380 ANDREWS. [Vou. XII. 
polar bodies, thread-like processes with some wave-like change 
of contour were noted on these little lumps, the egg being at the 
time under magnification of three thousand diameters. These 
initial protoplastic activities were extended, and multiplied from 
other portions of the hyaline protoplasm enveloping the nuclear 
substance. 
Delicate threads and ray-like processes grew out on many 
sides, and the shape of the whole mass suffered change from 
moment to moment, both from the actual displacement thus 
caused and from an apparent pulling here or there of the little 
cells by their attached filaments and strands which had formed 
actual connection with the egg pellicle or membrane. 
It seemed to me to be from this time, z.e., when the threads 
from the polar bodies effected reunion with the parent cell, 
that the egg spinnings were again renewed. However this 
may be, it was certain that from this time forward, throughout 
the entire cleavage of the egg up to a late larval stage, the 
egg and these bodies were united by their individual spinnings, 
which formed an unstable, and at times evanescent, series of 
interlaced and anastomosed networks. These more or less 
surrounded the polar bodies and stretched across the cleavage 
pore. 
The processes from the polar bodies were finer in general 
than the average egg filament, but this was variable, and along 
the finest filaments would often pass little masses, relatively 
large in quantity, of flowing protoplasm which might collect 
here, or there, and form nodes as it were, and these became 
centres of renewed and somewhat independent spinnings. 
From moment to moment, the substance composing the net- 
work, or its islands of protoplasm, would return wholly to the 
polar bodies, to be again sent out in a new direction and to 
assume a new form. 
The globules seemed to delight, especially later on in the egg 
history, in forming brush-like tufts, or skeins, of finest fila- 
ments, which often assumed a curious, superficial resemblance 
to a spindle, spreading at a little distance from their point of 
origin and then again drawing together at their point of fusion 
with some ray or strand, or with the nearest egg cell.
