Résumé

Des greffons prélevés dans la moitié postérieure de la ligne primitive achevée des jeunes blastodermes d'embryons de poulet, tués dans l'alcool à 70%, furent introduits sous l'ectoblaste des hôtes de même âge. Dans 15 sur 41 cas, le greffon a exercé une action inductrice sur l'ectoblaste. Dans 18 autres cas, l'action du greffon fut faible, voire nulle. Les inductions provoquées par les greffons rendent le tissu semblable à un tissu neural pauvrement organisé.
