Again, I have not satisfied myself that the cell-like structures 
occupying the mass of the body are really cells — that is, I 
have not seen that they possess a special wall, though the 
bright spot in each, with its central black dot, may, most 
probably, be regarded as nucleus and nucleolus, and homolo- 
gous with the white space and darkish dot in centre of the 
cells of last form. These bodies in the present are of that 
bluish hue and granular appearance prevalent in such forms. 
The central nucleus, so to call it, is of a circular or broadly 
elliptic outline, and is bounded by a distinct, sharp, black 
line; its colour seems to vary, and this, with the kind of 
illumination and of the state of the focus of the microscope, 
from a bright yellow to amber and red. When focussed low 
down it appears red, a shade higher of an orange or amber 
hue, and focussed high it assumes the colour of a bri ght 
speck of flame. Viewed under a moderate power the colour 
evinced is reddish, the quantity of these bright specks 
giving a red character to the whole creature. There is gene- 
rally but one of these bright dots in each, but occasionally 
two in certain of them which present a more elongate outline, 
perhaps indicating self-division, as in the last form. With a 
certain position of the focus the black dot is evideiit in the 
centre of nearly all these bright eye-like specks. The gene- 
ral sarcode mass of the body often closely envelopes the 
central cells, and at times the figure of the creature ap- 
proaches the globular, though elevations and various distor- 
tions frequently occur. Sometimes, however, specimens are 
met with comparatively poor in the central cells, and the rather 
hyaline sarcode body-mass can then be seen ; and such can 
undergo a multiplicity of shapes, and the creature presents 
an activity and locomotive power quite surprising, if one’s 
acquaintance with this form should be made with the globular 
inert condition. I have several times, in watching the move- 
ments of a freshly- taken lively specimen, seen it actually tear 
itself into two, and each portion become rounded off, and 
survive as a distinct but smaller individual ; and this for no 
evident reason, that is, quite spontaneously and even rapidly. 
A triangular cleft makes its appearance at one margin, which 
becomes deeper and deeper ; but this cleft is not a complete 
severance of the sarcode at each side, for it remains connected 
by numerous fine linear threads, just like the marginal 
pseudopodia, except that for the present they remain con- 
nected at both ends with the body-mass. Presently the tear 
extends downwards, and the slender sarcode threads give 
way at the upper part of the cleft, some remaining to belong 
to one of the separated margins, some to the other. This
