    these bodies were grouped in a manner similar to the arrangement of the glomeruli in the spleen, but much closer together. The structure of these bodies differs. The smaller ones consist simply of a collection of small spheroidal or polyhedral cells, closely packed together, without demon¬ strable intercellular substance, and closely surrounding a small artery, the whole being sharply ontlined against the surrounding tissue. Such a structure is represented in Fig. 2. Then there are somewhat larger bodies Fig, 2. Fig. 3. whicli have the same general appearance, but which have a well-marked r underlying reticulum of fine anastomosing fibres. The meshes of this ^ reticulum are filled with cells : those near the periphery being small, sphe¬ roidal, or slightly polyhedral, resembling leucocytes, and very closely packed together; while the central meshes are occupied by larger j3oly- hedral cells with large nuclei. These structures are usually well supplied with capillary bloodvessels, Fig. 3. Then still another variety of these bodies is seen, especially near the junction of the tumour proper with the parotid gland, having the same : general appearance to the naked eye and bearing the same relation to the bloodvessels. They have a ! delicate underlying reticu- ! lum, whose meshes are filled 1 with cells similar to those [ occupying the central por- ; tions of the last described I bodies. But scattered here I and there within them, some- j times few in number and j again very abundant, are i seen tubular structures hav- I ing a thin membrana propria land lined with cylindrical or cuboidal or polyhedral cells. Those lined with cylindrical land cuboidal cells have usu¬ ally a well-defined lumen. Fig. 4. 1 -while those lined with poly- I
