    EXPLANATION OF THE PLATES. PLATE I. Fig. 1. Zeiss system E. Ocular 2. Swarming Micrococcus of small-]Dox. Fig. 2. Zeiss F.2. Cryptococcus forming in twenty-four liours from tlie Micrococcus of small-pox raised on glycerine, under an liermetically sealed bell-glass. Fig-. 3. Z. F.2. Mycothrix chains from the small-pox. In the links of the chain is seen a dark nucleus. Fig. 4. Z. F.2. Swarming Micrococcus from sheep-pock, here and there Mycothrix chains, with a nucleus in each joint (k). Fig. 5. Z. F.2. Quiet Micrococcus from the Munich kine-pock fluid. Fig. 6. Z. F.2. Micrococcus from the sheep-pock, cultivated on sugared water. The Micrococcus cells are for the greater part grown to short Leptothrix or Mycothrix chains. Bacteria (auct). Fig. 7. Z. F.2. The same culture. At the edge of the liquid and at the bottom of the vessel, the Micrococcus cells slowly swelhng to large clear sporoids, ready to sprout, with one or more nuclei, after culture of fourteen days. Fig. 8. Z. F.2. The same culture. The large round cells (Spo- roids), which swim in the liquid, discharge their nuclei, which were formed from a plasm investing the wall. Fig. 9. A sprout of Sporoid (Fig. 7), bearing in every branching thread a chain of at first oval, at last round spores, which become pale in the fluid and discharge their contents (Fig. 8). Fig. 10. End of some sprouts at the brim of the vessel. At every termination is a chain of brown spores. There lay thrown out spores partly roundish, partly cladospore-like Septate (c I), partly very large and pale bodies (hi), scattered in the fluid. Fig. 11. Sprouts from the Micrococcus of Sporoids, germinating on the white of an egg. The spores were drawn out in an irregu- larly branched pencil. Fig. 12. Micrococcus of sheep-pock, slowly swelling to cells able to sprout (Sporoids), which already, here and there, have put forth long shining Oidium-like sprouts.
