ANATOMY OF VERTE CRATES.

fibres directly from the radius, and its tendon is shorter and much 



thicker than in Man. 

 In both it passes 

 through a pulley pro- 

 vided by the trapezium 

 to its insertion into the 

 base of the metacarpal 

 of the index. The 

 tendon of the supina- 

 tor longus in the Go- 

 rilla, fig. 24, 4', is also 

 shorter and thicker, 

 and is not crossed, as 

 in Man, by the exten- 

 sors of the metacarpal 

 and first phalanx of 

 the pollex (fig. 23, n 

 and 12) before its in- 

 sertion into the styloid 

 process of the radius. 

 Part of the carneous 

 mass of the flexor sub- 

 limis dis;itorum is seen 



o 



at is, fig. 23, and o', 

 fig. 24. External to 

 this a greater pro- 

 portion of the flexor 

 profundus appears in 

 the Gorilla, fig. 24, 6, 

 than in Man, fig. 23, 

 15. The flexor longus 

 pollicis, fig. 23, 14, ex- 

 pends its force in the 

 Gorilla, fig. 24, 20, 

 upon both the pollex 

 and index, furnishing 

 tendons to the distal 

 phalanx of each, but 

 the largest and most 

 direct beino; that to the 



o 



index. There are mo-
