ON the influence of certain chemica
factors, among which heat and mois
ture may be regarded as paramount
The organisms now living on this
earth are known as plants and ami
mails and without exception one anG
all are subject to the same laws. This
makes for close correspondence
among all life and thus it is possible
for US to unravel and expose the tan
gled sources of our physical ills with
comparative ease. The study of plants
Is called botany and that of the ami
mails Is known as zoology, while the
study of living things in general, in
Guiding both animals and plants. is
known as biology. Humanity owes a
vast debt to biology and that debt is
increasing every day.
Biology teaches us that there is no
room for chance in nature and that
unrestricted growth never results in
diseord. Discord is always artificial.
Wherever there Is any unnatural"
condition We know there must have
been some interference to account for
1t. And the present drift in the medi-
cal world is to locate this interference.
Research work conducted along
these lines with fish, chickens and the
like has recently exposed many inter
esting and extremely Illuminating
facts with relation to the subject Of
the disease known as cancer, and
makes 1t very clear that we easily
might solve most Of our physical trou.
bles In much the same way II we
would only learn to heed the lessons
acquired in the handling of the lower
organisms
Incubation Is word in common
use; 1t Is derived from the Latin words
meaning to brood. or to lie on, and
specifically 1t means the action of the
hen in sitting on her eggs to hatch
them; the word is also used In pathol.

within the human body of the germs
OF disease, and it is especially asso.
ciated with the artif. cial means of
Matching eggs with incubators or for
any analogous purposes Of an artificial
foster"mOther nature. Artificial incu-
baton was known to the Egyptians
and to the Chinese almost from time
immemorial, but it is of comparatively
recent use In this country.
If 100 ordinary fertile hens eggs are
placed in an incubator equipped with
a suitable device for regulating the
amount of heat, air and moisture ad.
mitted, and 1t be regulated to main
tain a temperature Of approximately
103 degrees Fahrenheit, very marked
changes may be noted in the interior
of the egg from day to day as the re-
suit of the absorption of the heat.
Assuming the temperature and mois-
ture in the interior Of the incubator
to have been normal, Gambling the 100
eggs on about the fifth day of incuba-
ton will reveal remarkable changes
taking place in them: the developing
germ, with blood vessels radiating
from it like spider web, will be dis
tinctly visible. Gambling again about |
the tenth day will show further ad- |
vance, and at this time usually not a |
few Of the developing chicks will be |
found to have died. The percentage |
dying at this stage Is determined by |
the general vitality of the flock laying
the eggs. II for any reason the flock
Is not in normal condition there will |
not be sufficient vitality In the germs
to carry them further and they die.
Again on the fourteenth day 1t is GUS
tomary to candle or test for the dead
ones. for again there will be some
with only sufficient energy to get this
lar. Between the tenth and fifteenth
lays the chick becomes relatively
arge and bulky, the temporary re-
'piratory apparatus. together with its
veins, increases greatly in size and ex-
ent and the life processes proceed
with greater activity. On the nine
eenth day it is the rule again to
search for the dead ones and then the
Machine is usually not touched again
Until the hatch is completed.
If the temperature and moisture
lave been maintained approximately
formal, the chicks will break through
heir shells on the twenty-first day.
Chicks resulting from a normal
latch are active and alert. They be-
lin to pick about and feed as soon as

r premature or delayed hatch are
Inactive from the start, not alert and
