some medical recipes at the end by Francis Verney. It was probably written in the fifteenth century. Its title is:

"The inventorie or the collectorie in cirurgicale parte of medicine compiled and complete in the yere of our Lord 1363, with some additions of other doctours, necessary to the foresaid arte or crapte (crafte?)."

What we find in the period of manuscripts, however, is as nothing compared to the prestige of Guy de Chauliac's work, once the age of printing began. Nicaise was able to find sixty different printed editions of the "Great Surgery." Nine others that are mentioned by authors have disappeared and apparently no copies of them are in existence. Besides there are sixty editions of portions of the work, of compendiums of it and commentaries on it. Altogether 129 editions are extant. Of these there are sixteen Latin editions, forty-three French, five Italian, four Low Dutch, five Catalan, and one English. Fourteen appeared in the fifteenth century, thirty-eight in the sixteenth century, and seventeen in the seventeenth century. The fourteen editions belonging to the incunabula of printing, issued, that is, before the end of the fifteenth century, show what lively interest there was in the French surgeon of the preceding century, since printing presses at this precious time were occupied only with the books that

'In Nicaise this last word is written crapte. I have ventured to suggest crafte, since a misreading between the two letters would be so easy. In the same way I have suggested tentatively a changing of the z in the title of the Bibliothèque Nationale copy to y, making the word yere instead of zere.

were considered indispensable for scholars. The first edition of the "Great Surgery" was printed in 1478 at Lyons. Printing had only been introduced there five years before. This first edition, primus primarius or editio princeps, was a French translation by Nicholas Panis. In 1480 an Italian edition was printed at Venice. The first Latin edition was printed also in Venice in 1490.

It would be only natural to expect that the successors of Guy de Chauliac, and especially those who had come personally in contact with him, would take advantage of his thorough work to make still further advances in surgery. As matter of fact, decadence in surgery is noted immediately after his death. Three men taught at the University of Montpellier at the end of the fourteenth and the beginning of the fifteenth century, John de Tornamira, Valesco de Taranta, and John Faucon. They cannot be compared, Gurlt says, with Guy de Chauliac, though they were physicians of reputation in their time. Faucon made a compendium of Guy's work for students. Somehow there seemed to be the impression that surgery had now reached a point of development beyond which it could not advance. Unfortunate political conditions, wars, the withdrawal of the Popes from Avignon to Rome, and other disturbances, distracted men's minds, and surgery deteriorated to a considerable extent, until the new spirit at the time of the Renaissance came to inject fresh life into it.

MEDIEVAL DENTISTRY-GIOVANNI OF

ARCOLI

If there is one phase of our present-day medicine and surgery that most of us are likely to be quite sure is of very recent development it is dentistry. Probably most people would declare at once that they had every reason to think that the science and art of dentistry, as we have it now, developed for the first time in the world's history during the last generation or two. It is extremely interesting to realize then, in the light of this almost universal persuasion, founded to a great extent on the conviction that man is in process of evolution and that as a consequence we must surely be doing things now that men never did before, to find that dentistry, both as an art and science, is old; that it has developed at a number of times in the world's history, and that as fortunately for history its work was done mainly in indestructible materials, the teeth themselves and metal prosthetic apparatus, we have actual specimens of what was accomplished at a number of periods in the olden times. Surprising as it will seem to those who hear of it for the first time, dentistry reached high perfection even in what we know as ancient history. It is rather easy to trace scientific and craftsmanlike interest in it during the

medieval period and in the magnificent development of surgery that came just at the end of the Middle Ages, dentistry shared to such degree that some of the text-books of the writers on surgery of this time furnish abundant evidence of anticipations of many of the supposedly most modern developments of dentistry.

There are a number of historical traditions with regard to dentistry and the treatment of the teeth in Egypt that can be traced back to good authorities in Egyptology of a generation or more ago, but it is rather hard to confirm the accounts we have by actual specimens; either none were found or for some reason those actually discovered are now not readily available for study. Among the Phenicians however, though we have good reasons to think that they learned their arts and crafts from the Egyptians, there is convincing evidence of a high development of dentistry. M. Ernest Renan, during an exploring expedition in Phenicia, found in the old necropolis at Sidon a set of teeth wired together, two of which were artificial. It was a striking example of bridgework, very well done, and may now be seen in the Louvre. It would be more than a little surprising, from what we know of the lack of inventiveness on the part of the Phenicians and their tendency to acquire their arts by imitation, if they had reached such a climax of invention by themselves. Since they adapted and adopted most of their arts and crafts from Egypt, with which they were in close commercial relations, it has been argued with some plausibility that the Egyptians may have had many modes of dental prosthesis, but removed all artificial

teeth and dental appliances from the mouth of corpses before embalming them, in preparation for the next world, because there was some religious objection to such human handiwork being left in place for the hereafter, as they hoped for it.

There is a well-authenticated tradition of intimate intercourse in a commercial way between the old Etruscans who inhabited the Italian hill country and the Phenicians, so that it is no surprise to find that the oldest of Etruscan tombs contain some fine examples of bridgework. An improvement has come over Phenician work however, and bands of gold instead of wire are used for holding artificial teeth in place. Guerini, whose "History of Dentistry" is the standard work on the subject, on a commission from the Italian government, carefully studied these specimens of Etruscan dental work in the museums of Italy, and has made some interesting observations on them. In one specimen, which is especially notable, two incisor teeth are replaced by a single tooth from a calf. This was grooved in such a way as to make it seem like two separate teeth. Guerini suggests a very interesting and quite unexpected source for this. While examining the specimen he wondered where the old Etruscan dentist had obtained a calf's tooth without a trace of wear on it. He came to the conclusion that he must have cut into the gums of a young calf before the permanent tooth was erupted in order to get this structure absolutely unworn for his purpose. A number of examples of bridgework have been found in the old Etruscan tombs. The dates of their construc
