 order, as Cuvier observes, (Rdgne An., nouv.ed., i. p.561,) that perch,

 observations on the effect which bending the leg- and ancle-joints 

 might have upon the toes : the latter, however, exhibited no corre- 

 sponding inflection. In perfect agreement with this is the obser- 

 vation that the Pelicans do not perch when they go to rest."
