Book excerpt: Excerpt from The Journal of Experimental Medicine, 1916, Vol. 24 M embrewes. - On opening the eggs on the 18th day of incubation, 11 days after the introduction of a graft of one of the various organs, it was found that aside from the local changes about the graft in the outer membrane, there were scattered through the various membranes small, gray, semitranslucent nodules varying in size from a pin-point to a pin-head (fig. The majority of these contained in the center a small, firm, white dot. This change in the various membranes seemed to be no more frequent near than at a distance from the graft and occurred in other membranes of the embryo than that support ing the graft. T here was considerable variation in the frequency with which this condition was observed. Its most common associa tion was with spleen and bone marrow grafts, but it also occurred in typical form in association with the liver, and, still less frequently, with the kidney. Histologically the nodules were made up of a collection of cells which showed every gradation from the mother cell of both the granular and non-granular white cells of the blood to the typical adult type. Every stage was found from a small clump (fig. 2) of the former to a large dense mass with a necrotic center (fig. Im mediately around the central dead area in these instances was a layer of multinuclear giant cells. Between this layer and the remaining part of the nodule was generally a zone of loose connective tissue. The outer portion was composed of a dense layer of cells of the character mentioned above.
