together the whole way and had the same relations to the surrounding parts. 

 They arose from the right kidney one above the other, while the line joining 

 their bladder orifices was vertical in direction and rather under half an inch 

 in length, the upper of these two openings corresponding with the one on 

 the opposite side. The internal channel of the lower ureter was consider- 

 ably narrower than that of either of the other two.

Date of observation, November, 1909. 

 Sex of subject, Male. 



I. (a) Abnormal origin of dorsalis scapulae. The dorsalis scapulae 

 artery of the right arm in this dissection came off the brachial artery, behind, 

 and on the same level as the posterior circumflex artery about If in. below 

 the middle subscapular. 



(b) High division of the brachial artery. The artery divided into two 

 large branches radial and ulnar at the insertion of the coraco brachialis 

 muscle. The radial branch lay anterior to the ulnar, and crossed over the 

 latter about 3 in. above the base of the antecubital foosa. 



The superior profunda artery was normal, but the inferior profunda came 

 off the ulnar, | in. below the bifurcation of the brachial. The anastomotica 

 magna artery came off the ulnar artery 2 in. below the inferior profunda. 



II. (a) Abnormal insertion of extensor minimi digiti. The tendon of 

 this muscle divided in its synovial sheath, under the annular ligament (post.) 

 into two slips. One, normal, went to the base of the dorsal surface of the first 

 phalynx of the first finger; the other, abnormal, was inserted into the dorsal 

 surface of the first phalynx of the ring finger. 



(b) Flexor carpi ulnaris. The tendon of this muscle gave off a slip under 

 the anterior annular ligament to blend with the sheath on the dorsal surface 

 of the metacarpo-phalangeal joint of the little finger. 



(c) Third head to biceps muscle. A third head was found in this 

 dissection, and has been described by the dissector of the left upper extremity, 

 where a corresponding third head also existed.
