2. In the Porcupine, the fl. dig. long, and fl. hall. long. 

 pass round separate grooves on the inner ankle, and unite in 

 the sole of the foot, to give origin to tendons distributed to 

 the five toes, as shown in Fig. 15. 

 The relative cross sections of the ten- 

 dons are as follows, and differ from 

 those previously found for other ani- 

 mals, by the flexor tendons of the 

 muscles being in excess of the flexors 

 of the toes, as in the case of the Rhi- 

 noceros.
