cific infections—syphilis(Fig. 28), tuberculosis (Fig. 27), leprosy, glanders, etc.—but they may also arisefrom non-specific agencies occurring in tissues possessing unusual susceptibilityto such changes. This is observed in the chronic venous stasis of the leg belowthe knee which is dependent upon varicose veins, in which condition the ulceris prevented from carrying on repair by the state of the circulation and nutri-tion of the part. Indeed, varicose ulcer of the leg presents the characteristics 176 AMERICAN PRACTICE OF SURGERY. of the typical chronic ulcer (see Plate XI). Another type of non-specific chroniculcer is seen in chronic gastric ulcer, where cicatrization is held in abeyanceprobably by some abnormal condition of the stomach secretions. A very frequent cause of chronic ulceration is to be found in the obstacleswhich interfere with the contraction of the ulcer—obstacles which are presentin leg ulcers and more especially in ulcers of the scalp.

(Original.) of the scalp is not prone to ulceration, but when this once occurs the processis apt to be slow and may extend over a period of years. This tardiness inhealing is due to the character and anatomical relations of the tissues of whichthe scalp is composed, the granulations at an early stage fixing the marginsof the ulcer to the deeper structures, and preventing that contraction of the edgeswhich is necessary for its perfect cicatrization. Some of the subvarieties of ulcer are the following: ULCER AND ULCERATION. 177 (a) Simple C//cer.—Simple ulcer is not due to any specific cause, but is theresult of a variety of local condition
