    Where the frog is in a morbid ftate, and unnaturally deprived of perpendicular preffure, it is feldom fate to lower the heels at once, fo as to make the frog on a level with the Ihoe; and, in many cafes, it is not pofiible with any fhoes, or .even without {hoes, to give the frog preffure on fmooth furfaces; much lefs is it practicable for the frog to reft on the ground when fhod with common thick- heeled {hoes. In the {table, therefore, while at reft, the frog is generally railed above the ftioe, and as preffure is effential to its health, particularly when the hoof is expofed to heat, it appeared to me of great importance, in all cafes where the heels of the ftioe and the fro^ cannot with fafety be made on the fame level, to apply an artificial frog, to fit and give any degree of preffure, in the liable, to the natural frog, with any {hoes. With that view, I firft employed plaifter of Paris, but from its tender texture, that application was found to fail, and Mr. Ridfcvord, a very intelligent pupil of the college, propofed to employ leather, and to. conned! it with the ftioe by firings. This plan alfo did not fucceed, but I think it a duty due to Mr. Riclfword, to mention, that in the con- ftrudtion of the artificial frog, I have received confidcrable afiiftance from his attention and ingenuity.
