    disposition to particular hemorrhages arises from a frebleness, either original or acquired, in the vital en- ergy of the exhalants of the organ thus disposed ; so that, though the elective power of its exhalants might be adequate to the healthv force of the circulation, jet an increase of it from inflammation, or any other cause, would readily overcome the comparatively slight resistance offered by this power. Dropsical effusions. These often follow inflamma- tion, though it does not necessarily precede them. Like hemorrhages they would seem most frequently to depend on some change in the natural relations of the exhalants. They often, too, follow obstruction of the blood in some of the venous trunks, there appearing in such cases to be an effort on the part of the neigh- bouring exhalants to open a new passage to relieve the difficulty produced by the obstruction. Dropsies may also arise from an increased force of the circulation, and from an atony of the extreme ves- sels. Thus we see them induced by excessive action, and likewise by great prostration of the vital powers, as in the last stages of fever, consumptions, &c.; here they are at times vicarious with hemorrhage. The secretory capillaries are greatly affected in dis- ease. In fact, there is scarcely any complaint which occurs in the system, that does not produce, or is not accompanied by some alteration, either in the kind or degree of action, in some portion of the glandular ap- paratus ; so that the quantity and qualities of the secret- ed fluids are almost infinitely varied. Of what numer- ous changes the urine and bile are susceptible in differ- ent diseases, every one must have remarked. The
