lation of the abdomen,
never by wounds of the head. T. Claye Shaw, who terms the lust for blood
hemothymia, has written an interesting and suggestive paper ("A Prominent
Motive in Murder," _Lancet_, June 19, 1909) on the natural fascination of
blood. Blumroeder, in 1830, seems to have been the first who definitely
called attention to the connection between lust and blood.

_Annales Medico-Psychologiques_, July and August, 1893. D.S. Booth
(_Alienist and Neurologist_, Aug., 1906) describes the case of a man of
neurotic heredity who slightly stabbed a woman with a penknife when on his
way to a prostitute.

[105] Kiernan appears to have been the first to suggest the bearing of
these facts on sadism, which he would regard as the abnormal human form of
phenomena which may be found at the very beginning of animal life, as,
indeed, the survival or atavistic reappearance of a primitive sexual
cannibalism. See his "Psychological Aspects of the Sexual Appetite,"
_Alienist and Neurologist_, April, 1891, and "Responsibility in Sexual
Perversion," _Chicago Medical Recorder_, March, 1892. Penta has also
independently developed the conception of the biological basis of sadism
and other sexual perversions (_I Pervertimenti Sessuali_, 1893). It must
be added that, as Remy de Gourmont points out (_Promenades
Philosophiques_, 2d series, p. 273), this sexual cannibalism exerted by
the female may have, primarily, no erotic significance: "She eats him
because she is hungry and because when exhausted he is an easy prey."

[106] In the chapter entitled "Le Vol Nuptial" of his charming book on the
life of bees Maeterlinck has given an incomparable picture of the tragic
courtship of these insects.

Flagellation as a Typical Illustration of Algolagnia--Causes of Connection
between Sexual Emotion and Whipping--Physical Causes--Psychic Causes
probably more Important--The Varied Emotional Associations of
Whipping--Its Wide Prevalence.

The whole problem of love and pain, in its complementary sadistic and
masochistic aspects, is presented to us in connection with the pleasure
sometimes experienced in whipping, or in being whipped, or in witnessing
or thinking about scenes of whipping. The association of sexual emotion
with bloodshed is so extreme a perversion, it so swiftly sinks to phases
that are obviousl
