ars there has been some tendency
for this climax to be thrown towards the middle of the week, but,
on the whole, Wednesday is the point of lowest frequency.

In another case, the subject, A.N., who has spent nearly all his
life in the State of Indiana, has kept a record of sexual
manifestations between the ages of 30 and 34. The data, which
cover four years, have not been sent to me in a form which
enables the possibility of a monthly curve to be estimated, but
A.N., who has himself arranged the data on a lunar monthly basis,
considers that a monthly curve is thus revealed. "My memoranda,"
he writes, "show that discharges occur most frequently on the
first, second, and third days after new moon. There is also
another period on the fourteenth and fifteenth, which might
indicate a semi-lunar rhythm. The days of minimum discharge are
the seventh, eighth, twenty-second, and twenty-third." It may be
added that the yearly average of ecbolic manifestations, varying
between 50 and 55, comes out as 52, or exactly one per week.

A weekly periodicity is very definitely shown by A.N.'s data.
Sunday once more stands at the head of the week as regards
frequency, in this case very decisively. The figures are as follows:--

Sun. Mon. Tues. Wed. Thurs. Fri. Sat.
48 21 24 35 28 26 27

In another case which has reached me from the United States, the
data are slighter, but deserve note, as the subject is a trained
psychologist, and I quote the case in his own words. Here, it
will be seen, there appears to be a tendency for the ecbolic
cycle to cover a period of about six weeks. In this case, also,
there is a tendency for the climax to occur about Saturday or
Sunday. "X. is 38 years old, unmarried, fair health, pretty good
heredity; university trained, and engaged in academic pursuits.
He thinks he may have completed puberty at about 13, though he
has no proof that he was in the full possession of his sex-powers
until he was 15 years 3 months old (when he had his first
emission). His sex life has been normal. He masturbated somewhat
when he slept with other boys (or men) during early manhood, but
not to excess.

"During the autumn of 1889 (when 28 years of age) he observed
that at certain times he had an itching feeling about the
testicles; th
