In thepresent case it stands only apparently in contradiction with theidea of the cell as the elementary individual; for by the cutting-operation there are obtained, not new stages of individuality, butcomplete Stentors, , individuals of the value of a cell. In allsuch divisions of cells, wherever protoplasm and nucleus are presentin the pieces, the latter have the value of cells; in the process wedo not go below the cell. If, howrever, the cut be made so thatone piece contains protoplasm and nucleus, and the other onlyprotoplasm, the former continues to live and represents a completecell, while the latter, possessing no longer the individuality of
