A careful examination of specimens which have been obtained for theparticular purpose of ascertaining what are the structural relations betweenthe callosities and the ergots of the horse tribe and the plantar and thepalmar pads in man and the dog has led to some very interesting results. The several parts referred to may, for convenience, be considered in thefiist place as they appear to the unaided eye of the ol)server. After whichtheir minute structure will be more easily explained. Man has no distinct pads beyond those which have been described ashardened cuticle, the result of pressure and of friction affecting certainprominent parts of the soles of the feet and the palms of the hands.

In the dog the palmarand the plantar pads areunderneath the fore-feetand the hind-feet B, fig.664. Two fatty cushionsform the bulk of eachpad, and the surface of theskin covering the cushionsis an extremely beautifulstructure, to which the useof the term hardened epi-dermic covering, althoughstrictly correct, certainlydoes very scant justice. Looking at the suifaceof any one of the padsunderneath the foot ofthe dog, when it is freedfrom the habitual coatingof dirt, the ol)server willbe struck by its tessellatedor che(;uered appearance.A series of columns oi-cones will be distinguished,with the points directed,in .th
