90 THE PRI^XIPLES OF MYODYNAMICS. 



(5.) The long axis of the humerus met the 

 plane of the base of the head of the humerus at 

 an angle of about 45 degrees. 



83. In the same case, the following observa- 

 tions were made : 



(a.) The external condyle and the greater 

 tuberosity of the humerus pointed in the same 

 direction. 



(b.) The internal condyle pointed in the same 

 direction as a line on the head of the humerus 

 midway between the neck behind and the bi- 

 cipital grove in front. 



(c.) The greatest conjugate diameter of the 

 glenoid cavity of the scapula was about one and 

 one-fourth inches ; while the orreatest transverse 

 diameter was about one and five-eiehths inches. 



(d.) The acromion projected about two inches 

 bevond the Qflenoid cavitv. 



(e.) The coracoid process of the scapula pro- 

 jected somewhat above and in front of the glen- 

 oid cavit}". 



(f) The strong coraco - acromial ligament 

 completed the roof over the upper end of the 

 humerus.
