In the subject of regular or irregular gout attention to the cause, that is, to disordered metabolism of the body as a whole and of the cardiac and arterial walls in particular, promotes, as we have seen, the recognised conditions of compensation: the etiological and pathological indications are here practically identical. In respect of exercise in detail, gentle walking on the level should be ordered to begin with, that is, exercise short of producing pain or oppression. The patient had better give up his regular work for a time, and take advantage as fully as possible of the leisure to enjoy the benefits of a healthy life in the fresh open air. Very shortly he will be able to ride, play golf, shoot and cycle slowly. A course of treatment at one of the best of our native spas or of the Continental watering-places sometimes makes a new man of the sufferer from gouty heart. The Nauheim treatment, whether taken there or in England, may also do real good. But it must not be employed indiscriminately, as is so often done. The profession ought to remember (what the public cannot and probably never will come to understand) that pathological diagnosis must precede rational treatment, which consists in applying a proper remedy to the individual case before us, not in fitting every case to a specialised system or panacea--the essence of quackery. In planning the treatment of the dilated heart of the middle-aged man who strained his circulation in youth and comes to us complaining of a recurrence of præcordial distress and breathlessness, we have to remember that there is left in the cardiac walls but a portion of that reserve of elasticity and that reserve of muscular energy which they normally possess and require to enable them to meet the stress of exertion. Let me remind you for a moment that, of the provisions which the heart possesses against such an emergency or other sudden or severe demand upon its capacity and activity, one is extensibility of its tissues, by virtue of which it accommodates within it the considerable increase in the charge of blood that is poured into it from the active muscles, and the residues that accumulate within it from insufficient discharge in the face of increased peripheral resistance. The walls yield before the increased internal pressure acting on them both _a tergo_ and _a fronte_; the heart is over-distended, with a passing sense of discomfort, dyspnœa and lividity; and when the muscular effort is ended the elasticity corresponding with extensibility of the walls presently insures the return of the chambers to their original dimensions. At the same time a second provision comes into operation. Increased muscular activity is developed in accurate proportion to the rise of internal pressure and secures sufficient output from the heart. This, I repeat, is what occurs in the sound heart. Now, in old parietal strain extensibility and the reserve of capacity of the chambers which it insures are seriously exhausted;
