the length of the spore. In the morning of the next day this
sprout had augmented, and become a filament three or four times as
long. The next day these elongated filaments exhibited some transverse
divisions and some ramifications. On the third day, the germination
being more advanced, many more of the sporidia were as completely
changed, and presented, in consequence of the elongation, the
appearance of a cylindrical ruffle, the cellular prolongations arising
from the germination having a tendency towards one of the extremities
of the longer axis of the sporidium, and more often to the two opposed
extremities, either simultaneously or successively. Out of many
hundreds of sporidia examined during germination, he had only seen a
very few exceptions to this rule, among which he had encountered the
centrifugal tendency to vegetate by two opposed filaments, proving
that if it bears a second by the side of the primal filament situated
at one of the poles, a second would also be seen from the side of the
filament coming from the opposite pole.

Before being submitted to the action of water, the contents of the
sporidia seemed formed of two distinct parts, one big drop of yellow
oil of the same form as the sporidium, with the space between it and
the cell wall occupied by a clear liquid, more fluid and less
refractive, nearly colourless, or at times slightly roseate. As the
membrane absorbed the water by which it was surrounded, the quantity
of this clear liquid was augmented, and the rosy tint could be more
easily distinguished. All the contents of the spore, which up to this
time remained divided into two parts, presented altogether one aspect,
only containing numerous granulations, nearly of equal size,
completely filling it, and reaching the inner face of the sporic
membrane.

After this time the sporidium augments in size very rapidly, becoming
at times irregular, and sometimes even as much as from two to three
times its original dimensions, then there appears at the surface,
usually at one of the poles of the ellipse, a small prominence, with
an extremely fine membrane, which does not appear to separate itself
from that which surrounds the sporidium, and it is difficult to say
whether it is a prolongation of the internal membrane going across the
outside, or simply a prolongation caused by a continuation of tissue
of an unique membrane. Sometimes there may be seen at the point where
the primal filament issues from th
