irregular roundish but nearly circular outline, and of about 
0'2 to 0 - 3 mm. in diameter. On the edge it projected from six 
to eight stout protoplasma stems, each of which ramified into 
a very slender tree. These stems, of from O’Ol to 0 03 mm. 
diameter at the base, forked immediately into two, rarely 
into three, branches, which, after running a short distance, 
again forked, and so on. At each division the diameter of 
the forked twigs was conspicuously less, so that each branch 
was usually not half so strong as the next stronger branch of 
the preceding series. The branches were nearly all slightly 
and delicately curved, seldom quite straight. The neigh- 
bouring branches of the third or fourth series already began 
to unite ; and the anastomoses of the branches always be- 
came more numerous towards the periphery, so that the 
outer branches formed a nearly coherent, peripheral, sar- 
code net. The form of the anastomosis was very irregular, 
being towards the periphery more and more crescent-shaped, 
and at the basement more irregularly polygonal. On the 
whole, the plasma net was very similar to that which Claparede 
has figured in his Lieberlcuhnia Wageneri} 
The reddish-yellow colour was most intense in the centre 
of the body ; which also appeared to display the thickest 
layer of plasma ; and in the principal stems which branched 
from the periphery. Near the latter the colour was always 
fainter ; and the finest twigs seemed coloured pale reddish 
yellow. The colour was nowhere so intensely orange red as 
in the previously described balls. As in the last, the colour 
here also arose from a diffused reddish yellow of the struc- 
tureless ground substance, as if produced by a lively yellow- 
ish-red tint of the granules therein suspended. 
The central disc-shaped mass of the body, as well as the 
projecting branches and their twigs, were entirely transpa- 
rent, and also plainly showed with the greatest clearness and 
under the strongest magnifier that the entire mass of the 
body was entirely structureless and homogeneous, without 
any combination of cells or cellular forms. This fact was 
proved by the finer and coarser red granules, which streamed 
here and there in the sarcode net, as well as by the foreign 
bodies and food (namely, Diatomacese) dispersed here and 
there in the plasma. These last were also seized like the 
red granules, and carried away passively by the current which 
was caused by the active movements of the albuminous | 
molecules of the homogeneous plasma. In their chemical com- 
position the albuminous bodies of the plasma or the sarcode
