The arrangement of the flexor tendons in the foot of the 

 Rhinoceros differs from that of any of the animals already de- 

 scribed — for the total strength of the tendons of the toes is 

 20-J per cent, short of that of the tendons of the muscles, in- 

 stead of exceeding it, as in the former cases. 



If we consider, however, only the deep tendons of the 

 toes, and tendon of the long flexors, as in the former cases, 

 neglecting the plantaris and short flexor, and perforate ten- 

 dons of the toes, we find a result similar to those already re- 

 corded, viz., counting the total cross section of the long flexors 

 of the toes as 100 : — ■
