The participation of the thyroid and of the anterior hypophysis during a complex process of experimentally conditioned immunity was studied in order to establish the concrete modalities of integration of these glands by the central integrative mechanisms. Quantitative microscopy, mathematical and statistical methods, demonstrative graphs, a new mode of expression of correlation types between the phasic quantitative variations of the immune process, as well as a division of the anterior hypophysis into cell groups were used. These methods show that the hypophysis and the thyroid participate in the immunogenic processes with all their constituents (epithelia, mesenchymal cells, capillaries). The importance of the participation vary from one lot to the other. The epithelium dynamics dominated that of capillaries in the glandular organs belonging to the IInd organizational step (with reduced stroma), which allows the consideration of an epitheliocapillary stereotype of organs belonging to the IIIrd step (stroma-rich) described in the VIth note.
