the hallux at an angle of 24 0 . The four branches of the long 

 flexor tendon are distributed to the second, third, fourth } 

 and fifth toes ; that which goes to the 

 second toe uniting with the lesser branch 

 of the hallux tendon to form the flexor of 

 the second toe. 



This arrangement, which is subject to 

 many variations, is shown in Fig. 4, which 

 represents the tendons seen from below, 

 in the sole of the foot, but displaced from 

 their natural positions in order to exhibit 

 their mechanical arrangement. 



Example, No. 1 . — In order to obtain the 

 relative strengths of the various tendons, 

 I weighed equal lengths of those tendons, 

 with the following results : 3 p ig 4 



In the sole of foot. 



Flexor hallucis longus, 27 



Flexor digitorum longus, 26 



Total, . . 53 



In the toes. 



1. First toe, 27 



2. Second toe, 10 



3. Third toe, 12 



4. Fourth toe, 



5. Fifth toe, 8J 



Total, . . 66 



It will be observed that the sum of the cross sections of 

 the tendons actually distributed to the toes exceeds the
