weeks.

"These observations were not recorded after 1893. X. thinks that
in 1894 the intervals were longer, an opinion which is based on
the fact that for a period of six months he had no sexual
intercourse and no nightly emissions. The times during this six
months when he had the 'peculiar feeling,' the sensation was so
slight as to be scarcely noted. In 1895, the feeling seemed more
pronounced than ever before, and X. thinks that it may have
recurred as often as once a month. In 1896, 1897, and 1898, the
intervals, he thinks, lengthened--at times, he thought, wholly
disappeared. During 1899, while they did not recur often, when
they did come the sensation was pronounced, although the
emission was less common. There was a peculiar 'heavy' feeling
about the testicles, and a marked tendency towards erection of
the penis, especially at night-time (while sleeping). X. often
awoke to find a tense erection. Moreover, these feelings usually
continued a week.

"1. In general, X. is of the opinion that as he grows older these
intervals lengthen, though this inference is not based on
_recorded_ data.

"2. He notes that a discharge (through sexual intercourse or in
sleep) invariably brings the peculiar feeling to a close for the
time being.

"3. He notes that sexual intercourse _at the time_ stops it; but,
when there has been sexual intercourse within a week or ten days
of the time (based upon the observations of 1893), that it had no
tendency to check the feeling."

In another case, that of F.C., an Irish farmer, born in
Waterford, the data are still more meagre, though the periodicity
is stated to be very pronounced. He is chaste, steady, with
occasional lapses from strict sobriety, healthy and mentally
normal, living a regular open-air life, far from the artificial
stimuli of towns. The observations refer to a period when he was
from 20 to 27 years of age. During this period, nocturnal
emissions occurred at regular intervals of exactly a month. They
were ushered in by fits of irritability and depression, and
usually occurred in dreamless sleep. The discharges were abundant
and physically weakening, but they relieved the psychic symptoms,
though they occasioned mental distress, since F.C. is scrupulous
in a religious sense, and also apprehensive of bad constitutional
