It was shown that the argyrophil structures of animal thymus connective tissues (reticulum fibers, reticulum cells, histocytes) are resistant to x-rays, preserving their structure and argyrophil properties when exposed to large doses (1000-3000 rad). In irradiated animals the structures enumerated being demasked because of emigration and destruction of lymphocytes are identified more adequately than those in intact animals. In the cortical zone, the reticulin fibers were largely contained by vascular walls. In the medullar zone, the thin fibers formed the network reaching the Hassal bodies. Argyrophil reticular cells and histocytes were spread through the whole lobule, the largest groups of histocytes being located around the Hassal bodies.
