No. 2.] SPJVNMING ACTIVITIES OF PROTOPLASM. 381 
By shortening of the filaments, the position of the globules 
was changed, these being drawn here or there ; and later their 
shape underwent strange changes which forced one to correlate 
them with existing thread formations. Now they would be 
seen as irregularly spindle-shaped, with bundles of radiating 
filaments arising from each end of each body; then as spherical 
masses, with Heliozoan-like rays extending from all sides nearly 
alike ; then again as colonial groupings of separated minor 
masses of protoplasm connected by filaments and having the 
chromatin granules distributed to some extent among the 
larger lumps; then again, with filaments almost entirely 
withdrawn, as amoeboid shapes with delicate wave-like expan- 
sions of substance flowing in protean manner about the 
granules which were then perhaps collected together at some 
one point. 
Delicate vacuolations of variable sizes appeared and disap- 
peared in the main masses and in their smaller colonizing 
masses. 
The protoplasmic granules were transported here and there 
along the processes, and the filaments underwent all those 
changes of optical quality which have been described in the 
egg spinnings. 
The change of position and grouping of the chromatin 
granules were deeply interesting, for they were at times 
scattered, then drawn in line, then variously grouped. But 
I was unable to determine any coherent significance in these 
differences at the time, and dare not so much as guess that 
their arrangement was other than fortuitously and mechanically 
altered by flux of the surrounding substance. 
The granules’ presence, even singly, in any mass of the 
cytoplasmic spinnings certainly seemed to be correlated with 
more continuous, persistent, and in a way organized, displays 
of this sort. 
From all the surrounding cells, passing filaments gave of 
their substance from moment to moment to the compound net- 
work which compassed the bodies about, and it was not always 
possible to know from what source a given portion of the 
network had come nor whither it was bound. It was always
