The general signs of age, unconnected with the animal’s teeth, are easily distinguishable. The head grows lean and fine; the features look more striking; the hollows over the eyes deeper; the eyes themselves grow irritable, and twinkle; the cheeks become lank; the gums and soft palate pale and shrunk; the sub-maxillary space is capacious; and grey hairs make their appearance in various places, more particularly over the eyes and about the face. In regard to the body generally, it also makes a more striking display of its shapes, than in any former part of life; the neck grows thin and fine; the withers grow sharp, and give an appearance of increased length and obliquity to the shoulder; the back sinks; the quarters assume a more blood-like turn, and seem to lengthen; tumors of all kinds, spavins, splents, windgalls, &c. generally become in part or wholly absorbed; the legs feel sinewy and free from puff, though they may evince instability and weakness. Now-a-days it is not often that we meet with horses thus advanced in years; still more rarely with any that have grown decrepit from age. * * * * * The horse, if properly treated, will live to a great age. The best time of his life is considered to be betwixt that of five and ten years, although there have been instances where he has proved highly serviceable until twenty years; and it is on record, that some horses have wrought till upwards of thirty years old. Mares are said to be aged at seven years old, and horses at eight. * * * * *
