The Nuclear Plasm resembles that in the apical cells, or 
occasionally is less dense. 
The Nucleolus is as in the nuclei of the apical cells. 
The Effect of Stimulation for One Minute on the 
Lateral Superficial Gland-cells. Type 1. Fig. 14. 
The Cell Wall is pale purplish pink. Its turgor is un- 
changed. 
The Cytoplasm is attached to the basal and lateral walls, but 
shrunken towards the apex. The distribution is like that of 
unfed specimens. Its coloration is pinkish purple, and fairly 
uniform throughout the cell. A blue ‘ corpuscle” is usually 
present in the cell-plasm. 
The Nucleus is normal as to position, size, and shape. It is 
slightly deeper in colour than the cytoplasm surrounding it. 
The Nuclear Chromosomes are as in unfed specimens. 
The Nuclear Plasm is unchanged in structure, but shows 
slightly more affinity for red than in unfed specimens. 
The Nucleolus is deep purple-red, and is surrounded by 
Frommann’s zone. The endonucleoli are less distinct than in 
unfed specimens. 
Nore.—The lateral superficial gland-cells at the base of this 
tentacle-head show a much redder coloration than the other 
cells of the layer, and therefore resemble fig. 15. 
Effect of Stimulation for One Minute on the Lateral 
Superficial Gland-cells. Type 2. Fig. 15. 
The Cell Wall is extremely pale purple. There is no red 
coloration between the cells. 
The Cytoplasm is retracted from the basal and lateral walls, 
but not from the apical to which it is closely applied. The 
general distribution of the cytoplasm is like that of controls. 
In colour it is like that of the apical cells,—that is, red 
round the nucleus, becoming bluer towards the periphery. 
The blue “ corpuscles” are present as a rule. 
The Nucleus is normal as to position, size, and shape. It 
is of the same shade of colour as the cytoplasm surrounding
