This performs every office of a tegument to the ovulum 
during its younger stages, and as the testa occasionally does, 
it becomes during the formation of the seed, so fine, as to be 
scarcely, if at all demonstrable; it may readily be mistaken 
for a testa or tegument, especially if carelessly dissected, but 
its existence in the barren cell, and its being perfectly closed, 
demonstrate that it does not belong to the ovulum, indepen- 
dently of the considerations derived from study of the deve- 
lopment of this, and its entire structure.
