But this operation has lis limits. IL does
not extend beyond plants having a certain
affinity. The apple tree may be planted

cases prove that the same food suiiices
Tor the apple and the pear: They equally
prove that different foods are required
for tie apple and the peach. Ii is SAID

precisely so. Certain manures succeed

crops. But this and similar examples
prove only that some ingredients are the
same III all animals and plants; not that
all the ingredients in each are the same.
he chemist, though as yet a fellow
student, as much as preceptor Of the
agriculinrist, justly claims attention TO
Inc result OF his processes. From that
source we learn thatthe number Of knowu
elements, not Yet decompusabie, is be-
tween forty aud fifty that about seven
or eight belong to Tie organs OF plants
that different elements enter into the COM
position of the same plant: and that they
are combined in diiierent numbers and
IN different proportions, III different
plants. Surprising then us must be sup
posed, that these different clements, in
their actual quantities auA proportions,
are adapted 10 Ike quon,ii.cs and the
proportions Of the existing varieties of
plants; II would happen III so great a
change as that in question with respect
tn the number and variety of plants, that
! the quantities and the proportions of tie
element would not be adapted 10 the
| particular kinds and numbers of plants
retained by man for his own use. Like

the atmosphere and organized beings?
! Animals including man, and plants NAV
| be regarded as the most important part
OF the terrestrial creation. They are pre-
eminent III their attributes and all ma
| ture teens with their varieties and their
muitlludes, visible and invisible. To al!
| OF them the atmosphere Is the breath OF
life. Deprived of 1t, they all equally pc
rsh. Bu, 1T answers This purpose by vir
| tue OF It's appropriate constitution and cha
tacler. What are these?
| The atmosphere is not simple but a
compound body. In IFS least compound
state, ii is understood 10 contain, besides
what is called vital air, others noxious in
themselves, yet without a portion of
which, The viial air becomes noxious.
But the atmosphere lii It's natural state, &
III lis ordinary communication with the
organized world, comprlzes various ingre-
dents or notifications of ingredients de-
rived from the use made ii, by the ex-
isiing variety OF animals and plants.
The eXha!aiions and preparations, the
ettiuvla and transpilalions of these, are
continually charging the atmosphere with
|
quantity of matter, which together must
contribute 10 the character which fits 1T for
its destined purpose disappearing the life
and health of organized beings. Is if
unreasonable TO suppose, that if instead
OF the actual composition and character
| OF the animal and vegetable creation, to
| winch the atmosphere is now accOmoda-
ted, such composition and character of
that creation, were substituted, as wGuld
| result from reduction Of the whole to
man anda iew kinds Criminals and plants
| is The superstition unreasonable that the
change might essentially affect The anti
tudc of the atmosphere for The functions
required oft; and that so great an inno-
yation might be found in this respect.
MOTTO accord with ttte order and economy

vegetable part Of the creation 10 each 9th

! phcre. comes in aid Of iIie reflection suq.
| gesied by the general relation between
| The atmosphere and both. Ii seems 10 be
AowWeil understood, that the atmosphere

when evolved by the latter, il is reiitted
tor the respiration Of Tie former: an in

May it not be concluded from This adj
mirable arrangement and beautiful fea-
