ANATOMY AND PHYSIOLOGY OF THE SKIN 31 of concentric, nucleated, vascular capsules, arranged after the mannerof the capsules of the onion, more closely united at the periphery thanat the centre, and surrounding a protoplasmic core. The medullatednerve to which the body is attached gradually loses its myeline envel-ope, and terminates in the centre of this core, after traversing the Fig. Section of a papilla still covered by a portion of the stratum mucosum and containing a tactilebody (from the skin of a finger). The corpuscle of Meissner is seen to consist of minute lobules,made up of a homogeneous protoplasm, with numerous oval nuclei and nervous fibrillse woundin a spiral direction about the mass of the corpuscle. The extension of the fibrillse to the mucouslayer is shown. The sources of the nerve-filaments are demonstrated to be: (1) the axis-cylindersof one or two double-contoured nerve-fibres, splitting into their original fibrillse on arriving at thecorpuscle, winding about the latter in characteristic spirals, and passing to the palisade-layer of theprickle-cells of the rete, between which, on account of the long prickles of the latter and the gen-eral resemblance of the two in thickness and contour, it is difficult to trace them further ; (2) fila-ments from another double-contoured nerve-fibre (h) pass directly to the inferior layer of cells inthe ret
