was loose, and, supposing that some injury had been done to 
the animal, he immediately called for Mr. Bartlett, the s f 
perintendent of the garden, when, upon further examination,

was the first account published of this interesting fact. The 
account will be found in the Proceedings of the Zodlogieil f 
Society of London for 1865. 
For the last four years I have had an antelope under my 
own observation, and have watched carefully the process of : 
development of the horns. 
The antelope fawns are born in the spring, and when ait 
months old the horns first begin to develop. They contin

the cow and sheep there is a horn-core formed by a ; 
longation of the frontal bone, and oceupying about tw off, 
of the interior of the horn. When the horn drops 
horn-core is found covered with a thick skin, and 
with hair, the same as the face of the animal, with # 
portion of the tip having already begun to harden; this 
ing as a wedge, forces the horn off. |
