Tactile cells (Merkel). Tactile cells, isolated or in groups, but in the lattercase not collected together to form a tactile end-organ, are described by Merkelas occurring in the deeper layers of the epidermis and sometimes in the sub-jacent true skin over almost the whole of the body. In animals they are. 1C2 NERVOUS SYSTEM. especially numerous in parts of the skin whicli are devoid of hairs, as in thatwhich covers the soles of the feet, and on the snout, as well as amongst theepithelium-cells of the hard palate. The cells in question are round or pyriformin shape, and prolonged at one part into the axis-cylinder of a nerve-fibre : incases where the axis-cylinder is ramified, it may be connected with more thanone of these cells. Each cell is stated to be inclosed by a cell-membrane whichis continuous with a prolongation of the primitive sheath of the the tactile cells occur in the superficial layers of the cutis vera instead of amongst the cells of the epidermis they are foundy. ..^„ to be inclosed in a capsule of connective tissue, ° ? which is pierced by the axis-cylinder of the nerve- fibre as this passes to ai:)ply itself to one of thesurfaces of the usually flattened cell.
