Veterinary medicine. 956 Osteomalacia, marrow much reddened and studded witli punctiform liemor- rhages; if cachexia already exists the bone marrow is pale, e-elatinous, even watery (marrow-fluid). The flat and_ short bones are also brittle" or flexible; owing to the dilation of the marrow spaces the spongy structure of these bones is em- phasized and may contain fair-sized marrow spaces. The sound of the bones is duller than that of normal bones. In osteomalacia of equides and hogs a considerable bulg- ing of the skull bones is also often observed. It is less fre- quent in goats and dogs. All skull bones appear enlarged symmetrically on both sides and the periosteum is easily pealed off. The surface of the liones is reddened, at times discolored dark- or blue-red and contains numerous small holes which are often con- fluent ; the outer lamella of the bones is soft and easily cut. These changes are particu- larly striking in the superior maxilla which may bulge out so much that the molars are imbedded in the reddish, rather fibrous bone mass down to their masticating surfaces. The weight of the macerated head is usually much dimin- ished (in horses 400-1160 gm., as compared with the normal weight of 4000 gm. [Marcone]) ; only if the bulging is excessive is the normal weight main- tained after maceration. The bone cavities are small or en- tirely obliterated. In consequence of atrophy and softening of the bony tis- sue the bones are subject to all sorts of deformities. These are most striking in the pelvis, the acetabula of which appear pressed inward, while the ilia are much bent (Figs. 165 and 166) ; on the verteljral column scoliosis, kyphosis and lordosis are to ))e noted and the depression of the ribs causes the thorax to become narrow and tlie sterura to protrude. The pelvic bones, and still more the long bones and the ribs often show recent or old fractures, callus formation, and ci
