Much more is known about the medieval anticipation of other specialities--those of the throat and nose, and eye and ear--and the surprise is with regard to dentistry, which is usually quite unknown. The fact, however, that dentistry developed so much more than is usually thought prepares the mind for the anticipations in other departments. Following that of dentistry should come naturally the mouth and throat, and it happens that the men whose writings in dentistry are known also touched on these subjects. The medical writers of the early Middle Ages, particularly Aëtius, Alexander of Tralles, and Paul of Ægina, have not a little to say with regard to affections of the throat and nose, and the eye and ear. Alexander's chapter on the Treatment of Affections of the Ear, Gurlt considers ample evidence of large practical experience and power of observation. Alexander describes the ordinary mode of getting water out of the external auditory canal by standing on the leg corresponding to the side in which the water is, and kicking out with the opposite leg. Foreign bodies should be removed by an ear spoon, or a small instrument wrapped in wool and dipped in sticky material. He suggests sneezing with the head leaning toward the side on which the foreign body is present. Insects or worms that find their way into the ear may be killed by injections of dilute acid and oil or other substances. Paul of Ægina has a very practical technique for the removal of fish-bones or other objects caught in the throat. He also gives the detailed technique of opening the larynx or trachea, with the indications for this operation. He also describes how wounds of the neck should be sewed after attempts at suicide. In a word, the more one knows of these old-time medieval writers of the sixth and seventh centuries the clearer it becomes that they had learned their lessons well from the ancients, and passed on an excellent tradition to their colleagues of succeeding generations. If these lessons were not properly taken, it was because the disturbance of civilization caused by the coming down of the Teutonic invaders into Italy took away interest in the things of the mind and of the body, until the coming of another upward turn in progress.
