If certain propor-tions of alkaloid have been added to the jelly, theseamoeboid movements will be very marked (fig. 7).The staining of the granules becomes deeper anddeeper, always maintaining the same bright scarletcolour. In spite of the deepening coloration of thegranules, amoeboid movements will continue, showingthat the cells are alive and that their vitality is appar-ently unaffected by the staining of their is not only the polynuclear leucocytes that behavein this way, but the mononuclear, or lymphocyte,cells as well.
