134 PROCEEDINGS OF THE ANATOMICAL AND ANTHROPOLOGICAL 



RECORD OF ANATOMICAL VARIATIONS. 



Date of observation, February, 1904. 

 Sex, female. 



Abnormal insertion of pectoral is minor muscle (left}. 

 In this case the tendon of insertion passes over the coracoid 

 process nearer the inner extremity of the horizontal portion, and 

 piercing the coraco-acromial ligament, is inserted into the capsular 

 ligament of the shoulder joint below the tendon of the supra spinatus 

 muscle. 



On the right side it was quite normal.

Date of observation, February, 1904. 

 Sex, male. 



Abnormal bruchial artery (left). 



In this case the brachial artery divided about 2 inches from its 

 origin into two branches, superficial and deep. The deep branch lay 

 behind the median nerve as far as the elbow. About 2^ inches above 

 the elbow and to the internal border of the anterior surface of the 

 shaft of humerus there was a slight ridge, a rudimentary supra- 

 condyloid process. From this ridge a ligamentous band crossed over 

 the median nerve and deep brachial artery, and passing obliquely 

 down and inwards, blended with the internal intermuscular septum 

 and the fascia covering the origin of the pronator radii teres. 



On the right side the artery was quite normal.

 Sex, female. 



Abnormal brachial artery. 



Ill this case the artery extends down the arm as a single vessel 

 as far as the middle of insertion of the coraco brachialis, where it 

 divides into two equally sized branches. The median nerve on its
