Drs. Herring and Simpson. Relation of the [May 31, 



Fig. 2. — Liver cells of normal dog. Eosine and methylene blue. 



Four liver cells are shown, in three of which the nucleus contains a crystal. 

 The crystal is of a different size in each. The nucleolus lies close to the 

 nuclear membrane opposite the middle of the crystal. The nucleus of the 

 fourth cell contains a rounded mass of a material which stains like the crystals; 

 its nucleolus lies on one side, close to the nuclear membrane.

The sinusoidal character of the blood-vessels and the incomplete nature of 

 their endothelial lining are seen. 



One small endothelial cell is closely applied to the junction of two liver cells 

 in the middle column. Two of Kupffer's cells are shown. They are large cells 

 with processes and appear to lie free in the sinusoids. A space exists 

 between each of them and the neighbouring liver cells. In the lower cell 

 represented this space is partly occupied by red blood corpuscles. The cyto- 

 plasm of both cells contains granules staining intensely with eosine. 

 Fig. 4. — Section of rat's liver. Hsematoxylin. 



The aorta was injected with carmine gelatine at a pressure of 80 mm. Hg ; 

 inferior vena cava open. The injection mass occupies channels between and 

 inside the liver cells. 

 Fig. 5. — Section of rat's liver. Hsematoxylin. 



The aorta was injected with carmine gelatine at a pressure of 100 mm. Hg ; 

 inferior vena cava ligatured. 



The liver cells contain more injection mass than do the cells in fig. 4, but it 

 is largely in the form of separate drops. 

 Fig. 6. — Section of monkey's liver. Hsematoxylin. 



The poi'tal vein was injected with carmine gelatine at a pressure of 

 60 mm. Hg ; inferior vena cava open. One of the liver cells contains a fine 

 network of injection mass ; in others there are small accumulations of the 

 injection in the cytoplasm. 

 Fig. 7. — Section of dog"s liver. Hsematoxylin. 



The aorta was injected with carmine gelatine at a pressure of 100 mm. Hg ; 

 inferior vena cava ligatured. There are channels filled with injection between 

 and inside the liver cells. 

 Fig. 8. — Section of cat's liver. Hsematoxylin. 



The aorta was injected with carmine gelatine at a pressure of 100 mm. Hg ; 

 inferior vena cava ligatured. The injection mass appears in fine channels in 

 the cytoplasm of the liver cells. 

 Fig. 9. — Section of fowl's liver. Hsematoxylin. 



Hight aortic arch injected with carmine gelatine at a pressure of 100 mm. Hg ; 

 inferior vena cava open. The sinusoidal character of the blood-vessels is seen. 

 Fine channels pass between some of the liver cells, and the cytoplasm here and 

 there contains injection.

 acid and methylene blue. 



From a case of fatty embolism clue to chloroform poisoning. 



The liver cell contains globules of fat, and a direct connection is apparent 

 between the fat in the cytoplasm of the cell and fat in the blood-vessel.
