23. The supinator is a small muscle arising from outer condyle 

 of humerus to the inside of and above the common tendon ; it is 

 attached to upper surface of radius. 



24. The internal anconeus arises from internal condyle of humerus 

 below all the other muscles ; it spreads out in a fan-like manner to 

 be inserted on to the ulna superficial to (below) the attachment of 

 the brachialis interims. 



25. The brachialis internus is a broad, flat muscle arising from 

 the deep pit on the inside of the humerus ; it is inserted on to the 

 ulna close to the internal anconeus. 



26. The flexor digiti II. major arises by a moderately long tendon 

 from the inner condyle of humerus ; it is connected by flat tendinous 

 bands with the secondaries ; about an inch before the wrist it 

 divides into two tendons, one of which runs forward and is attached 

 to the internal tendon of the wrist ; the other, the main tendon of 

 insertion, passes round the wrist, and is inserted on to a considerable 

 portion of the inner anterior margin of the first phalanx of the 

 index ; during the latter part of its course the tendon of this muscle 

 is crossed by that of the 



27. Flexor digiti II. minor. — This muscle arises from the middle 

 portion of the radial margin of the ulna, commencing just in front 

 of the insertion of the brachialis internus, and extending as far 

 forward as the origin of the extensor internus ; its tendon passes 

 above that of the flexor major, and is inserted on the anterior edge 

 of the second phalanx of the index, close to its proximal end. 



28. The extensor internus manus arises from the distal half of the 

 ulna, commencing just after the attachment of flexor digiti II. minor ; 

 it is nearly twice the size of the latter ; its tendon passes round to 

 the extensor side of the wing, and is there inserted on to the anterior 

 upper edge of the thumb metacarpal. 



29. The extensor j>ollicis arises from distal half of ulnar margin of 

 radius superficial to origin of extensor indicts and from posterior half 

 of ulna and interosseous membrane ; it is inserted on to the extensor 

 margin of metacarpal below the extensor metacarpi radii. 



30. The extensor proprius indicis arises from the ulnar margin of 

 radius ; its tendon passes below that of extensor communis digi- 

 torum, and receives a short muscular slip from the wrist ; it is attached 

 to the extensor margin of the proximal end of the second phalanx 

 of the index. 



I have not dissected out the intrinsic muscles of the hand. 



Muscles of the Hind Limb. 



1. The sartorius arises only from the front end of the ilium ; its 

 insertion is on to the tibia just above the crural. 



2. The crurceus arises from nearly the whole of the inner side of 

 the femur ; it is inserted by a short tendon on to the head of the 

 tibia, below and to the inside of the insertion of the sartorius. 



3. The pectineus is a small delicate muscle arising from the lower 

 margiu of the ilium just beneath the origin of the gluteeus ; it passes
