 230 MOEBID ANATOMY.

periosteal deposit. On section, the walls are thin and can- cellated, the cavity large, and the whole is very light. 1847. Dr. J. C. Warren.

1260. Metacarpal bone of an animal (Bos), from New Orleans ; long, section. Very greatly enlarged by periosteal deposit, of which the max. thickness, at the lower extremity, is 1J in. ; outer portion to some extent compact, but structure otherwise very coarsely cancellated. Surface generally rough and reticulated, with deep grooves for the tendons, but comparatively regular in front. Anchylosed to the first phalanx of each toe ; and behind these is a very large and most irregular growth of new bone ; very little more than the articular surfaces of the phalanges being seen. Structure very solid ; that is, nowhere light and crumbling. 1866. Dr. H. R. Storer.

1261. Caries of the temporal bone, from a case of phthisis ; and explaining the chronic otorrhoaa that is occasionally ob- served in this disease. From a hospital patient, twenty- nine years of age (206, 71) ; and who had had a discharge from the ear from childhood. The bone was felt denuded through the meatus ; the tympanum was destroyed, and there opened into it an abscess of the size of a pea. There was serum in the cells of the bone, but no distinct tubercu- lar deposit. Sections -have been made, and the bone dried. 1859. Dr. J. B. S. Jackson.

1262. An upper molar tooth, with a portion of carious alveolus between the fangs. From a middle-aged man, who looked Healthy, but complained of weakness. For about a fort- night his teeth had been loose, and of several that he had picked out, all had more or less of the alveolus attached to them. The gums were spongy, tender, but not painful, and bled on the slightest pressure. No cause known for disease. Under the use of the chlorate of potash, he was very soon relieved. 1863. Dr. G. W. Pease.

1263. Enlargement of the lower portion of the radius, with ex- tensive caries just above the articular surface. Structure rather light and porous. 1847. Dr. J. C. Warren.
