Fig. 15. A piece of a partially attacked endosperm wall more highly 
magnified, shewing groups of 1 connecting threads,’ the 
crenulated edge ( x ) of the unaltered wall shews the method 
of ferment action. Mag. 750. 
Fig. 16. ‘Connecting threads’ in the unpitted cell walls of the 
endosperm, at (y) the wall is seen to possess a shallow 
pit on one side only. Mag. 750. 
Fig. 17. A small piece of cell wall in process of disorganization 
shewing two groups of threads. In one case the ferment 
has bored out a single thread x. Cf. fig. 15. Mag. 750. 
Fig. 18. A piece of the wall of an endosperm cell in surface view, 
shewing that the connecting threads, which together form 
a large group, are arranged in little groups of twos or 
threes each in a slight pit. Mag. 1000. 
Fig. 19. The action of the ferment on the wall in surface view, 
shewing small areas undergoing change, cf. with fig. 18. 
Mag. 1000. 
Fig. 20. A more advanced stage of ferment action, the small areas 
have become merged together with the spread of the 
sphere of action of the ferment, only a skeletal framework 
of unaltered wall being left. Mag. 1000.
