I have observed great benefit from the use of external remedies in dysentery, and these have, perhaps, been too much neglected by authors and practitioners. The warm bath is of great service, especially where the gripes and tenesmus are severe, and where the fever has been taken off by previous evacuation. Fomentations or warm applications of any kind to the abdomen give temporary relief; and it will be found of advantage to keep those parts, at all times, well defended from the cold air. Blisters to the abdomen were also found of use, and likewise acrid liniments, composed of oil, volatile spirits, and tincture of cantharides. Where the stomach has been much affected, I have perceived relief from fomenting it with stupes, upon which thebaic tincture and camphorated spirits were sprinkled, as recommended by Dr. Lind. I was once affected with a bad dysentery in the West Indies, and I thought myself much relieved by the warm bath and a blister. Strangury is not an uncommon symptom in this disease, independent of cantharides, and the most sensible and effectual relief is derived from fomentations to the pubis and perinæum, as I also experienced in my own case. What has been hitherto said regards chiefly the acute dysentery; but the most frequent and troublesome complaint that occurred at the hospital, was the same disease in what may be called its chronic state. There is a considerable variety of symptoms in all the stages of this disease, but particularly in the more advanced or chronic state, so that a corresponding variety is necessary in the modes of treatment, and there are few diseases in which there is more room for exercising the judgement.
