And as the firft flioot of the cruft at the coronet is very thin, the dire&ion of its fibres will be altogether re- gulated by the width of the cartilages immedi- ately below the hair at the quarters and heels, and the cartilages will be always more or lefs expanded, and the hoof more or lefs circular, as the frog has more or lefs preflure. On that principle I long fince recom- mended a flioe with thin heels, as the beft formed flioe to bring the frog on the fame level; and with great truth I can affert, that, although in fome inftances, from a fudden mif- application of the thin heel’d fhoe to improper feet, I have feen the tendons afte-Sted, yet from all the experience I have fince had, and from all that I have feen or heard of the prac- tice of others, I know of no inftance where the frog, from conftant preflure, <fid not ex- pand
