The sequence of events in mitosis is commonly divided into four main phases, namely, prophase, metaphase, anaphase (Strasburger, 1884) and telophase (Heidenhain, 1894). It must not be forgotten, however, that these are arbitrary divisions of a continuous process. The prophase consists essentially in the reconstruction of the chromatin and Unin of the resting nucleus into filaments, which by a process of.
