To most people it would seem absolutely out of the question that such surgical procedures could be practised in the fourteenth century. We have the definite record of them, however, in a text-book that was the most read volume on the subject for several centuries. Most of the surprise with regard to these operations will vanish when it is recalled that in Italy during the thirteenth century, as we have already seen, methods of anaesthesia by means of opium and mandragora were in common use, having been invented in the twelfth century and perfected by Ugo da Lucca, and Chauliac must not only have known but must have frequently employed various methods of anaesthesia. In discussing amputations he has described in general certain methods of anaesthesia in use in his time, and especially the method by means of inhalation. It would not seem to us in the modern time that this method would be very successful, but there is an enthusiastic accord of authorities attesting that operations were done at this time with the help of this inhalant without the infliction of pain. Chauliac says: "Some prescribe medicaments which send the patient to sleep, so that the incision may not be felt, such as opium, the juice of the morel, hyoscyamus, mandrake, ivy, hemlock, lettuce. A new sponge is soaked by them in these juices and left to dry in the sun; and when they have need of it they put this sponge into warm water and then hold it under the nostrils of the patient until he goes to sleep. Then they perform the operation." Many people might be prone to think that the hospitals of Chauliac's time would not be suitable for such surgical work as he describes. It is, however, only another amusing assumption of this self-complacent age of ours to think that we were the first who ever made hospitals worthy of the name and of the great humanitarian purpose they subserve. As a matter of fact, the old-time hospitals were even better than ours or, as a rule, better than any we had until the present generation. In "The Popes and Science," in the chapter on "The Foundation of City Hospitals," I call attention to the fact that architects of the present day go back to the hospitals of the Middle Ages in order to find the models for hospitals for the modern times. Mr. Arthur Dillon, a well-known New York architect, writing of a hospital built at Tonnerre in France, toward the end of the thirteenth century (1292), says: "It was an admirable hospital in every way, and it is doubtful if we to-day surpass it. It was isolated; the ward was separated from the other buildings; it had the advantage we so often lose of being but one story high, and more space was given to each patient than we can now afford.
