pair, which generally retain their ordinary position and form, 
although frequently showing a more or less pronounced lack 
of symmetry. When the Zoological Society possessed a 
farm at Kingston Hill, in the year 1829, several of these 
four-horned sheep were kept there; but, although llamas 
and alpacas, which are just as much domesticated animals, 
are exhibited at the present day in the Society’s menagerie 
in the Regent’s Park, four-horned and other abnormal 
breeds of sheep are not on show. Flocks of four-horned 
sheep are, however, kept in several British parks. 
Bearing in mind the close affinity existing between 
sheep and goats, it is not a little remarkable that the 
additional horns developed in the four-horned breed of the 
former should approximate to a considerable degree both 
in direction and in curvature to those of the latter. This, 
however, must not be taken as an indication that the 
additional pair in the four-horned sheep represents the 
normal pair of the goats. 
Four-horned sheep belong to at least two distinct breeds, 
one of which is of great antiquity. According to report this 
breed originally came from Iceland and the Faroe Islands, 
where these sheep still exist, as they also do in the Orkneys, 
Shetlands, Hebrides, and the Isle of Man. Occasionally, it 
is said, the little brown sheep of the island of Soa, in the 
Hebrides, develop four horns, although they are normally 
two-horned. 
Like the Soa breed, European four-horned sheep are 
of very small size, and dark in colour, the fleece being not 
infrequently mottled with patches of brown and white. The 
wool, too, as in nearly or quite all the inferior breeds of 
sheep, is much mixed with hair, so that it is by no means 
of a fine quality.
