EXPLANATION OP PI CURES



6 Section through adjacent tumor (Ehrlich sarcoma) — adult spleen graft
after seven days of conjoint growth. The figure represents the part of the graft
not in immediate contact with the adult spleen tissue. A granuloblastic meta-
plasia in the entire mesenchyme of the host took place as a result of the splenic
graft. The tumor cells are seen separated by heavy strands of mesenchyme and
by a large number of 'round cells,' which in this particular case are hem oblast 3,
granuloblasts, and granulocytes.

7 Section through a mixed tumor (Ehrlich sarcoma) — adult spleen graft
after four days of conjoint growth. Only single tumor cells are found, all of them
surrounded by mesenchymal capsules, many of them showing well-pronounced
regressive changes. Retouched photographs. X 400.

8 Section through a mixed tumor (Ehrlich sarcoma) — adult spleen graft after
four days of conjoint growth. Only a very small tumor focus is found. Prac-
tically all the tumor cells, except for a few of them (//. Tc), are in vacuoles, sur-
rounded by mesenchymal capsules.

EXPLANATION OP FIGURES



10 Section through a tumor (180) — adult spleen graft after five days of con-
joint growth. The tumor tissue intensely proliferating, but around it a zone is
found in which the mesenchymal cells are surrounding the tumor cells forming
cellular capsules and digesting them in the so-formed vacuoles.

11 Large magnification, X 1000, of a small area of figure 10. The tumor cells
in the vacuoles are seen in different stages of digestion.

EXPLANATION OF FIGURES



16 Section through a tumor graft, grown eight days on the allantois conjoint
with an adult splenic graft at a wide distance. The tumor tissue is seen intensely
infiltrated by granular leucocytes, the tumor cells widely separated, but still
occasionally found in mitosis.

17 Section through a tumor (Ehrlich sarcoma) — embryonic spleen graft six
days after conjoint growth. The embryonic splenic tissue has undergone an
extensive granuloblastic transformation, the tumor tissue is moderately infiltrat-
ed by granular leucocytes. No digestion zone develops between the two tissues.
