Of course, a still worthier change of mind has come over the attitude of educators because of the growing sense of appreciation for the wonderful work of the monks of the Middle Ages, and even of those centuries that are supposed to show least of the influence of these groups of men who, forgetting material progress, devoted themselves to the preservation and the cultivation of the things of the spirit. The impression that would consider the pre-Reformation monks in Germany as unworthy of their high calling in the great mass is almost entirely without foundation. Obscure though the lives of most of them were, many of them rose above their environment in such a way as to make their work landmarks in the history of progress for all time. Because their discoveries are buried in the old Latin folios that are contained only in the best libraries, not often consulted by the modern scientist, it is usually thought that the scientific investigators of these centuries before the Reformation did no work that would be worth while considering in our present day. It is only some {51} one who goes into this matter as a labor of love who will consider it worth his while to take the trouble seriously to consult these musty old tomes. Many a scholar, however, has found his labor well rewarded by the discovery of many an anticipation of modern science in these volumes so much neglected and where such treasure-trove is least expected. Professor Clifford Allbutt, the Regius Professor of physics at the University of Cambridge, in his address on "The Historical Relations of Medicine and Surgery Down to the End of the Sixteenth Century," which was delivered at the St. Louis Congress of Arts and Sciences during the Exposition in 1904, has shown how much that is supposed to be distinctly modern in medicine, and above all in surgery, was the subject of discussion at the French and Italian universities of the thirteenth century. William Salicet, for instance, who taught at the University of Bologna, published a large series of case histories, substituted the knife for the Arabic use of the cautery, described the danger of wounds of the neck, investigated the causes of the failure of healing by first intention, and sutured divided nerves. His pupil, Lanfranc, who taught later at the University of Paris, went farther than his master by distinguishing between venous and arterial hemorrhage, requiring digital compression for an hour to stop hemorrhage from the _venae pulsatiles_--the pulsating veins, as they were called--and if this failed because of the size of the vessel, {52} suggesting the application of a ligature. Lanfranc's chapter on injuries to the head still remains a noteworthy book in surgery that establishes beyond a doubt how thoughtfully practical were these teachers in the medieval universities. It must be remembered that at this time all the teachers in universities, even those in the medical schools as well as those occupied with surgery, were clerics.
