serts partly into the proximal phalanx, sending also a few fibres to 

 the extensor tendon at that point, and partly continues as a yellow 

 elastic cord to form the retractor ligament of that side. 



The relation of these long tendons to the retractor ligaments was 

 also more or less evident in the other digits, especially in the 4th of 

 one foot. On the outer side of that digit the long tendon, after giv- 

 ing a slip to the extensor system at the metatarso-phalangeal joint, 

 ran on to join the extensor tendon near its insertion, but before do- 

 ing this gave off a broad band which blended with the entire width 

 of the normal retractor ligament of that side. On the inner side the 

 long tendon joined the extensor, but some fibres immediately left it 

 again to become elastic and form the dorsal border of the retractor 

 ligament.
