The effect of the respiratory power
is modified by the degree of the
purity of the air. 1t has been abun-

land and Welsh, that the compost

able attitudes is identically the same
with that found at the level of the
low lands, but at lower levels there
may be great diversity in the consti-
tuition of the air as the result of de-
tectlve sanitation, or in badly venti-
lated apartments. In this connec-
tion we cannot refrain from referring
to the published statements regard
ing the purity of the air of elevated
sections. Such statements are merely
calculated to mlslead those who are

vanced in years, or whose lungs are
seriously diseased, should not visit
Colorado. 1t it requires from "two
weeks to four months" before a pa.
tient can become accIimated at our
western mountain resorts, it appears
like a dangerous proceeding TO make
the experiment. Two weeks or
four months, are all important
periods OF time in the existence of
persons suffering from pulmonary
diseases. Such cases are not suit

matization; and patients should Sc
