It is not difficult to follow this transformation through its successive stages, and thus to arrive satisfactorily at the im- portant physiological fact of the individuality of the cells. It is only necessary first to examine the stem or any other organ in the embryonic condition, and then at intervals, soon after active life has begun to manifest itself in the germ. If we observe the fibrous portion of the wood, for instance, when germination commences, we shall see that at first the fibre cells consist of a row of utricles somewhat more elongated than the neighboring cells; gradually these.
