Note 60 — DISSERTATION II. CONTINUED. (continued 2)

This affection of the ulcer, produced by a disease of the parts below, is induced with a frequency nearly proportioned to the aptitude of the part below for becoming diseased, by the continuance of an ulcer over them. Tendons and bones are particularly apt to be injured in this way; and, therefore, ulcers seated over tendinous parts, or bones thinly covered, are more apt to affect these, and to be reacted on themselves, than when seated over fleshy parts. On the same account, ulcers on the foot, or ankle joint, are worse to heal than those a little farther up the leg; and the difference is greater than can be explained wholly, by the circumstance of distance from the heart, and possessing less power of performing action properly. Recent ulcers likewise heal easily on the feet, by proper treatment. It is old ulcers alone which are difficult to manage, and the cause is obvious.
