EXTINCT ANIMALS 



" outgrowths " of the skull, the chief horns 

 (the median and the large pair, of which only 

 the left-hand one is visible in the photograph) 

 originate as separate bony pieces, which, after 

 growing for a time as distinct bones, join tightly 

 to the skull. Sir Harry Johnston shot the five- 

 horned giraffe in the great " reserve " or pro- 

 tected area formed by the crater of the extinct 

 volcano Mount Elgon — some five miles across — 

 in the British Central African Protectorate of 

 Uganda. In less than three weeks from the 

 day on which he shot these specimens he was in 

 London, and brought the skins and skulls of the 

 specimens to the Natural History Museum ! 

 Central Africa, under the equator, can now be 

 reached in that short space of time. 



In Miocene times there were other large ani- 

 mals allied to the giraffe, but without so great 

 a length of neck. The giraffe family have 

 double hoofs, like the cattle, sheep, antelopes and 

 deer, to which they are allied — not single or 

 triple hoofs, like the horse family. Besides their 

 peculiar and very primitive horns they have 

 another small but definite peculiarity. The outer- 

 most of the group of eight front teeth in the 

 lower jaw corresponds in position to the canine
