speuiiatic evolution in toe common
This figure represents the
several stages of evolution of
the spermatic animalcules of
certhia fam Maria (common
creeper). As a greater de
gree of force has been given
to the outline than is to be
met with in nature, the figure
rather resembles a plan than
an exact copy of what may be
observed. The objects are
delineated as magnified from
nine hundred to one thou
sand times. I. An adult sper
matozoon taken from the ori
fice of the vas deferens, a.
Seminal granules, taken from
a very collapsed teslicle in
the winter season, b, k. Sev
eral seminal granules, taken
from a testicle in summer,
during turgescencc. b, o.
Seminal granules, which are
probably nothing more than
altered epithelial cells, d, e,f.
Cysts or vesicles, inclosing
one or more round granular
globules, g. A similar cyst,
besides the two
containing,
globules, a finely granular
mass, in which the sperma
tozoa may be seen to form.
li. The cyst, still containing
some finely granular matter,
has assumed an oval form,
and the bundle, of spermatic
animalcules,increased in size,
lies bent up within it. i. A
cyst still more developed,
the involucrum, pear-shaped,
covers the bundle of animal-
cueepee. cnles where their spiral extre
mities lie. k. A cyst arrived at maturity, still covered by the involucrum.
