find in the Hippocratic writings.

I see no evidence that such affections have ever permanently affected the course of empire, though it is always impossible to say what might have been the course of events if anyone of the innumerable cosmic factors which have shaped history in the abyss of time had been absent. We may be disposed to deprecate the importance of the factor of malaria, but it is impossible to ignore the fact that disease has often in specific instances halted the march of armies on the road to conquest and raised the siege of cities. It is not impossible that in the past, as at present, in some of the districts of central Africa, and in some of the medieval cities, epidemics may have desolated lands and somewhat altered

permanently the course of human events; but for the most part the evidence in regard to the permanent influence of disease on empires and civilizations is dubious. Yet Hippocrates was dealing with this very problem when he noted the effect which airs, waters and localities had on the nature of man. The factors of this problem are not entirely clear in the light modern science has thrown on them, but they are dark indeed, and but a tangled skein of thread,

as we gaze on them in the writings of Hippocrates, through the dimness of more than two thousand years. In the “Epidemics,” we perceive easily, after reading Littré's masterly analysis of the first and third books, that the severest types of malarial fever prevailed on the mainland and the islands which fringed the shores of Greece and Asia Minor in the days of Hippocrates. We take note of the fact that he confused to some extent, as do modern biologists and ethnologists, the effect of “institutions” on men, and the effects of the malarial poison working through the lassitude of their bodies on their moral natures.

Many critics have noticed in Hippocrates the absence of any indication which they can plainly recognize of his appreciation of the infective nature of fevers arising from proximity to the stagnant waters of many of the Greek rivers and swamps. I think this can hardly be laid at the door of antiquity with justice since even in Hippocrates we find reference to the influence of locality on the type of disease in such connection that it can scarcely be doubted that he was familiar with pestilential varieties of swamp fever even if he did miss the plasmodium malariae and took no note of the anopbeles fasciata. In this book we should not fail to notice in this connection his remark that:

Such cities as lie well to the sun and winds, and use good waters, feel these changes less, but such as use marshy and pooly waters, and lie well both as regards the winds and the sun, these all feel them more. And if the summer be dry, those diseases soon cease, but if rainy, they are protracted.

It is interesting in this connection to read what Diogenes Laertius says of the wonders wrought by Empedocles. I give it as translated by Yonge. 21 | 21 Diogenes Laertius, “Lives and Opinions of Eminent Philosophers,” tr. by C. D. Yonge, London: Henry G. Bohn, 1853.

the causes of which were to him unfathomable and mysterious, man sought the help of his gods and naturally applied to those who knew the wishes of the gods, the priests. These tried to appease the wrathful deity with prayers and incantations—a survival of which we see to-day in public prayers for the sick. The priests were always the ablest and shrewdest men in the community and by experience through the ages gained considerable practical knowledge in the treatment of disease. In that way there came to be added to the religious ceremonies methods of therapy of more or less value. The religious practices and therapeutic methods were handed down in the priestly castes by oral tradition.

Among the Greeks, however, the priesthood never had a very strong influence; and the practice of medicine was rather a secret in certain families or social groups. The

. first teacher of medicine among the Greeks was the legendary Esculapius, who taught his son Machaon to bind up the wounds of the Trojan warriors, and his other son, Podalirius, to attend to their internal ills.

Eventually the common experience of the medical families was written down; and a study of the written works was added to oral tradition. The actual teaching was carried out in the so-called iatria, which may be compared to our out-patient departments or dispensaries, and which were usually built in close proximity to an Esculapian temple. In the iatria, the physician received and examined the patients, prescribed and distributed medicines, performed surgical operations and gave instruction to pupils. The most famous iatria or schools, were those of Cnidos and of Cos. The latter was the birth place of Hippocrates, under whom, at about 400 B.C., Greek medicine reached its zenith. As teachers of medicine Hippocrates and his contemporaries, for the most part unknown to us, were not excelled for a thousand years; indeed, for nearly two thousand.

Hippocrates was a wonderful observer

and impressed upon his disciples the importance of bedside observation. In a sense, physical diagnosis originated with him; for he discovered the succussion splash, pleural friction and pulmonary râles. He advised that in order to hear these sounds the ear be laid upon the chest for a considerable length of time. This is the earliest mention of auscultation. The Hippocratic School also tested the temperature of the body with the hand, and by palpation determined the boundaries of the liver and spleen. It is scarcely believable, and yet it is a fact, that fifteen hundred years later these simple but valuable physical methods were thought to be of no importance and were scarcely taught anywhere.

After Alexander the Great's time, Alexandria became the center of Greek life and medical teaching. Under Herophilus and Erasistratus, the Alexandrian School attained great fame, so that it was a distinction to any physician to be able to say that he had studied at Alexandria.

Among the Egyptians, from whom the Greeks undoubtedly derived some of their knowledge, medicine was in the hands of the priests, who controlled all the learned occupations. The foundations of instruction were the Holy Books in which all Egyptian knowledge was contained. These books were an encyclopedic work of forty-two parts, of which the last six were devoted to medicine. The first of these treated of anatomy; the second, of diseases; the third, of surgery; the fourth, of drugs; the fifth, of diseases of the eye; and the sixth, of diseases of women. Only fragments have come down to us. They are contained in the “Book of the Dead,” and in the "Ebers Papyrus.” There are medical allusions in the cuneiform inscriptions of the Babylonians and the Assyrians; but in so far as they have been deciphered, they tell us little about the teaching of medicine, and are chiefly formulas or, as in the Code of Hammurabi, tables of fees and penalties.

Among the Hindoos, the teaching of
