This recapitulation of the salient features of the practice of the Retreat renders it easy to understand the position taken by the managers of the institution in regard to mechanical restraints. When kindness failed to subdue maniacal excitement, when medical remedies exerted no calming influence, mild forms of restraint were reluctantly adopted, rather than maintain a conflict between patient and attendant. It appears from the Retreat archives that not more than five per cent., reckoning the night as well as the day, were restrained by strap or waistcoat.[136] It is notorious that, at the same period, it was the custom in some asylums, probably many, to chain to the bedstocks, at night, every patient in the house. Ferrus, to whom I have referred, did not find camisoles in use at St. Luke's in 1826, but "strong chains were employed to hold the excited patients. These chains, fixed at different heights to the sides of stoves (_chauffoirs_), have iron rings at the end, by means of which the arms or the legs of the patient are rendered completely immovable.... Far from fearing that a painful impression will be produced on the patients by chains, they think, on the contrary, that this apparatus exerts a beneficial influence upon them; that it intimidates, humbles them, and removes all desire to attempt to get rid of their fastenings." Ferrus says that at the Retreat he found a belt was employed, softly padded, to which the arms were attached. "We do not employ it in France," he says, "although it might in hot weather be preferable to the camisole.... The Retreat offers all the resources of art and the comforts of life (_douceurs de la vie_) compatible with the condition of insane persons."
