8, are essentially like those shown in figure G, plate 5. In figure 
E the section passes through the middle of only one nucleus, 
but it shows a small portion of the other. However, the light 
areas appearing around the chromatin lie almost in contact, and 
reconstruction is far from being completed. The nuclear mem- 
brane has not yet appeared and the chromosomes have not lost 
their identity although they have the ragged appearance de- 
scribed above in the reconstruction of the nucleus in Taenia. If 
reconstruction should be completed, the nuclei would undoubt- 
edly he in as close contact as the two nuclei shown at 1 of the 
same figure, if not closer. 
There is also the same variation in the condition of the chro- 
matin in Moniezia as there is in Taenia. Some of the nuclei 
show the chromatin in a finely granular reticulum, typical of a 
resting stage, others a more coarsely granular reticulum, bor- 
dering on the formation of the spireme, and still others show the 
spireme in almost all degrees of perfection. No one of these con- 
ditions is confined to any particular sized nucleus. The reticulum 
is found in the large as well as the small nuclei. The same is 
true of the spireme. In figure D are shown three nuclei in a 
row and in close contact. The chromatin of the middle nucleus 
is in a spireme, while the chromatin of the other two nuclei is 
in a finely granular reticulum. In figure C two nuclei lie so 
close together that the surfaces of contact are flattened and yet 
the chromatin in each nucleus forms a perfect spireme which is 
in contact with a large nucleolus. The two large nuclei of figure 
A are in as close contact as those described in figure C, but the 
spireme is much less perfect, while the chromatin in the two 
smaller nuclei of the same figure forms an almost perfect spireme. 
The same variation is shown in all the figures of this plate. If 
the fact that the chromatin is in the form of a spireme, be an 
indication of mitosis, the two small nuclei of figure A are in the 
prophase of mitotic division. 
The character of the cleavage, the reconstruction of the nu- 
cleus, and the character of the chromatin in the nucleus in 
Moniezia offer no more indication of amitotic division than they
