tendons of the second and fifth toes (Fig. 5) ; while the flexor 

 digitorum longus supplies the whole tendons of the third and 

 fourth toes, and the remaining parts of 

 the tendons of the second and fifth toes. 



This arrangement is shown in the par- 

 tially displaced tendons of Fig. 5. 



The relative strengths of the several 

 tendons were found to be as follows : — 



1 . First toe, . 



2. Second toe, 



3. Third toe, . 



4. Fourth toe, 



5. Fifth toe, .

Example, No. 5. — In this case the flexor hallucis supplies 

 the first toe, the second toe, and part of the tendons of the third 

 and fourth toes ; while the flexor digitorum communis supplies 

 the remaining parts of the tendons of the third and fourth toes, 

 and the whole tendon of the fifth toe ; sending also a small 

 branch, previous to its own trifurcation, to the tendon proper 

 of the first toe. This arrangement of tendons is shown in 

 Fig. 6, and is a deviation from the human type, in which the 

 whole tendon of the first toe is usually supplied by a single 

 muscle, viz., the flexor hallucis longus.
