DESCRIPTION OF PLATE 



All figures were drawn with Zeiss's camera lucida and apochromatic lenses. 



Fig. 1. Guinea-pig 1. Lithium carmine -f- Weigcrls elastic tissue stain 2SO ,i. From 

 the border of the yeast cell group, a free yeast cells in the middle of the 

 group, b immigration of leucocytes in the border, beginning phagocytosis, 

 c emigration from a dermal vein. 



Fig. 2. Guinea-pig 9. Lithium carmine -)- Claudius 2so ;i. Tissue yeast cells lying 

 in hollow spaces ( * ) among fibroblasts. 



Fig. 3. Guinea-pig 5. Lithium carmine -f- Claudius C50 /i. Giant cell formation 

 by mononuclear wandering cells. 



Fig. 4. Guinea-pig 9. Lithium carmine 650 /i. Karyokinesis in fibroblasts. 



Fig. 5. Guinea-pig 1. Lithium + Weigerts fibrin stain 1000 /l. Culture yeast cells, 

 alterated in staining capacity due to their being for 3'/2 hours in the tissue 

 of the guinea-pig.

Fig. 7. Guinea-pig 12. Hrematoxyline + van Gieson 1000 ;i. Vacuolated cells. Dege- 

 nerated yeast cells in the vacuoles of one, granules in another, absence of 

 formed elements in the vacuoles of the remaining two.
