Thechromatin-staining lobes within the leucocytes are there-fore not nuclei but centrosomes, and the so-calledAltmanns granules, which have been variously sur-mised to be collections of food or secretion, are theelements of the chromosomes As inlymphocytes so in leucocytes, the chromosomes areoutside the nucleus. Divisions have been induced inhundreds of leucocytes, and the procedure is alwaysthe same in all of them (figs. 79-86). Now, the increased quantity of the azur dye con-tained in the jelly did not improve the mitosis inducedin the lymphocytes; in fa
