other. The whole structure, together with the angle 

 of the pastern, ensures that elasticity which is so 

 necessary for the animal's welfare. 



In order that these bones may be the better im- 

 pressed upon the mind, I strongly recommend the 

 reader to colour the figure, just as maps are coloured, 

 for the purpose of making them more easily intelli- 

 gible. My own figure is coloured as follows : 



Taking the same order as has been observed in 

 the description, the skull is olive-green, and the 

 lower jaw blackish-grey. The cervical vertebrae are 

 yellow ochre, the dorsal vertebras blue, the lumbar 

 vertebras red, the sacrum brown, and the tail red. 



The true ribs are olive-green, and the false ribs 

 purple. As for the limbs, the scapula and pelvis 

 are pink, and the humerus and femur olive-green. 

 The radius and tibia are yellow ochre, while the 

 ulna and fibula are red. The carpus and tarsus are 

 brown, the metacarpals and metatarsals purple, the 

 splint bones scarlet, and the phalanges brown. Of 

 course, the darkened bones of the right limbs should 

 be left uncoloured.
