The one fault in the constitution of Forrest was the gouty diathesis he inherited from his grandfather on the maternal side. This rheumatic inflammability—a contracted and congested state of some part of the capillary circulation and the associated sensory nerves accumulating force to be discharged in hot explosions of twinging agony—might have been cured by an æsthetic gymnastic adapted to free and harmonize all the circulations,—the breath, the blood, the nerve-force. But, unfortunately, his heavy and violent gymnastic was fitted to produce rigidity rather than suppleness, and thus to cause breaks in the nervous flow instead of an equable uniformity. This was the secret of his painful attacks and of his otherwise unexpectedly early death. There are three natures in man, the vital nature, the mental nature, the moral nature. These natures express and reveal themselves in three kinds or directions of movement. The vital nature betrays or asserts itself in eccentric movement, movement from a centre; the mental, in acentric movement, movement towards a centre; the moral, in concentric movement, movement around a centre. Outward lines of motion express vital activity, inward lines express mental activity, curved lines, which are a blending of the two other, express moral or affectional activity. This physiological philosophy is the basis of all sound and safe gymnastic. The essential evil and danger of the heavy and violent gymnastic of the circus and the ring is that it consists so largely of the outward and inward lines which express the individual will or vital energy and mental purpose. Each of these tends exclusively to strengthen the nature which it exercises. Straight hitting, pushing, lifting, jumping, in their two directions of exertion, tend to expand and to contract. That is vital, and this is mental. Both are expensive in their drain on the volition, but one tends to enlarge the physical organism, the other to shrink it and to produce strictures at every weak point. The former gives a heavy, obese development; the latter an irritable, irregular, at once bulgy and constricted development. The vice of the vital nature dominating unchecked is gluttony, and its end, idiocy. The vice of the mental nature is avarice, both corporal and spiritual, and its end, madness. The vice of the moral nature, when it becomes diseased, is fanaticism; and its subject becomes, if the vital element in it controls, an ecstatic devotee; if the mental element controls, a reckless proselyter. Now, a true system of gymnastic will perfect all the three natures of man by not allowing the vital or the mental to domineer or its special motions to preponderate, but blending them in those rotatory elliptical or spiral movements which combine the generous expansion of the vital organs and the selfish concentration of the mental faculties in just proportion and thereby constitute the language of the moral nature. Rigid outward movements enlarge the bulk and
