SKELETON OF THE PURE ARAB HORSE “NIME” 
The chief difference in the anatomy of the Arab from that of all other horses is that it has but fix 
lumbar vertebrae while all other families of the horse have six. This difference in structure probably 
explains why the Arab, though small in size, is capable of carrying great weight and possesses 
such marvelous endurance. ‘The sire and dam of Nime were only one generation from the desert. 
The skeleton, reproduced above, is now in the Museum of Natural History, New York. (Fig. 17.)
