I was unaDie to determine satisfactorily the absolute 

 strengths of the tendon of the accessorius muscle, and of that 

 .vhich retracts the pad of the foot, but I found that equal 

 lengths of these tendons had equal weights, so that they 

 mutually eliminate each other from the 

 Tables. 



2. The tendons of the sole of the foot 

 in the Jaguar are shown in Fig. 9, which 

 represents the pad-retractor (a) and accesso- 

 rius (a) tendons in their natural positions. 



The relative strengths of the tendons are 

 as follows : — 



Jaguar (long flexor tendons of toes). 



1. First toe, . . 30.9 per cent. 



2. Second toe, . 24.2 ,, 



3. Third toe, . . 23.3 



4. Fourth toe, . . 21.6 ,, 



5. Retractor of pad, . .
