the man-midwife, for it was rather unusual for men to have much knowledge of this subject. His knowledge of the phenomena of menstruation was as wide and definite. He knew a great deal of how to treat its disturbances. He seems to have been the first one to suggest that in metrorrhagia, with severe hemorrhage from the uterus, the bleeding might be stopped by putting ligatures around the limbs. This same method has been suggested for severe hemorrhage from the lungs as well as from the uterus in our own time. In hysteria he also suggested ligature of the limbs, and it is easy to understand that this might be a very strongly suggestive treatment for the severer forms of hysteria. It is possible, too, that the modification of the circulation to the nervous system induced by the shutting off of the circulation in large areas of the body might very well have a favorable physical effect in this affection. Paul's description of the use of the speculum is as complete as that in any modern textbook of gynæcology.

FURTHER CHRISTIAN PHYSICIANS

Another distinguished Christian medical scientist was Theophilus Protosbatharius, who belonged to the court of the Greek Emperor Heraclius, in the seventh century. He seems to have had a life very full of interest and surprisingly varied duties. He was a bishop, and, at the same time, commander of the imperial bodyguard, and the author of a little work on the fabric of the human body. The most surprising chapter in the history of the book is

that for some two centuries, in quite modern times, it was used as a text-book of anatomy at the University of Paris. It was printed in a number of editions early in the history of printing, at least one very probably before 1500, and several later.

There are very interesting phases of medicine delightfully surprising in their modernity to be found here and there in many of these early Christian writers on medicine. For instance, in a compend of medicine written by one Leo, who, under the Emperor Theophilus, seems to have been a prominent physician of Byzantium (the compend was written for a young physician just beginning practice), we find the following classification of hydrops or abdominal dilatation:" There are three kinds; the first is ascites, due to the presence of watery fluid, for which we do paracentesis: second, tympany, when the abdomen is swollen from the presence of air or gas. This may be differentiated by percussion of the belly. When air is present the sound given forth is like that of a drum, while in the first form ascites the sound is like that from a sack [the word used is the same as for a wine sack]; the third form is called anasarea, when the whole body swells."

It has often been the subject of misunderstanding as to why medicine should have developed among the Latin Christian nations so much more slowly than among the Arabs during the early Middle Ages. Anyone who knows the conditions in which Christianity came into existence in Italy will not be surprised at that. The Arabs in the East were in contact with Greek thought, and that is eminently prolific and inspiring. At the most, the Christians in

Italy got their inspiration at second hand through the Romans. The Romans themselves, in spite of intimate contact with Greek physicians, never made any important contributions to medical science, nor to science of any kind. Their successors, the Christians of Rome and Italy, then could scarcely be expected to do better, hampered especially, as they were, by the trying social conditions created by the invasion of the barbarians from the North. Whenever the Christians were in contact with Greek thought and Greek medicine, above all, as at Alexandria, or in certain of the cities of the near East, we have distinguished contributions from them.

ARABIAN CHRISTIAN PHYSICIANS

That this is not a partial view suggested by the desire to make out a better case for Christianity in its relation to science will be very well understood, besides, from the fact that a number of the original physicians of Arab stock who attracted attention during the first period of Arabian medicine, that is, during the eighth and ninth centuries, were Christians. There are a series of physicians belonging to the Christian family Bachtischua, a name which is derived from Bocht Jesu, that is, servant of Jesus, who, from the middle of the eighth to the middle of the eleventh century, acquired great fame. The first of them, George (Dschordschis), after acquiring fame elsewhere, was called to Bagdad by the Caliph El-Mansur, where, because of his medical skill, he reached the highest honors. His son became the body-physician of Harun al-Raschid.

In the third generation Gabriel Daskibril) acquired fame and d much as had his father and grandfather, for the medicine of the time, by translations of the Greek physicians into Arabian

These men m&T well be said to have introduced Greek medicine to the Mohammedans. It was their teaching that aroused Moslem scholars from the apathy that had characterized the attitude of the Arabian people toward science at the beginning of Mohammedanism. As time went on. other great Christian medical teachers distinguished themselves among the Arabs. Of these the most prominent was Messi the eider, who is also known as Janus Damascerns. Both he and his father practised medicine with great success in Bagdad, and his son became the body-physician to Harun al-Raschid either after or in conjunction with Gabriel Bachtischua. Like his colleague or predecessor in official position, he, too, made translations from the Greek into Arabic. Another distinguished Arabian Christian physician was Serapion the elder. He was born in Damascus, and flourished about the middle of the ninth century. He wrote a book on medicine called the "Aggregator," or "Breviarium," or Practica Medicinæ," which appeared in many printed editions within the century after the invention of printing. During the ninth century, also, we have an account of Honein Ben Ischak, who is known in the West as Johannitius. After travelling much, especially in Greece and Persia, he settled in Bagdad, and, under the patronage of the Caliph Mamum, made many translations. He translated most of the old Greek medical writers,

and also certain of the Greek philosophic and mathematical works. The accuracy of his translations became a proverb. His compendium of Galen was the text-book of medicine in the West for many centuries. It was known as the "Isagoge in Artem Parvam Galeni." His son, Ishac Ben Honein, and his nephew, Hobeisch, were also famous as medical practitioners and translators.

Still another of these Arabian Christians, who acquired a reputation as writers in medicine, was Alkindus. He wrote with regard to nearly everything, however, and so came to be called the philosopher. He is said altogether to have written and translated about two hundred works, of which twenty-two treat of medicine. He was a contemporary of Honein Ben Ischak in the ninth century. Another of the great ninth-century Christian physicians and translators from the Greek was Kostaben Luka. He was of Greek origin, but lived in Armenia and made translations from Greek into Arabic. Nearly all of these men took not alone medical science, but the whole round of physical science, for their special subject. A typical example in the ninth century was Abuhassan Ben Korra, many of whose family during succeeding generations attracted attention as scholars. He became the astronomer and physician of the Caliph Motadhid. His translations in medical literature were mainly excerpts from Hippocrates and Galen meant for popular use. These Christian translators, thoroughly scientific as far as their times permitted them to be, were wonderfully industrious in their work as translators, great teachers in every sense
