Healthy ulcers, if very extensive, produce likewise considerable effects on the constitution. This is chiefly perhaps owing to the purulent action, which makes a part of the ulcerative one; for this morbid local secretory action induces a general change, in the same way as other acute changes, of either the formative action itself, or any other intimately connected with it, such as the interstitial. But, besides this cause, the granulating action, although healthy, co-operates with the diseased interstitial action, or the purulent part of the ulcerative action; because, although the granulations, or organic particles, be healthy, yet they are formed in an unnatural situation, and with greater rapidity, and in greater numbers, in a given time, than naturally they ought to be; and, therefore, the action of the part requires greater power for its continuance than is possessed. There is consequently, then, weakness produced, which, by association, affects the system, and co-operates with the diseased formative action, increasing the general disease. The consequence of this state, likewise, is, that the ulcer comes, after some time, to be rendered unhealthy, owing to the deficiency of power to support the necessary action; in which case, the granulating action comes to be also diseased, and co-operates still more with the former morbid condition of the interstitial vessels, or the purulent action, which, although a part of a healthy ulcerative action, is yet itself a morbid secretion, and an unnatural action. The effects of the ulcerative action on the constitution, are to be alleviated by good diet, free air, and the other remedies which have been pointed out when formerly considering hectic, to which I now refer. I shall only observe, that some of these remedies are employed occasionally with little judgment, and when they are not indicated. It is, for instance, a common practice with some, to prescribe the bark for the cure of every ulcer, whether the constitution be affected or not. But, from many trials, I am confident that it is of very little service, unless when a general disease, whether it be called weakness or hectic, exists. When the proper remedies for the cure of hectic, conjoined with necessary local applications, fail, the diseased part must be removed; but, before doing so, it is, in every instance, proper to form a pea issue, in order still to keep up a secretory action, the good effects of which have been already noticed. The restlessness, and febrile symptoms, which are sometimes produced by painful sores, are best relieved by anodynes. _Of the Cure of the Inflammatio Debilis, and the Treatment of Mortification._
