third of the cell, so that cells of this stage can be easily re- 
cognised with low powers. The thick granulation stains a 
deep purple. The matrix appears to stain the same colour, 
but fainter. Below the nucleus are one or two very large 
vacuoles, Above it the space is either occupied by one or two 
large vacuoles, or, as in the cell figured, a protoplasmic net- 
work traverses the upper third of the cell, enclosing numerous 
smaller vacuoles in its meshes. 
The Nucleus is in position, size, and shape as in unfed 
specimens. It stains of the same tint as the cytoplasm, and 
therefore lacks the clear definition which is characteristic of 
the resting state. 
The Nuclear Chromosomes are in the form of numerous 
granules of slightly larger size than in the resting state. They 
have a somewhat undefined appearance, and want of clearness 
of outline. 
The Nuclear Plasm is granular. It resembles very closely 
the cytoplasmic granulation in every way ; so that the nucleus 
appears to be only a portion of the cell-plasm enclosed by a 
broken ring of chromatin granules. 
The Nucleolus is either very pale and transparent, and 
usually very small, or is quite undiscernible.

Leaf thoroughly opened up, and glistening with 
exuded drops). Fig. 12. 
The Cell Wall is pale blue. 
The Cytoplasm has retracted as a whole from the cell walls, 
but is attached in the basal third at various points, as is the 
general rule, both in controls and fed leaves. It is densest 
near the nucleus and below it. In the rest of the cell it is 
largely vacuolated. In structure and colour it is exactly like 
that of unstimulated glands. The vacuoles are large and 
numerous, and their contents are perfectly homogeneous, and 
are unstained ; though usually the vacuoles appear to have a 
bluish tinge in mid-focus, caused by underlying or overlying 
plasm.
