Fig. 5.—Skeleton of Persimmon, a 66-inch Thoroughbred.
Fig. 6.—Side view of skull of Eric, a 36·5-inch Shetland pony of the riding type.
Fig. 7.—Skull of a new-born foal of the Celtic or riding type.
Fig. 8.—Skull of a four-year-old Prjevalsky horse from Mongolia. In the foal the cranium is relatively large and the face decidedly dished; in the Sheltie the face is longer than in the foal, but less bent downwards on the cranium and less dished; in the Prjevalsky stallion the cranium is less globular, while the face is very long and, owing to the bulging outwards of the nasals, “Roman-nosed.” Though in some Shetland ponies the face is long, the wild horse now found in Mongolia seems to have contributed little to the making of the modern Sheltie.
