mpathetic
system and possibly the spinal cord, and which may be fairly laid under
suspicion of causing more structural modifications than are at present
recognized." H.H. Donaldson, _The Growth of the Brain_, p. 352.

[203] The state of menstruation is in many respects an approximation to
that of pregnancy; see, e.g., Edgar's _Practice of Obstetrics_, plates 6 6
and 7, showing the resemblance of the menstrual changes in the breasts and
the external sexual parts to the changes of pregnancy; cf. Havelock Ellis,
_Man and Woman_, fourth edition, Chapter XI, "The Functional Periodicity
of Woman."

[204] Thus the gypsies say of an unmarried woman who becomes pregnant,
"She has smelt the moon-flower"--a flower believed to grow on the
so-called moon-mountain and to possess the property of impregnating by its
smell. Ploss and Bartels, _Das Weib_, bd. I, Chapter XXVII.

[205] This was a sound instinct, for it is now recognized as an extremely
important part of puericulture that a woman should rest at all events
during the latter part of pregnancy; see, e.g., Pinard, _Gazette des
Hopitaux_, November 28, 1895, and _Annales de Gynecologie_, August, 1898.

recent book, Ellis Meredith's _Heart of My Heart_, is devoted to a
seemingly autobiographical account of a pregnant woman's emotions and
ideas. The relations of maternity to intellectual work have been carefully
and impartially investigated by Adele Gerhard and Helena Simon, who seem
to conclude that the conflict between the inevitable claims of maternity
and the scarcely less inevitable claims of the intellectual life cannot be
avoided.

HISTORIES OF SEXUAL DEVELOPMENT.

HISTORY I.--The following narrative has been written by a
university man trained in psychology:--

So far as I have been able to learn, none of my ancestors for at
least three generations have suffered from any nervous or mental
disease; and of those more remote I can learn nothing at all. It
appears probable, then, that any peculiarities of my own sexual
development must be explained by reference to the somewhat
peculiar environment.

I was the first child and was, naturally, somewhat spoiled--a
process which tended to increase
