...biologist could look at a fertilized human egg-cell under a super-powerful microscope, and study it under all sorts of conditions without removing it from the body that contained it, he might be able to tell whether that cell would become a still-born child or one that would live to ripe age. The biologist cannot do that, but he is learning more & more about the nature of cells, and with each new bit of cell knowledge comes new knowledge of the nature of human beings, who are just cells multiplied and grown up. Last spring Dr. Francis Ferdinand...
...Cell (protoplasm), biologists agree, is made up of two main parts: the yolk-like nucleus and the oily cytoplasm. Both nucleus and cytoplasm contain solid and liquid portions; in addition they contain further specialized units of matter: in the nucleus, membrane, nucleolus, chromosomes; in the cytoplasm, membrane, granules, vacuoles, plastids. It is the behavior of these infinitesimal units that biologists are now trying to study...
...metal mounted as a head on a centrifuge axis. Into one end of the bar is built a microscope-objective (the lower lens, system of a microscope). Above this objective is an aperture in the bar, and directly over the aperture is a light. The light illuminates a cell placed on a slide in the aperture. By an arrangement of prisms placed periscope-wise in the bar, the image of the cell is carried through the microscope-objective, to one prism, then to the other, then through the upper lens of the microscope to the eyepiece, which is directly above...
Scientists Harvey & Loomis watched cells whirl, saw the tiny granules moving through the protoplasm, oil globules going in one direction, yolk granules in another. From the rate of movement they began to calculate the viscosity (gumminess) of the protoplasm. When oil and yolk are separated they exert a pull upon the cell which divides it in two parts. By watching the course of that process the experimenters were able to estimate the tension on the surface of the cell which holds it together. That tension, they found, is at least 100 times smaller than had been supposed. Preliminary results...
