    11. Multiple cystic tumour of lower jaw. The bone is greatly expanded, and in places completely absorbed. 391 Microscopical appearance as in No. 389. (Mr. James Lane.) 12. A growth springing from near the alveolar margin, and involving the greater part of the body of the lower jaw. Opposite the symphysis the growth projects in front and behind, and has caused absorption of the bone, except at its lower border. The cut surface shows the presence of small cysts. The minute structure resembles Nos. 389, 390 and 391. 392 13. Growth of the lower jaw, springing from the symphysis and neighbouring parts and projecting forwards. Septa run in from the capsule. 393 There are numerous cysts which# resemble histologically those of the preceding specimens. (Mr. Owen.) Lent by University College. 14. The outer half of a large cystic tumour, which involved the lower jaw. The subcutaneous surface is recog- nizable by the portion of the masseter adhering to the tumour. On this surface openings have been made into two large cysts, both of which have thick mem- branous walls and a smooth interior. On the opposite side of the specimen the parts have been divided through a large cyst, from the sides of which there project nodules and lobulated outgrowths of tumour substance. The cut surface of the solid portions of the tumour and of the intracystic growths, as best seen on the left of the preparation, presents small, closely set spaces of various forms, and filled with a soft granular material, giving to the whole a gland-like structure. The bone has for the most part disappeared before the growth which has invaded it. 1400 Microscopic Structure.—A section of the solid part of the growth presents a scanty fibrous stroma enclosing large spaces occupied by masses of epithelial cells. The peripheral cells present in parts a columnar shape, whilst the remaining cells are either small and branched or spindle-shaped. From a man, aged 22, who was admitted into U. C. H. on July 10, 1871, under the care of Mr. Heath. Six years previously patient first noticed a small hard swelling on the right side of the lower jaw. The tumour steadily increased in size, and had been lanced and tapped several times in the mouth. On admission the right side of the face presented a large, smooth, globular swelling reaching forwards to the angle of the mouth, backwards to an inch behind
