below the injury; the ready detection of crepitation— in a word, 

 the assemblage of all the signs and symptoms which have been 

 already considered as associated with the history of broken bones. 

 The fracture of the cubitus alone, principally above the radio- 

 cubital arch, may be ascertained by the aggravated lameness, the 

 excessive soreness on pressure, and perhaps a certain iacrease of 

 motion, with a very slight crepitation if tested for in the usual 

 way. Displacement is not likely to take place except when it is 

 well up towards the olecranon or its tuberosity, the upper seg- 

 ment of the bone being in that case likely to be drawn upward. 

 For a simple fracture of this region there exists a fair chance of 

 recovery, but in a case of the compound and comminuted class 

 there is less ground for a favorable prognosis, especially if the 

 elbow joint has suffered injury. A fracture of the cubitus alone 

 is not of serious importance, except when the same conditions 

 prevail. A fracture of the olecranon is less amenable to treat- 

 ment, and promises little better than a ligamentous union. 



Considering all the various conditions involving the nature and 

 extent of these lesions, the position and direction of the bones 

 of the forearm are such as to render the chances for recovery from 

 fracture as among the best. The reduction, by extension and
