Though to the naked eye the laminee appear simple, under magnification each surface of every lamina is found to carry secondary laminte which interdigitate with corresponding secondary ridges of the laminar matrix. The coronary border (margo occultus) of the wall gradually thins away, because of the presence of a groove into which the coronary Coronary border of the wall. ( I > „ 00 e. Limbns ungultu. _ ^-.

The groove is closely punctated with small holes into which the papillae of the matrix are received. The free border (margo liber) in the unshod animal comes into contact with the ground, and has a more or less ragged appearance due to destruction of the hoof by friction and attrition. The thickness of the border is greatest at the " toe" (about 10 mm.), and gradually becomes less towards the "heel," where it is barely half that of the " toe.'' The free border is connected with the margin of the sole of the hoof by a definite line of pale and relatively soft horn. The inflected part (pars inflecta, "bar") of the wall forms a gradually tapering ridge on the volar aspect of the digit, between the sole and the cuneus (" frog "). 2. The sole (solea ungulse) is a strong plate of horny tissue applied to the solar (volar) matrix, and indented by a deep triangular notch into which are fitted the inflected parts of the wall and the "; Speaking generally, therefore, the sole may be said to have a cr
