Fin;illy, slanting pavements are believed by some to favour the production of disease of this bqne. When lameness comes on gradually in a horse six or seven years old or more, and the animal points his foot in the stable, we have strong grounds- for suspecting commencing navicular disease. It is of importance to be able to recognise this affection in its early stages, before the disease becomes^ chronic ; for not unfrecjuently therapeutic measures may be taken to prevent the progress of the inflammation. This form of lameness, although usually affecting animals of six years old and upwards, is not very uncommon in- younger horses from three to four years old. When the disease first begins,- there may be but little to attract attention beyond the pointing of one or both fore feet in the stable, an abnormal warmth of the hoofs, and a scarcely perceptible lameness, perhaps only manifested at times, and disappearing after exercise. As the disease progresses, the lameness increases, and is more marked after rest; especially when this is preceded by a journey of seven or eight miles sharp trotting on hard ground. If the foot be examined, it is sometimes found to be hotter than normally, and as a result of the disease of the navicular bone it becomes contracted ; but it may be pointed out that contraction is not always present in navicular disease, nor is every contracted foot necessarily accompanied by this affection of the Contracted Foot. Unless the case be somewhat advanced, the animal generally walks sound ; but betrays his disease by his short groggy steps when trotted, especially when going at a sharp pace over hard stones. The horse digs his toes in the ground in order to obviate the pain, which would be caused by bringing the heels firmly do
