46 SPERMATOGENESIS AND FECUNDATION OF ZAMIA. 
of the original blepharoplast. In the cell shown in figure 35 the gran- 
ules are from one-half to 1 “in diameter and stain deep purple with the 
Flemming triple stain, as does the nuclear membrane. The mass of 
granules here occupies more space than the daughter nuclei and form 
a somewhat rectangular mass from 10 to 13 4 wide by from 20 to 22 yu 
long. The cell figured here is smaller than usual, being only 132 by 
174 4. The radiations from the blepharoplast would seem to be simply 
accentuated strands of the reticulum, the radiations running irregu- 
larly and corresponding with the walls of the cytoplasmic meshes. 
The radiations are by no means plain in this stage, and end rather 
indefinitely when they approach the granules of the blepharoplast. 
There is no indication of any membrane surrounding the blepharoplast 
in this stage. | 
In a late telophase, when the daughter nuclei approach a resting 
condition they are found to have greatly increased in size, while the 
group of granules remains of comparatively the same size, and to all 
appearances unchanged. In this closing stage of the division, how- 
ever, a most wonderful process is just starting the organization of the 
cilia-bearing band of the spermatozoid, which is formed by the union 
of the granules of the blepharoplast. At tirst the band can be detected 
only as a delicate, short, deeply stainable line, extending from the 
group of granules of the blepharoplast toward the nucleus. At first 
apparently only one of these lines can be observed, but shortly, as 
development progresses, a similar line can be observed protruding 
from the mass of granules on the opposite side (fig. 39). At first the 
band is very narrow, being scarcely more than a line. It gradually 
increases in width, however, as it increases in length, till it soon has 
an appreciable width. While there would seem to be no possible 
doubt that the band is organized at the expense of and by the gran- 
ules of the blepharoplast, the details of the process of the organization 
is somewhat difficult to discover. In some sections the writer has 
been able to distinguish what seems to be individual granules of the 
blepharoplast fusing with the band where it joins the mass, several of 
the granules that have united with the band still showing their indi- 
viduality (figs. 86 and 37). Again, in bands which have developed 
considerably the thickness seems to be continually added to by the 
fusion of other granules with it directly on the edge which les next 
to the mass of granules (figs. 38 and 64). It is not infrequent to 
find sections showing indications of this sort, which suggest the union 
of the granules together to form the band. Furthermore, as the 
band grows in length the granules of the blepharoplast gradually 
disappear till all have been absorbed in the growing band. The 
writer thus feels that there is little doubt of the correctness of the 
interpretation. This history of the origin of the cilia-bearing band 
by the fusion of the granules of the blepharoplast was first described
