Although a _full_ and _tense_ pulse is always an indication of the necessity of bleeding; yet I can easily conceive there may be such congestions, and such a degree of stimulus to the arterial system, as to produce a depressed, or a _low_ or _weak_ pulse. Two cases of this kind are related by Dr. Monroe, one of which was cured by bleeding. The same symptom of a low and weak pulse is often met with in the _first_ stage of pneumony, and apoplexy, and is only to be removed by the plentiful use of the same remedy. II. _Vomits_ have often been given with advantage in dropsies. Dr. Home says, that squills were useful in these diseases only when they produced a vomiting. By abstracting excitement and action from the arterial system, it disposes the lymphatics to absorb and discharge large quantities of water. The efficacy of vomits in promoting the absorption of stagnating fluids is not confined to dropsies. Mr. Hunter was once called to visit a patient in whom he found a bubo in such a state that he purposed to open it the next day. In the mean while, the patient went on board of a vessel, where he was severely affected by sea-sickness and vomiting; in consequence of which the bubo disappeared, and the patient recovered without the use of the knife. Mr. Cruikshank further mentions a case[39] of a swelling in the knee being nearly cured by a patient vomiting eight and forty hours, in consequence of his taking a large dose of the salt of tartar instead of soluble tartar.
