THE GAZELLES AND THEIR ALLIES 617 
was shot near the headwaters of the Amala River, close to 
the German border, by Heller. The average horn length 
in this large series is 24 inches. The record horn length for 
British East Africa, given by Ward, is 31^ inches, while 
that for the typical race of South Africa is 27^ inches. 
The difference in these lengths represents fairly well the 
amount of difference in size of the two races. Specimens 
measuring 27 yi inches are not at all rare in British East 
Africa. 
In Millais’s delightful “ Breath from the Veldt,” a book 
which illustrates well why photographs can never approach 
in value true pictures of wild life by a competent nature 
artist, a special study is made of the springbuck. This 
South African gazelle is shown in all its extraordinary leap¬ 
ing postures. There are also pictures of the impalla, but 
not in its characteristic attitudes. It is a pity that Millais 
did not do for the impalla what he did so well for the spring¬ 
buck and for that most eccentric of four-footed beasts, the 
white-tailed gnu. Among all the horned animals of middle 
Africa the impalla is the one which when alarmed takes the 
most extraordinary leaps and bounds. When a herd is 
frightened in fairly thick but low bush, the animals go off 
almost like birds, springing in every direction, clear over 
the bushes, or many feet into the air even when there are 
no bushes. Their carriage is beautiful, their movements 
are the perfection of grace and agility. Their annulated 
horns describe each a spiral, and their beautifully colored 
coats, contrasted red and white, have a satin sheen. Their 
coloring makes them very conspicuous, as it contrasts 
sharply with all their usual surroundings. The buck, when 
amorous, displays the coloration by strutting among the 
does with tail erect and the hair of the rump and sides
