Exhibit C 103—109. 43
“ Condition with regard to marriage and mortality, cases of c 103
death from tuberculosis,” after Weinberg, also confirms with regard
to tuberculosis the favourable influence of marriage on the health
of men. With women the mortality from tuberculosis up to the age
of 60 is lowest among the unmarried. Pregnancy and suckling act
here adversely, but by far the worst position is also held here by
widows and divorced women.
The advantage of marriage for the progeny is made evident in C 104-105
Figure C 104—“ mortality of illegitimate children in different European
states, and in Figure C 105 dealing with the “ survival of the
legitimate and illegitimate children in Berlin in 1885.” After five
years there are still alive more than 60% of the legitimate, but only
40% of the illegitimate children. The higher mortality of the latter
is by no means a purifying process of weeding, but the expression
of greater sickliness which permanently harms the surviving also.
The division of labour between man and wife, with reference to the
care of the offspring, is one of Nature’s institutions which is of the
greatest advantage for parents as well as children.
Inbreeding and the Crossing of Races. On the whole with man- C 106-107
k;nd inbreeding is viewed with fear, and iustily so, in view of our
customary carelessness with regard to the physical and mental con
ditions of those who contract marriage. If blood relations have
similar pathological conditions or pre-dispositions to illness or
degeneracy, the progeny which results from their union is endangered
to a particularly high degree. Our collection brings as an example
of this in Table C 106—the pedigree of the celebrated Don
Carlos. The bad inheritance of Johanna the Mad asserts itself to a
lesser degree yet quite perceptibly also in the children of Max. II.
Table C 107—the children of Maximilian and his cousin Maria of
Spain; undoubtedly the Emperor Rudolf II. was mentally diseased.
Also Charles V. and his son Philip II. were abnormal characters.
Blood relationship of the parents and health of the children. C 108
which v. d. Velden has prepared from Riffle’s family tables, also
speaks for the harmfulness of inbreeding. The offspring of blood
relations are emphatically weaker and sicklier than those of persons
related distantly or not at all.
The harm of inbreeding amongst the pathological is also illustrated C 109
by the large Table 222 (exhibited by Schiile). Pedigrees from wine
growing districts in the centre of Baden; against this it may be taken
as proved that inbreeding in itself between the healthy and fit
is not harmful. Animal breeders (as well as plant cultivators) make
