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
