Rhases, upon the authority of a surgeon called Ancilisius, in the barbarous translation of his works, which probably is a corruption of Antyllus, briefly describes this operation. He directs us to open the mouth and take hold of the tonsils, the fourth part of which may be cut off. He recommends us to make the patient gargle with vinegar. He forbids the operation when the tonsils are enlarged and red. (Contin. vii, 2.) Haly Abbas (Pract. ix, 36,) and Mesue (de Ægr. Gutturis, 4,) describe the operation, but not so minutely as Albucasis. Guido de Cauliaco copies the descriptions of Albucasis and Haly Abbas. (c. vi, 2.) SECT. XXXI.—ON THE UVA. The uvula being, as it were, the quill or plectrum of the organ of speech is often the seat of defluxion from the head, and becoming preternaturally enlarged, of a lengthened form and slender shape, it is called columella; but when thick below and round it is named uva, from its resemblance to a grape, as the other is so called from its resemblance to a column. If, therefore, it cannot be made to yield to general treatment,—I mean evacuations by bleeding and purging,—nor to topical, such as astringents, repellents, and discutients,—we must proceed to the operation, lest, by its constant irritation, it bring on coughs, sleeplessness, and even suffocation. Such, therefore, as are contracted, round, not of a lengthened shape, bloody, or somewhat black, we must decline operating upon; but those that are slender, long, small at the extremity, loose, not very bloody, but whitish, we must operate upon; for the inflammation of them soon subsides. We must only take away as much of the uva as exceeded its natural size; for the complete extirpation of it proves greatly injurious to the parts about the chest, and occasions the loss of voice. Wherefore, having placed the patient on a seat in the rays of the sun, and directed him to gape wide, we seize with the forceps adapted for this purpose, or a common tenaculum, upon the redundant part and drag it downward, and cut it out with the instrument called staphylotomus, or the scalpel used in the operation for the suture of the upper eyelid. After the operation the same things are to be done as are recommended for angiology. But since often, from the timidity of the patient, or the fear of the hemorrhage, or the success attending the treatment by medicines, he declines the operation by instruments, we may rather consume it by means of a caustic medicine. Wherefore, taking the caustic used for burning the eyelids, or some such, we are to fill with it the hollows of the instrument called staphylocaustos, and directing the patient to gape wide, and getting the tongue pressed down with a tongue spatula, we open the instrument sufficiently and grasp with it as much of the uva as we cut off in the other operation. The medicine must neither be of too liquid a consistence, lest it run down from the uva improperly, and burn the
