Dr. White has said just the opposite of this in a well-known passage of his book, in which he assures his readers that "in proportion as the grasp of theology upon education tightened, medicine declined; and in proportion as that grasp relaxed, medicine has been developed." The reason for such a statement is that he knew nothing about the history of medicine and surgery in these medieval centuries and thought there was none. This is a characteristic example of his mode of writing the History of the (Supposed) Warfare of Theology with Science in Christendom. This much will give some idea of the value of his book as a work of reference. After knowing something of these wonderful developments of medieval medical science, it is to be hoped that no one will listen hereafter to the ignorant assertions of those who talk of the suppression of medical knowledge at this time. _William of Salicet and Lanfranc were both of them clerics,_ that is, they belonged to the ecclesiastical body and had taken minor orders, though they were not priests, as priests were for obvious reasons not allowed to do surgical operations, it being as repugnant to human feelings in the Middle Ages as it is now, that {9} the messenger of Divine Mercy should handle the knife and spill blood, or that the pastor of souls should come straight from the operating room to bring consolation to the afflicted and the dying. Much more might be said about the wonderful medical teaching of the thirteenth century. The men who made the universities what they have continued to be down to the present time, had open minds for any great advances that might come. Accordingly, when the histories of anesthesia tell us that there was a form of anesthesia introduced during the thirteenth century by Ugo da Lucca, and that even some method of inhalation was employed for this purpose, it will be a surprise only to those who have never properly realized all that our educational forefathers of the early university days succeeded in accomplishing.
