to the development of the most dangerous diseases, since they do not teach the evil which the injudicious use of movements may produce." It was the harmonious and equable increase of all the voluntary and some of the involuntary muscles which the Swedish system sought to attain. The authority just quoted, in continuation, says:--"Notwithstanding bodily exercises under the name of _Turnen_ were generally known and practised in Germany at the beginning of the present century, and many of its enlightened professional writers tried to give to them a proper direction by combining them with anatomy and physiology, Ling must be considered as the founder of the rational system of movements." We have all seen deformed gymnasts, with square shoulders and lank loins, or with some particular group of muscles projecting in ugly prominences from the violated outlines of nature. All this the followers of Ling claim that he avoided or overcame. His gymnastics were introduced years ago, not only into all the military academies of Sweden, but into all town-schools, colleges, and universities, and even orphan-asylums and country-schools. Three objects are asserted to be obtained by his disciples: development of muscular fibre, increased arterialization, and improved innervation. Increase of function promotes the growth and capability of organic structures, and causes an augmented afflux of arterial blood and nervous influence to the part. The ambitious reformer of the gymnasium did not pause here; but, pursuing a still bolder course, undertook "to make gymnastics not only a branch of education for healthy persons, but to demonstrate them to be a remedy for disease." The new science was called _Kinesipathy_, or the "motor-cure." The curative movements were first practised in 1813, while Ling remained at Stockholm. A motor-hospital was established in connection with the gymnasium; and to accommodate the invalid and the feeble, new exercises, called "passive movements," were devised. These were executed by an external agent upon the patient,--that agent being usually the hand of the physician. The sick man, too weak for violent, voluntary effort, was stretched and champooed, the muscles of his trunk and limbs alternately flexed and extended by another person, until he gradually acquired strength to use active movements. As he gained power, he increased the voluntary resistance which he made to the operator, and thus, at the same time, the amount of his own muscular exertion. It is claimed that volition is thus called forth to neglected parts, and their innervation and vascularity increased; and that so at length the normal fulness of life and function is restored. This system confines itself mostly to chronic diseases. In the paralysis of the young, in defective volition from hysteria, in impaired local nutrition, in local deformities dependent on muscular contraction, and in lateral curvature of the spine, it unquestionably often produces the best results. Its
