Magner's ABC guide to sensible horseshoeing : a simple and practical treatise on the art of shoeing horses . indit perforated everywhere by myriads of mi-nute apertures, which look as if they had beenformed by the point of a fine needle. If welook also at the vascular parts of the foot thathave been in contact with this horny surface,it will be observed that they have been closelystudded with exceedingly fine, yet somewhatlong, filaments, as thickly set as a pile of therichest Genoa velvet. These are the villi, orpapillas, which enter the horny cavity, andfitting into them like so many fingers into aglove, constitute the secretory apparatus ofthe frog as well as the sole. Each of thefilaments forms a horn tube or fibre, and pass-es to a certain depth in a protecting canalwhose corneous wall it builds. When injectedwith some colored preparation, one of themmakes a beautiful microscopical object, appearing as a long, tapering net-work oiblood-vessels, surrounding one or two parent trunks, and communicating with eachother in a most wonderful manner. These filaments are also organs of tact, each. Fig. 585.—Shoe for Quarter-crack. 74 CAUSES OF INJURY. containing a sensitive nerve, destined to endow the foot with the attributes of a tactile organ. This distribution will enable us to realize, to some extent, the amount of in-jury done by paring. The horn thrown out for their defense and support being re-moved by the farriers knife, and perhaps the ends of these villi cut through, themeager pellicle remaining rapidly shrivels up, the containing cavity of each vas-cular tuft as quickly contracts on thevessels and nerves, which, in their turn,diminish in volume, disappear, or be-come morbidly sensitive, through thissqueezing influence. The feet of a horseso treated are always hot, the soles aredry and stony, and become unnaturallyconcave. The animal goes tender aftereach shoeing, and it is not until the hornhas been regenerated to a certain ex-tent, that he steps with anyth
