Precisely the same phenomenon is to be found in the cancer-mortality
of women. Each ten-year period of life exacts its own proportion,
with an increasing death-rate out of proportion to the increase of
population.

Another fact, attainable only by the study of English statistics, is
the singular regularity with which malignant disease selects different
parts of the body year after year. If proclivity to this mysterious
ailment were a matter of chance, or dependent upon the irregular
action of certain forces, we should certainly fail to find such
uniformity, or such approach to uniformity, as exists. One year, for
instance, there would be, let us say, a preponderance of attacks upon
the skin; another year the digestive organs would be the principal
sufferers; a third year the joints and muscles would be chiefly
involved. The actual experience proves that we are subject here to
forces of incalculable stress, which nevertheless press steadily and
uniformly upon humanity, where the habits and environment are the
same. In the year 1901, for example, of the total number of fatal
cases among men, the seat of the disease was the stomach in a little
over 21 per cent. of the total number of cases. In 1910 the
proportion was also 21 per cent. During the ten years 1901-1910, of
the total mortality, the stomach was the organ involved in but a
fraction over 21 PER CENT. OF THE TOTAL CASES.

Is cancer increasing? This is a question of vast importance to the
human race. That in proportion to total population more die from the
disease to-day than twenty or thrity years ago, is a fact about which
there can be no doubt. Dr. Stevenson, in the Repo
