60 PROCEEDINGS OF THE ANATOMICAL AND ANTHROPOLOGICAL 



Date of observation, 22nd November, 1909. 



Age of subject, about 65. 



Sex of subject, Male. 



Side or region of subject, Right Axillary. 



From latissimus dorsi a slip is given off. Its fibres run parallel to the 

 course of the slip, its colour is similar to that of latissimus dorsi, except 

 at its insertion, being there similar to the pale colour of the insertion of 

 the coraco brachialis. This slip is broader at its origin, it measures 1 inch 

 in breadth and tapers gradually towards its insertion, blending with the 

 tendon of the coraco brachialis, which is inserted to the acromion process. 

 The whole length of the slip from origin to insertion measures 3 inches, 

 and its tendon measures 2 inches, 1 of which runs with the tendon of 

 coraco brachialis towards its insertion and has | inch of a tendon of its own.

Sex of subject, Male. 



Side or region of subject, Both Sides. 



Accessory Head to Biceps Muscle. 



This accessory head arises from the upper part of the brachialis anticus, 

 the origin being continuous with the fibres of insertion of the coraco-brachialis. 

 This head passes down the arm and joins the common tendon of the biceps 

 about two inches from its insertion into the radius. The abnormality is 



present on each side.

 Date of observation, 9th December, 1910. 



Sex of subject, Male. 



Abnormal communication bctiveen Median and Ulnar Nerves. 

 The abnormality consists of a slip given off from the median nerve, at 

 the point where that nerve gives off the anterior interosseous. This slip passes 

 downwards and inwards, between the flexor sublimis and flexor profundus 

 digitorum, to unite with the ulnar nerve, being crossed in the latter part of 

 its course by the ulnar artery.
