judgment is decisive in favor of rest, judiciously applied; and my view 

 of what constitutes a judicious application of rest has been more than 

 once presented in these pages. There are degrees of this rest. One 

 contemplates simple immobility in a narrow stall. Another means the 

 enforced mobility of the slings and a narrow stall as well. Another a 

 box stall, with ample latitude as to posture and space, and option to 

 stand up or lie down. As wide as this range maj- appear to be, radical 

 recovery has occurred under all of these modified forms of letting our 

 patients alone. 



The etiolog}" of injuries and diseases of the hip is one and the same 

 with that of the shoulder. The same causes operate and the same 

 results follow. The onh' essential change, with an important excep- 

 tion, which would be necessary in passing from one region to the other 

 in a description of its anatomy, its phvsiolog}', and its pathology, 

 would be a substitution of anatomical names in reference to certain 

 bones, articulations, muscles, ligaments, and membranes concerned in 

 thQ injuries and diseases described. It would be only a useless repeti- 

 tion to cover again the ground over which we have so recently passed 

 in recital of the manner in which certain forms of external violence 

 (falls, blows, kicks, etc.) result in other certain forms of lesion (luxa- 

 tion, fracture, periostitis, ostitis, etc.), and to recapitulate the items 

 of treatment and the names of the medicaments proper to use. The 

 sames rules of diagnosis and the same indications and prognosis are 

 applicable equallj' to every portion of the organism, with only such 

 modifications in applying dressings and apparatus as may be required 

 by differences of conformation and other minor circumstances, which 

 must suggest themselves to the judgment of every experienced observer 

 when the occasion arrives for its exercise. 



There is an exception to be made, while considering the subject in 

 connection with the region now under advisement, in respect to the 

 formidable affection known as morbus coxarius, or hip-joint disease; 

 and leaving the detail of other lesions to take their place under other 

 heads, that relating to the shoulder, for instance, we turn to the hip 

 joint and its ailments as the chief subject of our present consideration. 



fS'i/mj)fo)/is. — In investigating for morbus coxarius, let the observer 

 firsts examine the lame animal b}^ scanning critically the outlines of the 

 joint and the region adjacent for any difference of size or disturbance 

 of sj-mmetry in the parts, any prominence or rotundity, and on both 

 sides. The lame side will probably be warmer, more developed and 

 fuller, both to the touch and to the eye. Let him then grasp the 

 lower part of the leg (as he would in examining a case of shoulder 

 lameness) and endeavor to produce excessive passive motion. This 

 will probably cause pain when the leg is made to assume a given
