or localized irritation ojnerve-plates in the area of disease,producing spasms of groups of mus-cles receiving nerve-supply from thesame common tract. The question of nerve destruc-tion within the joints quite surelyplays an important part in determin-ing deformities occurring in circum-scribed foci of disease. But afterthe entire joint becomes involved,the element must be left out of thequestion only so far as generalspasm is produced in all musclesabout the joint. I quote from aletter of Dr. Towle, Professor ofAnatomy in the University of Vir-ginia, which seems to demonstratethat the nerve-supply comes fromdifferent trunks. As to nervous supply of hip,what I have seen is as follows: Theobturator immediately on emergingthrough the obturator foramen gives off a branch which pierces the capsule; the sacral plexusor the upper part of great sciatic, gives off two small branches which enter the back ofthe capsule, the nerve to obturator interims, from sacral plexus, leaving through great

When the limb becomes Jlexed, the abductors begin immediately to lose their poweras abductors, and in proportion to Jlexion become inward rotators. Figs. 8 and 9, taken from the dissections, represent the glutaeus medius, with the limb in a straight position,and then flexed to thirty-five degrees. In Figure8 the muscle acts as anabductor, while in Figureq its action is changedto that of an internalrotator when the limbis Jlexed to thirty-fivedegrees. Figs. 10 and 11 arefrom photographs of ourdissections of the glutaeusminimus. In Fig. 10, thelimb straight, the muscleacts as an abductor; where-as the limb being flexedonly fifteen degrees, itj becomes a powerful internalrotator and increases inpower as the limb flexes,as does the tensor vaginaefemoris (see Fig. 11): theoutward rotators becomeabductors when th
