'THE Aisr ATOMY OF THE INDIAN ELEPHANT. IS 



arises, close to the common tendon, from the internal condyle of 

 the humerus, but somewhat deeper. It lies 'henesAh flexor com- 

 munis digitorum, and to its radial side. At the lower fourth of 

 the fore-arm it ends in a round tendon, which joins the deep 

 surface of the common flexor. Another muscle arises by fleshy 

 fibres from the ulna, beneath the ulnar origin of flexor carpi 

 ulnaris, and to its inner side. It consists of a small conical 

 bundle of muscular fibres, ending in a thin round tendon near 

 the upper extremity of the fore-arm. The tendon joins the deep 

 surface of the tendon of the common flexor on its ulnar side.

Flexor hrevis digitorum arises from the annular ligament of the 

 wrist, where it forms a sheath for fl,exor carpi radialis. It con- 

 sists mainly of fleshy fibres. Opposite the base of the radial 

 sesamoid it divides into two nearly equal masses, of which that 

 to the radial side is inserted into the sheath of the long flexor 

 tendon of the 4th digit. The short flexor crosses the other 

 superficially, and is attached to its ulnar side. The second mass, 

 shorter and smaller than the other, is similarly inserted into the 

 flexor tendon of the 5th digit, blending also with the palmar 

 fascia at its attachment to the sesamoid bone of the 5th digit.

Extensor carpi radialis longior (supinator longus?) arises 

 chiefly from the lower part of the tendon of insertion of the 

 deltoid on its outer side. It extends a little further upwards, 

 and is connected with the lower and anterior border of the ex- 

 ternal head of the triceps. Between these points a thin slip 

 arises from the humerus. The muscle passes down in its usual 

 position, bridging over the brachialis anticus. It ends at the 

 lower third of the fore-arm in a small tendon, which passes 

 together with extensor carpi radialis beneath extensor proprius 

 poinds, then through a sheath upon the radius, having a separate 

 compartment, but lying in the same groove with extensor carpi 

 radialis. It lies rather deeper than that muscle, and to its inner 

 side. It is inserted iato the semilunar bone of the carpus.

Extensor carpi radialis hrevior arises from the front of the 

 external condyloid ridge. It ends in a strong tendon which
