Poultry Review.
An infertile egg, or rather one with
out a germ, is termed clear" A fer
tile egg becomes added" or rotten,
when the germ dies before the chick
is formed.
Life is p~erceptible about a day after
incubation begins. The first appear
ance of red blood is found on the
yolk-bag toward the close of the Sec
ond day. The pupil of the eye can be
distinguished on the fourth day. The
lungs begin to form on the fifth day.
The gall-bladder is first seen on the
sixth day. The bill is noticeable on
the seventh day. The bones are shaped
On the ninth day. The muscles of the
wings are completely formed on the
tenth day. The arteries begin to be
distinct on the eleventh day.
On the twelfth or thirteenth days,
if the membrane enveloping the white
of the egg be examined very cautious
ly by opening the shell, it will present,
blumenbach says, without any artifi-
cial injection, one of the most SPLEEN
did spectacles that occurs in the whole
organic creation-the most simple yet
the most perfect substitute for lungs,
1t exhibits a surface covered with
countless blood vessels, venous and
arterial, branching through it's texture,
The veins are of bright scarlet color,
carrying oxygenated blood to the
chick; while the arteries, on the other
hand, are of a deep, crimson or Iivid
red, bringing the ~carbonated blood
from the body embryo. The functions
CT the two are thus the reverse OF
those they perform after the chick
rcspires.
On the fourteenth day the feathers
appear, well developed.
Day after day then the growth goes
on, and by the ninteenth day the
embryo frequently utters a sound. On
me twenty-first day the shell breaks
and the chick is born.
There used to be a belief hat the
chick was freed by the mother break
ing the shell. The use of artificial
methods for Matching has clearly
proved that belief to be wrong.
Present day poultry science gives
these facts in the development of the
el lex.
Twelve hours after incubation has
begun; the lineaments of the head and
! tody are discovered. Close observa-
ton has found the heart to beat by
the close of the day. At the end of
f~Uurty-eight hours vesicles of blood
are distinguished, and pulsation OF
which are visible. At the fiftieth
hour, an auricle of the heart appears.
At the end of seventy hours, undis-
t1nguished wings, and on the head
two bubbles for the brain, one for the
bill, and two others for the fore part
n the hind part of the head. The
liver appears toward the fifth day. At
the end of h one hundred and thirty
Ii hours, the first voluntary motion
is observed. Seven hours later the
lungs and stomach become visible,
and the intestines, the loins, and the
| upper jaw are seen at the end of one
hundred and forty-two hours. The
seventh day, the brain, which is Shiny,
begins to have some conSistence. Al
the one hundred and ninetieth hour of
incubation the bill opens and the flesh
appears in the breast. Four hours
after that the sterum is SEEM that is
to say, the breast bone. At the two
hundred and tenth hour the ribs come
out of the back, the biol is very visible,
as well as the gall-bladder. The bill
becomes green at the end of two hun
drcd and thirty-six hours. About four
hours later the feathers begin to shoot
out, and the skull becomes gristly.
The eyes appear at the two hundred
and sixty-fourth hour and at the two
hundred and eighty eighth hour the
ribs are perfect. At the three hun
dred and thirty-first hour the spleen
draws near to the stomach, and The
lungs to the chest. At the end of
three hundred and ffty-fve hours, the
bill frequently opens and shuts, and
at the end of four hundred and fifty
one hours, or the eighteenth day, the
first cry of the chick is heard.
Thus it is by so many different de-
grees that these creatures are brought
into life. All those ~progressions are
made by rule, and there is not one
without sufficient reason. No part of
it's body could appear sooner or later
without the whole embryo suffering;
and each of its limbs appear at the
proper moment.
How astonishing, says a noted Eng
llsh writer, that all the parts of an
animals body should be concealed
within this egg, and require nothing
but heat to unfolk and quicken them
into life-that the whole formation of
the chick should be so constant and
regular that at exactly the same hour
all these changes will occur, in the
generality of eggs, and that the mo-
ment it is Matched it is heavier than
