The problem of age, growth, and death; a study of cytomorphosis, based on lectures at the Lowell Institute, March 1907 . Fig. 67. Stentor. the next of our slides, which represents a creature ofthe kind called Stentor, Fig. 67. It is a single nucleus of the cell has a singular form, for it con-sists of nine bead-like enlargements, with the partsbetween constricted to mere delicate connecting 200 AGE, GROWTH, AND DEATH threads ; its protoplasmic body is large, and some-thing of its structure I have told you in a previouslecture. A German investigator, Professor Gruber,has succeeded in dividing one of these Sten-tors, a unicellular creature, animalcule, common infresh water, into three parts, in such a method ofcutting as is illustrated by the figure on the of the three parts restored itself and became acomplete Stentor. In such experiments the proto-plasm around the nucleus begins to grow ; graduallythe original form is again assumed ; the creaturegrows larger and larger, until each piece acquiresthe parent size, and, so far as we can see withthe ordinary microscopic examination, identi
