disappear almost entirely, and the outline of the nucleus be- 
comes less distinct. Glucose and saccharon are now abundant 
in all the cells, and can also be detected in the cavity of 
gland and duct, if very thick sections are used. 
I was not able to ascertain accurately at what stage the 
sugars are first passed into the cavity, because any sugar 
in solution in the cavity is immediately washed out on placing 
in the hot Fehling’s fluid ; for this reason a section taken 
across the ovary, even when the flower is open and the gland- 
cavity and duct consequently filled with saccharine liquid, 
does not appear to contain any sugars. If, however, very 
thick sections be used, a few particles of cuprous oxide can 
generally be observed in the cavity adhering to the walls ; 
but such appearances are by no means a trustworthy indica- 
tion, as they might easily be derived from the contents of 
the surrounding cells which have been ruptured.

I may here notice that neither at this nor any other period 
during the activity of the glands could I detect any sugars in 
the intercellular spaces of the surrounding septum-parenchyma, 
and that as a general rule the epithem cells next the 
same contained much less sugar than those nearer to the 
epithelium.
