| In fact, the infusorian simply swallows whatever happens to hit his mouth. |
| The infusorian can be called potentially immortal, because of this method of reproduction. |
| This has been shown by the careful experiments of Maupas, who had observed 215 generations of an infusorian without sexual union. |
| Thus the plant, that seems to know two things, is twice as well off as the infusorian that knows only one. |
| The exchange of life-elements between two individuals is well illustrated in the case of the infusorian Noctiluca. |
| So far as we can see, therefore, everything that the infusorian feels at all, feels to him exactly like everything else. |
