According to Prof. Huxley, can idea, or
mental impression, passing to the brain, pro-
duces a change in the molecular PARTICLES of
the brain substances. The way thus being
broken, subsequent impressions of the same
kind are more easily transmitted, /" There
is an economy shown in nature, by which
faculties not brought into use-that is not
d~eveloped-in time become extinct. Fish in
the Mammoth cave have no eyes. DR.. Jo-
seph Thomas, speaking ofEgypt, ssys:"Of
all the trades pursued in this country, the
most remarkable is Matching OF eggs by the
artificial heat of ovens, a popularity of
Egypt, handed down from ancient times.
The poultry reared in this way are wholly
without the instincts which relate to the
care of offspring the artificial method of
Matching, therefore, when once resorted to,
soon becomes necessary, and the natural
system of incubation is totally superseded"
In an address before the Massachusetts
Board of Agriculture, Prof. James Law, Of
Cornell University, set forth the following
important principles for breeding animals !:
l. A perfect development and sound, Wig
orous health, constitutionally, especially in
the generative organs, are conditions of fer
tility. sk III
2. In the maintenance and improvement
ola breed, the truth that &c like produces
Ike that the reproductive germ will stamp
upon the animal developed from it the char
acters of the parent organism, is the back
bone of success.
3. We can, in a great degree, at will j;
produce variations and improvements in
breeds, as, by abundant feeding, a mild and
salubrious climate, a rich and healthful soil,
moderate use, education, stimulation or Sc
lection Of desirable qualities; by disease or
rejection of undesirable characters andlprop-
critics by soliciting the weight OF imagina-
ton in our favor , by allowing the breeding
animals to mix only with those of the stamp
desired; by crossing less improved breeds
systematically with males of a better race /;
and by crossing animals faulty or deficient
insome particular point with others in which
this point is developed in excess.
A.. The herding of pregnant high-class
animals with low-bred ones, and the result.
ing attachments between the two races, are
to be especially avoided, as occasionally at
fecting the progeny injuriously strong i'm
pressions from q new or unusual condition
of surrounding objects are to be equally
guarded against.
5. If valuable female is allowed to breed
to an inferior male, she can not be relied up
on to produce pure-bred animals for several
succeeding pregnancies. Through a stroag
and retained impression, through the absorb
ton into the system Of living particles (ger-
minal matter} from the f9tus, or through
SOM influence during pregnancy on the ova,
then being most actively developed, the
good or bad features Of the first sire are per-
petuated in the progeny Of succeeding ones.
6. All breeds show a tendency to.'breed

marks of their less improved and COMPARE,
