388 ANDREWS. [Vor. XII 
To some interchange of the protoplasm between cells, which 
may be but temporary, or may be part of the organising phe- 
nomena: 
To an actual desire on the part of the cells for such physical 
connection and physiological communion among themselves; 
and a coherent attempt to regain and continue these conditions 
after they have been artificially destroyed : 
To a continued, and to great degree independent, existence 
of the polar bodies after their extrusion: and to their acting as 
part of the coalition of cells up to a late period, yet without self- 
multiplication, and with marked distinctive features of their 
own, which are peculiarly protoplastic. 
The facts assert also: 
That the peripheral substance of egg and cells is freely proto- 
plastic, despite its appearance under less magnification of being 
a smooth and stable pellicle : 
That the ectosarcal formations of these Metazoan eggs are 
possessed of tactile power such as characterizes similar modifi- 
cations of the substance in protoplasts : 
That considerable deportation of living substance can take 
place from egg or cells in a manner invisible to even quite high 
powers (as 1500 diameters), and yet to an extent producing a 
measurable diminution in size of the mass from which it is 
carried : 
That, in short, the measure of the living facts cannot be taken 
truly with anything less than our best optical resources, and 
that even these fail of perfect adequacy : 
That apart from the grosser organization of the egg, which 
we have had spread out to some extent before us by reagents, 
there exists a minuter mechanism which these fail to record, or 
even hint to us; and that beneath the interactions of those 
grosser masses which seem so complete as seen under lower 
powers, there are supplementary and strongly causative inter- 
actions of minuter portions of the substance composing them, 
which are in part visible with our highest powers and which are 
from some points of view curiously contradictory in seeming : 
That while the grosser organization acts through more 
definite and stable structures, the finer, and heretofore unseen,
