Excerpt from book: the wall and there will appear two germs where formerly only one was visible. There are anthrospore and endospore forms of bacteria. The endospore bacteria form their spores on the inside of the plasma or wall of the cell, while the anthrospore bacteria do not. The zoogloea forms of bacteria are peculiar to slimy formations, so that when you observe any fluid of a ropy nature, as sometimes happens with peas, it is this form of bacteria largely the cause of such action, but there are of course other reasons for ropiness in canned peas. These bacteria grow very fast in colonies almost pure naturally. The spore formation of the yeast plant, saccharomyces, is most interesting. The view of these cells budding as seen under a power of 1000 diameters in the microscope, is most interesting because they can be seen so plainly, and their appearance is beautiful. In fact the microscope opens up a new world in the vegetable kingdom and the study is most fascinating. Figure 3. i took a quantity of filtered tomato juice and placed a culture of these alcohol ferments in it, and the next day I transferred a single drop under the cover glass, filling the slight excavation and laying the cover glass over this to prevent to a certain extent the evaporation of the liquid. I located a few cells and watched them closely; I detected shining spots within the cell walls which appeared to be swelling. After a time I was awarded by seeing a slight protuberance on one side of a cell which increased rapidly in size, remaining attached to the parent cell. After a time other cells began budding, and then I noticed that the first bud had fully developed and was in its turn showing signs of germination. In a short time it sent out a bud and the mother sent out another one in the opposite direction. In...
