TREATMENT.—In the more severe cases, the shoes should be removed from the feet, and the hoof pared down until the horn yields to the pressure of the thumb. Give the horse rest, and allow him to lie down, wrap the hoofs in cloths soaked in water, and renew them from time to time. If the disease is from the feet having been battered by long driving or riding, bathing them with HUMPHREYS’ MARVEL WITCH HAZEL will be of great value. In some cases, a cold poultice, made of mashed turnips or carrots, is of excellent service. The remedy is B.B., of which a dose may be given every three hours, in acute cases. In recent cases, when there is _fever_, _decided lameness_ and _heat of the foot_, and indeed in almost every case, you may better begin with A.A., of which give a dose every two hours, and after three or four doses, alternate with B.B., as often as every two hours, and after the force of the disease has abated, the B.B., may be continued alone at increasing intervals, until entire restoration. When the disease is clearly traceable to _over-feeding_, the B.B. and J.K., may be alternated from the first, every three or four hours, in doses of fifteen drops. In case of chronic founder, the B.B. should be given, a dose of fifteen drops, each morning and night, and the treatment continued for some time. An occasional dose of J.K. will be useful as a constitutional intercurrent remedy, and may be given at noon, while the B.B. is given morning and night. On the Formation of Joints Joints are formed of bones which fit into each other by unequal surfaces, whose cavities and eminences mutually correspond. As the roughness of the bones would prevent their moving freely without friction, we find an intervening smooth elastic substance called cartilage, which not only obviates this inconvenience, but in a great measure takes off the jar that would otherwise ensue when the horse moves on hard ground. To render the motion still easier, we find the cartilage covered with a fine synovial membrane, secreting a fluid of an albuminous and oily character, which acts in the same capacity as oil to machinery, namely, to prevent friction. Besides the membranous connection of bones which enter into the formation of joints, there are strong, flexible substances of a fibrous texture called ligaments, which are the chief bond of attachment, and support the lower joints; while others are further strengthened by muscles and tendons. Bursæ mucosæ are small closed sacs which surround the tendons wherever there is friction; they are analogous in structure to the synovial membrane, and secrete a similar fluid. Synovitis
