Produced by disease of the teeth. is the counterpart, precise!}, of ulceration of the soft parts, described in Section VII of the preceding chapter. Causes.—Tliese are very varied,—anything, in fact, that is capable of wounding or bruising the different parts of the body; or it may be simply the extension of some obstinate disease from an adjoining part. Symptoms.—There is generally a sinus or canal, from which pro- ceeds the odor of dead bone. The presence of decomposed bone may be easily detected by the black discoloration it produces on any article made of silver. There will also be a most sensible difference to the touch ; the bone will feel rough—perhaps, in places, almost like saw-teeth, whereas in health it is smooth. The parts most affected are the jaw and teeth, the sinuses of the head, and the poll, withers, ribs and tail. Treatment.—Remove the decaying bone, by scraping with any blunt surface, or with a bone scraper, the instrument which is shown in the cut. Various acids will remove a slouo;h, and leave a healino- surface. Hvdrochloric and nitro- muriatic acids are among the number. On account of their great strength, these must be applied with caution, by means of a small pad, and only to the decaying spots. Under ap- propriate treatment wounds of the jaw heal especially easily. In this disease, whenever the bojie is exposed, it should be protected from the air by the use of cotton batting. IV. Necrosis, or Mortification of a Bone. The difference between necrosis and caries is, that in the former there is death of a large part, or sometimes the whole, of the bone, while in the latter there is a gradual decay of only a small surface. This corresponds, as will be seen, to the difference between mortification and ulceration, as dis- criminated for the soft parts of the body a few pao;
