carried on through
many generations by the very sex that, by reason of the heavy monthly
losses of blood and of the expenditure of energies, required by
pregnancy, child-birth and nursing, has its physique heavily taxed.

[134] "Men of genius are, as a rule, of inferior size and massive brain.
These are also the leading features of the child, and the general facial
expression as well as the temperament of such men recall the
child."--Dr. Havelock Ellis, "Husband and Wife."

[135] The corporal weights are taken from Taupinard's "Anthropologie."

[136] If, with the authority quoted by Delaunay, we assume 11 kilograms
as the difference in weight between men and women, we would have found
35 to 70 grams.

[138] Quatrefages found the proportion to be slightly larger with woman
than with men. Thurman found the reverse, just as L. Manouvrier.

[140] Dr. Havelock Ellis furnishes a number of proofs of this fact in
his frequently quoted book. According thereto, woman, among wild and
half-wild people, is not only equal to man in physical strength and size
of body, but she is partly superior. On the other side, Ellis agrees
with others that, in consequence of our progress in civilization, the
difference in the capacity of the skull of the two sexes has steadily

[141] This is a discovery, first made by Karl Marx, and classically
demonstrated by him in his works, especially in "Capital." The
Communistic Manifesto, that appeared in 1848, and was composed by K.
Marx and Frederick Engels, is grounded upon this fundamental principle,
and must be considered, to this day, as the norm for all agitational
work, and the most excellent of all.

of Civilization in England."

[143] Ziegler, quoted above, denies that such is the meaning of
Virchow's argument. His own quotation of Virchow's argument, however,
confirms the interpretation. Virchow said: "Now, only picture to
yourselves _how the theory of the descent of man presents itself in the
head of a Socialist_! (Laughter.) Yes, gentlemen, that may seem funny to
some; it is, however, a serious matter, and I hope that the theory of
the descent of man _may not bring upon us all the horrors that similar
theories have actually brought upon our neighboring country. At any
