GUS system and the circulatory system.
However, the former is less responsive
to external stimulation, and the latter
is less vigorous in old age. The vital
processes conducted by the circulation,
respiration and metabolic changes in
the tissues are less active. There are
diminished adaptability Of the whole
system to changes in the environment
and less ability to meet the require
ments of emergencies, such as sudden
demands of muscular and mental strain.
The senile conditions and diseases are
numerous and obvious-in the first
place, weakened digestion and assimila-
tion. The weakened vigor Of the circula-
ton and glandular system necessarily
weakens the power Of eliminating
the excrementitious substances, which
gives rise to pernicious nutrition, and
that in turn is the cause Of the tendency
to develop malignant or benign growths
in different parts Of the body in old age.
The strong tendency to overeat and
underdrink, together with the natural
decline of functional power, gives rise
to condition of lithemia, which is the
prime cause of the majority Of deaths
in old age. In the healthy state that
great glandular furnace and chemical
laboratory, the liver, is capable of trans
forming an excess Of heterogeneous matter,
which may result from metabolism Of
tissue or exist in the food consumed,
into the highly soluble excrementitious
substance known as urea. This excre-
| ment is eliminated from the blood
mainly by the kidneys and to much
less extent by the skin.
Now, in old age, with the functional
power and natural vitality on the wane,
together with the strong tendency to
overlap this function of the liver, we
find this waste is not converted into
urea, but into uric or lithic acid, a com
paratively insoluble excrementitious and
toxic substance, which if it appears in
the blood in sufficient quantity and is
