and becomes united radially with the thick flat 

 tendon ending the first two heads. The common 

 terminal tendon splits into four points which pass 

 among the tendons of the carpo-phalangei muscle 

 and are inserted on the terminal phalanges. From 

 the terminal tendons of this muscle spring the 

 lumbricales muscles. 



Carpo-phalangeus (Plate II., Fig. I, 8} (Ab- 

 ductor pollicis) . Springs from the os carpi-radiale ; 

 is inserted on the first phalanx of the thumb. 



Car po-metacar palls I. (Plate II., Fig. I, p) 

 (Opponens pollicis). Originates from the os carpi- 

 radiale and is inserted on the radial side of the 

 entire first metacarpus. 



Metacarpo-phalangeus I. Originates from the 

 base of the metacarpus of digit III. ; is inserted on 

 the ulnar side of the first phalanx of the thumb. 



Pisiformi-phalangeus primus digiti V. (Plate II.,

 petit doigt, Abductor digiti quinti). Springs from 

 the pisiform bone, and is inserted on the medial 

 border of the first phalanx of the fifth finger. 



Car po-metacar palls V. (Opponens digiti minimi, 

 Opponens primus). Springs from the carpi-ulnare

 fifth digit. 



Carpo-phalangeus primus digiti V. (Plate II., 

 Fig. i, j) (Flexor digiti minimi brevis, Opponens 

 secundus). Arises from the ulnar border of the 

 proximal part of the carpi-radiale bone and is
