From these and similar observations, Haberlandt and Korscheltdraw the following conclusions, respecting the function of thecell-nucleus :—- 1. The fact that the nucleus is grenerallv found in a definiteposition in the immature and developing cells, indicates that itsfunction is connected chiefly with the developmental p
