Excerpt
The refinement and applications of the experimental physical methods to cell physiology has made in the last decade an imposing progress. The micromanipulator, the centrifuge-microscope and other ingenious devices have brought to light and made even quantitatively measureable a number of such properties of the cell, about which in the best case only guesses could have been made before. We know now a great deal about the viscosity of the protoplasm and its changes during different phases of the life of the cell; we know the pH and the rH of the cytoplasm and even in some cases of the nucleus; we know a great deal about the electrical properties of the cell. And yet, in spite of all this progress, our knowledge of the fundamental and ultimate causes of one of the most important phenomena of the life of the cell, namely that of the multiplication, remains as unsatisfactory
