. Common diseases of farm animals. Veterinary medicine. DISEASES OF THE FOOT 161 bars is a wedge-sliaped mass of rather soft horny tissue that projects forward into the sole. This is the foot jjad or horiiy frog. It is divided into two lateral portions by a medium cleft. The coronary cushion projects into the upper border of the wall. It is covered with vascular papillse which secrete the horny fibres that form the wall. The vascular lamince are leaf- like projections, the sides of which are covered by secondary leaves. Honu/ laminar, arranged the same as vascular laminar, line the wall. These tAvo structures are so fir m 1 y united that it is impossible to tear them apart without destroying the tissue. The velvety tissue covers all of the inferior surface of the foot, with the exception of the bars. As the name indi- cates, its surface is covered liv vascular papillir that re- semble tlie ply on velvet. It is firmly united to the horny sole which it secretes. The lateral cartilages are attached to the posterior angles of the pedal bone. They are flattened from side to side, and the portion that projects above the coronary cushion may be felt by pressing on the skin that covers it. The plantar cushion is a wedge-shaped piece of tissue formed by interlacing connective-tissue fibres and fat. It is limited on each side by the lateral cartilages. Its inferior face is moulded to the frog. The bony core formed by the last bone of the digit and the coffin bone was described briefly with the other foot bones. A very important bursa, because it is so frequently inflamed in coffin-joint lameness, facilitates the gliding of the flexor tendon 11.
