Block 3: Acute diffuse hepatitis (Island 

 2nd aspects). Chronic passive congestion 

 (dilatation of the capillaries with atrophy 

 of the central cells of the lobule). 



Block 4: Chronic passive congestion (di- 

 latation of the capillaries with atrophy of 

 the central cell? of the lobule and central 

 degeneration, with or without dilatation of 

 the capillaries). 



Block 5: Thrombosis of a capillary by 

 masses of bacteria (bacilli). Chronic passive 

 congestion (dilatation of the capillaries with 

 atrophy of the cells in the centre of the 

 lobules and central degeneration, with or 

 without dilatation of the capillaries). 



Block 6: Thrombosis of a capillary by 

 masses of bacteria (bacilli). Chronic passive 



congestion (dilatation of the capillaries

Block 7: Acute diffuse hepatitis (2nd as- 

 pect). Chronic passive congestion (dilatation 

 of the capillaries, with atrophy of the cells 

 of the centre of the lobules and central de- 

 generation, with or withoit dilatation of 

 the capillaries). 



Blocks 8 8:9: Chronic passive congestion. 



Block 10: Acute diffuse hepatitis (1st. & 

 2nd. aspects) and thrombosis of the capilla-

 congestion. 



We would here tender our most sin- 

 cere thanks to Dr. B. C. CROWELL, under

 for his patient instructions and kind advice.
