    Moos, S., The ]-Iistological Changes of the Eustachian Tube in Chronic Catarrh. (Trans, by Dr. A. N. Blodgett.) Arch. Ophthal. and Otol., V., 1876, pp. 542-560, pll. I. and II. A case treated for Eustachian tube stenosis, at intervals for 10 years, came to autopsy. Normal and pathological anatomy of the tubes described. Moos, S., Beitrage zur Normalen und Pathologischen Anatomie und zur Physiologie der Eustachischen Rohre. Weisbaden, 1874, p. 53, pi. VI. The tube when at rest is closed at a point just behind the funnel-shaped end of the faucial open- ing and this closure extends through aliout two-fifths of the length of the canal. On the lower surface, or floor, of the tube the closure is effected by the longitudinal folds of mucous membrane which form a considerable prominence, really a valve of variable size. On the opposite surface of the canal, below the cartilaginous hook, in the lower portion of the canal, is another prominence of mucous membrane smaller than the other. These have their analogy in the lower animals. They probably facilitate the patescence of the canal by their unrolling. The cartilaginous “islands” of the tube are divided into five classes, the most important being those on the floor and sides of the tube. Those on the sides consist always of fibro-cartilage. They assume here the function of sesamoid bones in the tubal mechanism through their attachments. Myles, R. C., Adhesions Connecting the Eustachian Tube to the Pharyngeal Wall above. Arch, of Otol., XXVI., 1897, pp. 322-323. Two cases reported in which there were adhesions connecting the Eustachian tube to the walls of the pharynx, forming a number of cavities (recesses?). The adhesions were torn with the finger with relief of symptoms. Nicoladoni, C., Beobachtung am Lebenden uber die Bewegung der Tuba Eustachii. Monatschr. fiir Ohrenheilk Aug., 1875. A favorable opportunity for observing the movements of the Eustachian tube was presented by the performance of an operation on a tumor of the naso-pharynx by first removing the upper jaw. “Simultaneously with the contact of the soft palate with the posterior pharyngeal wall, its posterior surface being almost in line with the floor of the nose the medial portion of the tul)e, about one millimetre in height, began its movement while the lateral portion appeared to remain at rest. The movement, rather rapidly performed, consisted in an elevation for about three millimetres of the lower prominent edge of the medial portion which appeared
