Cells produced by the division of corresponding cells are numbered alike. (From Wells, Huxley and Wells, The Science of Life, London, 1929.) means of a fine hair, the fertilised egg of the newt can be con- stricted into the shape of a dumb-bell, in such a way that the zygote nucleus is confined to one side. This side will then undergo cleavage as the nucleus divides, while the other side of the dumb-bell will remain uncleaved. By releasing the ligature, the constriction can be relaxed, and one nucleusâany one, at randomâmay be allowed.
