d forms
the scarlet red peroxide of iron, that gives the characteristic
color to the arterial blood. After this, as the blood is sent out
through the smaller arteries and capillaries, it again gathers carbon
and other impurities from the system, and becomes the dark, venous
blood, thus completing the whole change of color in the circulation.

As already mentioned, different articles of food have been divided
into the azotized and non-azotized, or those which contain nitrogen as
one of their constituents, and those which are nearly destitute of it.
Of these, according to Liebig, the azotized portions are simply to
supply the waste that is continually going on in the body, and promote
its growth in the early stages of existence, or, in other words, the
nutrient portion; while the sugar, starch, &c., are mainly of use in
the respiratory organs. The correctness of this view may be understood
from the fact, that the inhabitants in the colder regions of the earth
consume a much larger quantity of oil and fat than the residents of
hotter climates; and also those dwelling in the temperate zones can
eat with greater impunity a larger quantity of fat meats in the winter
than in the summer, there being then so much more demand for animal
heat than in the summer.

The suggestion of using the bellows in asphyxia, is from the

are the most practical, and best adapted to the wants of the
community.
