    Fig. 9. Lymphatic space of the white matter of the spinal cord containing the rest of a cell nucleus. Fig. 10. Lymphatic space of the white matter containing rests of cells. Figs. 11 to 16. Formations derived from degenerated cells, found in the lymphatic spaces of the white matter between the nerve fibers. Fig. 17. Large macrophage containing a body, probably a rest of a degenerated cell. Fig. 18. Diplococcus found in the necrotic zone of the gray substance. Figs. 19 and 20. Large fonnation (size three or four times larger than a neuroglia cell) found in the infiltrated gray matter of the spinal cord; containing a number of polymorphic bodies of unknown origin. Fig. 21. Small round bodies, showing pyroniniphile reaction, found in the infiltrated zone of the gray matter (compare their size with that of the neuroglia cells). They are also probably the detritus of cells, showing changes in their histochemical com- position. Description of Plate II. All drawings with the exception of No. 8, which is taken from Mott (magnification 1,000 diameters) are drawn with the 1/12 oil imm. Zeiss and No. 12 comp, ocular. Fig. 1. Macrophage of the spinal fluid with many bodies (see description in text) probably rests of nuclei of the polymor- phonuclear leucocytes. The nuclei of the macrophage are nuclei of mononuclear cells (large lymphocytes). Regressive modi- fication of the nucleolus in the nucleus on right side.. (Toluidin blue.) Fig. 2. Macrophage with endothelial nuclei and an enormous number of degenerated nuclei (no vacuoles). (Toluidin blue.) Fig. 3. Macrophage with several vacuoles in which are contained some rests of degenerated nuclei, some of which (drawn with light shade) show the “ fuchsinophile reaction” with the Ehrlich triacid methods. No trace of the nuclei of the macrophage. (Ehrlich’s triacid.) Fig. 4. Macrophage of mononuclear origin with three degenerated rests of nuclei. (Unna—Pappenheim.) Fig. 5. Macrophage with three nuclei of endothelial origin and many bodies. (Unna—Pappenheim.) Fig. 6. Little macrophage of mononuclear origin with some “ pyro- ninophile” bodies (drawn clear) stained red and several other bodies stained green with methyl green. (Unna—Pappenheim.) Fig. 7. Large macrophage with vacuoles which contain some de- generated nuclei. (Ehrlich’s triacid.) Fig. 8. Leishman—Donovan bodies from the blood of the spleen
