 acquainted with the anatomy of tlie aaimai. A m<»- 

 deriitely firm extension should be made by two persons; 

 one holding the body and one part of the joint, and 

 the ol her the immediate dislocated limb. If this ex- 

 tension is sufficiently and properly maUe, the dislo- 

 cated bone will slip into its socket, and t!ie limb be 

 found perfect. When the shoulder is dislocate;?, 

 which is a very rare occurrence, it may be forwards or 

 backwards. It is generally forwards. Tlie elbow 

 may be dislocated either inwards or outwards ; it is 

 more usually inwai'ds. The hip is more frcqrient'y 

 dislocated than eitijer of the former cases, and it more 

 generally happens tliat the head of the thigh bone is 

 carried uj)wurds and backwards. In which case it 

 makes the hip of that side sensibly higher and more 

 backward than the other, and hence it becomes easily 

 detected. The muscles of the loins are so strong, 

 that reduction of the thigh is exceedingly ditficult. 



The knee joint, that is the joint next the hip, is 

 also subject to dislocation ; and this is more fre- 

 quently inward than outward; and, from the strength 

 of the surrounding muscles, it is often found diificult 

 to reduce. It is but seldom the elbow is dislocated 

 without u fracture also. Wlien a dislocation hi^s been 

 reduced, then a pitch plaster should be judiciously ap- 

 plied to the part to keep it in its place.
