The Atmosphere and it's Effects upon Animal
Life.

:
Animal Life" Some of them would he surprised
to hear that they lived at the bottom of an i'm
| meuse ocean of air fifty miles deep: yet II was
So and the color of this ocean. which is called the
atmosphere. is deep corulcan blue. To perceive
this, it necessary to be- able to see Mt once
| the whole volume, and also on calm and clear
day, for no color could be perceived If seen in
small quantities. or when there was either wind
on hnzncss. In like manner, the color OF winter
cannot be seen in small quantities, aud was only
| perGeptible where there was n vast e&panse -
occnn. The air was also n substance capable OF
condension and expansion. Its expansion was
| seen in the winds, by which ships were made to
| traverse the ocean, and also in windmlls. The
tornado was another phase Of its expansion, by
which trees were uprootcd and houses overtnrn-
ed and was almost equal to the power OF steam.
| The greatest weight of the atmosphere was iii
| teen pounds to the square inch and this weight
| presses ON every way, both upward and down
ward. Ioexplnn the pressure upwards the lee
! turcr exhausted the mir out of large vase, which
then remained fast 10 the plate on which it stood,
but on the mir being let in il was easily removed.
| remember, snd he, being asked the question, if
there is pressure of fifteen pounds to the square
! inch, the reason why we were not at once crush
| ed 10y the weight; but this is, as before explain
! ed, because the air presses in all directions with
the SAME cqunl force aud hence there is an equ
lbrfhm. This is most important element, and
one mat requires 10 DH Known ana also that ihe
air never presses more than fifteen pounds to the
square inch.
The next quality Of the air is elasticity Press
| it to make it occupy smaller space than it 9th
| erwse would, and then take awny the weight, and
| it comes back and occupies its original space
The lecturer then explained that III the air there
| were two gases one, oxygen, which is that part of
! the otmosphcr, by which chiefly we live, n which
is the one fifth part and the other ntogen, which
| is ~ uI ~ n DXNppn
life and combustion, md nitogen Restraints its
effects and dulls its opestions. The quantity of
air which person consumes depends IN II meas
urc on ones selfand by training can he made more
or less, The tailor and the shoe maker take lit
tie III comparison with the laborer, and the pub
lie speaker or singer, or those who cry commodi
ties for sale through the streets. A man in good
health makes eighteen respirations in II minute,&
! In twenty four hours consumes fifty -one hogs
| heads of mir. AS the oxygen which supports life
i is So small, we ought to be very particular how
we permit other gases TO mix with it and vitiate
| it. The blood when it enters the lungs is black,
| but when the oxygen is on it, it becomes red, and
sends it through the veins to impart life and ami
nation. This black blood is produced 10y carbon
and imparts the blackness which we see in the
face of persons who lose their lives by sltfocaton,
because the air was not allowed to reach the
lungs to- purify it. When we send eout the air
from the 'uugs,w do not send it in the same man
nor rs we inhaled it, for when eXhaled it is as
! deadly poison as arsenic or corrosive suhlmata.
The lecturer showed this by experiments, and fill
| led vase, it'll his own breath, in which IA ligh-
ted candle would not live. 1t was such air as Kill
! ed persons who went down into wells in the eoun-
try, or who died when pan of charcoal was pla-
! ced in room. The danger of taking impure
matter into the stomach had power to eject inn
! purties which the lungs had not. Besides the
impure air which we eXhale, there are $500 pores
| a nv Df he bpIy
and to body Of large size there $500 square
inches; and these multiplied make 100000 of
| pores. There is n sort of drainage pipe in the
body, which sends out matter we'll us gas, and
! this pipe is calculated at twenty eight miles long.
The particles of matter which are sent out and
which do not dissolve, are numerous that. in
China whore the houses low and great
many persons are in the habit of assembling in
| one room, IL has been discovered that, after ff-
teen or twenty years, these particles adhere to
the ceiling of the rooms, and the farmer will con
tract to put up n new ceiling if they are allowed
to take down the old one, SO valuable has it been
found for manure Scientific 4merjcdn.

SMALL NorE LAw-,Judge Hopkins of the
Abingdon district in late charge to a Grand
Jury, enforced the duty of obeying the law pro-

might be ATTENDED with some Inconvenience, That
It was proper to enforce the law, and especially

to obtain very generally throughout the State

ATTEMPTED AssAssINATIoN.-A yillainous at
tempt was made in Williamsburg, few nights
SINCE by some person or persons unknown, to as
sassinate policeman by the name of Lindsay.
His skull was horribly crushed by a blow from an
iron hinge. it is supposed, and his recovery is
very doubtful. He had been active in enforcing
the law in regard to tipping shops aud selling Ii.
quor TO negroes, and it is thought the attempt on
| his life was made by some enemy he has made
thereby The citizens of Williamson g held
public meeting and offered reward of $500 for
the detection of the felon, to which 800 is added
by the brother ofthe injured man.
