    it with seeming benefit, but the swelling returned and increased rapidly. The operation was permanently successful. (From Museum of Robert Liston.) 3. Part of the left ramus of a lower jaw, from the interior of which has grown a tumour about the size of a hen’s egg. A small portion of the tumour projects through the internal, but the greater part through the external, wall of the ramus. A vertical section which has been made nearly through its outer part shows the interior structure to be that of a multi- locular cyst. The cavities are mostly of small size, and divided from each other by strong fibrous septa, containing numerous spicula and plates of bone, with no very definite arrangement. The ulcerated socket of a molar tooth passes down into the sub- stance of the tumour at the centre of that portion of the jaw from which it springs. The margin of the socket is surrounded by raised and infiltrated mucous membrane. 2199 In microscopic structure the tumour resembles the preceding specimen. 4. The symphysis and part of the body of a lower jaw, occupied by a multilocular cystic tumour. Upon the anterior surface two large cysts with smooth walls are exposed. A section, removing the posterior wall of the bone, shows that its cancellous tissue is occupied by many cysts of various sizes filled with a reddish granular solid material. The left incisor teeth had fallen out. 2200 The tumour consisted microscopically of large and small alveolar spaces filled with epithelial cells, and also of tortuous columns of similar cells, lying in a matrix of fibrous tissue. The masses and columns were composed of round epithelial cells with an external lining of elongated cells. The cells had in places undergone colloid degeneration. An ingrowth of the epithelium of the gum was observed near the socket of the left incisor tooth. From a woman in whom the disease had been observed for five years. (Presented by Sir Wm. Fergusson, 1870.) 5. The right half of a lower jaw, with a portion of its left side, including the left incisor teeth, removed by operation. A multilocular cystic tumour, developed in the interior of the bone, extends from the middle of the ascending ramus to the right incisor tooth. It is of an elongated oval form, and projects equally on
