 great trochanter, increased heat and swelling in that region, 

 are quite marked. The detection of crepitation over the 

 middle trochanter, best felt by resting the hand upon that 

 region and walking the horse at the same time, is to be 

 mainly relied upon. The writer has seen a number of these 

 cases in draft-mules obliged to do heavy and prolonged 

 backing. Crepitation with local changes must be looked 

 upon as pathognomonic, as mere swelling and pain in that 

 region, and even an oblique trot, may follow other diseases, 

 — for instance, old cases of fractured pelvis.
