VENTILATION WHAT FOR AND HOW.

liajects are of SO much importance to tho house

why breathe at all: For one chief purpose-to
Mrm the animal heat that warns the body. The
bmeS Of every animal are the furnace; certain por
lions ol the food the carbon, i the fuel carried into
ihe furnace as part and by the circulation, of the
uIpod. And IS in all places where fuel is to be
burned You get no burning and no heat without the
ir. the oxygen Of the air. 50 YOU get in this
,nima fumace-lhc ungs--without that vital air
In "a hcalthy adult person the number of respira-
lions ner minute are about II; and nj each inspira-
lou about % cubic inches of air taken into the
lungs. or BOO cubic inches every minute; and aS one
tth ol this is pure oxygen, there must be GO cubic
inches of thi, vital air inhaled ever, minute to

common air $4,000 inches, or 5000 inches Of pure

From these data which are as certain as that 10

But lm~ want of oxygen is only half Of the evil.

that the certain effect ofbreahng is, first to con-
sumo large amount Of vital air, and secondly. to
rut IN it, place an equal amount of poisonous gas.
Hence the object of ventilation is two-fold-to admit

itucc the leath-giving carbonic acid.
