CHAPTER XXVI 



THE UNGULATES continued 



TAPIRS, RHINOCEROSES, AND HORSES 



WITH the three groups of animals known as tapirs, rhinoceroses, and horses, we 

 come to an assemblage of Ungulates differing in many important respects from all 

 those described in the preceding chapters, and collectively constituting a distinct

primary divison of the order to which they belong. The most obvious external 

 characteristics of this assemblage of animals are displayed by their feet, in which, as 

 we have already had occasion to mention (p. 743), the toe corresponding to the 

 third or middle finger of the human hand, or to the middle toe of the human foot, 

 is always larger than either of the others, and is symmetrical in itself. This pecul- 

 iarity of foot structure is exhibited in the accompanying figure, and likewise in the 

 illustration on p. 1042; and how essentially different it is from the type of foot 

 obtaining in the Even-Toed Ungulates will be apparent by contrasting these figures 

 with the illustration of the foot of the pig given on p. 1009. In all the Even-Toed 

 Ungulates, we may once again remind our readers, instead of the third toe being 

 symmetrical in itself and larger than either of the others, it is symmetrical to a line 

 drawn between itself and the fourth toe, and is equal in size to the latter, with 

 which it forms a pair.
