Fig. 3. A transverse slice of the same spleen soaked in dis- 
tilled water 20 days, when the mucus was almost wholly dis- 
solved, and all the colouring matter discharged ; but this slice 
having been kept in a deep glass quite full of distilled water, 
and closed with a glass stopple, no atmospheric air could pe- 
netrate ; the mucus and colouring matter were washed out 
before putrefaction could take place ; the remaining globular 
substance then was so loose, that by the least motion of the 
section of the spleen the margins of the cells crumbled and fell 
to pieces. Of the natural size.

Fig. 1. A transverse slice of the spleen of a boy ten years 
of age ; the spleen being kept in water 48 days, the mucus 
and. the colouring matter were entirely dissolved and dis- 
charged ; and fresh water being pumped every second day 
upon it, the globular substance was gradually completely 
washed out, and the arteries, to their most minute branches, 
became perfectly clear and distinct, no other parts being left.
