envelope (periplasma) then encloses the oogonium, 
which thus becomes an oosphere. Close to this, on 
the original filament, a small swelling appears, which 
Ferran regards as the pollinidium, or antheridium, 
which is intended to fertilize the oosphere and trans- 
form it into an oospore. 
When the rupture of the oospore occurs, the 
granules contained in it float in the liquid. Those 
which have been fertilized grow until they are as 
large as the original oogonium, and constitute mul- 
berry-shaped bodies, so called on account of the 
numerous round projections or micrococci which 
cause the surface to resemble that fruit. 
A very slender filament may soon be seen to issue 
from one of the points of this mulberry-shaped body, 
a filament which grows longer, and sometimes two 
of them appear at once. These filaments’ become 
sinuous, twist in spirals, form spirilla, and are then 
segmented so as to form by fission Koch’s comma 
bacilli, which are the starting-point of the culture, 
and of this cycle of evolution (Figs. 88, 89, 90). 
Hence it would appear that the cholera microbe 
must belong to a much higher group than that of 
bacteria, to which it has been hitherto assigned. 
This mode of reproduction would show that it is not 
an alga, but a fungus of the group of Peronosporew, 
and it is, in fact, termed by Ferran P. Barcinone 
while his friends prefer to call it P. Ferrani, after its 
discoverer.
