INDEX

It has been observed that the children of negro women, even by husbands 

of pure negro blood, are much lighter in color than usual if she has 

had a child by a white man previously. 

 

The same fact is observed in lower animals. In England, some years ago, 

a cross was effected between a male zebra and several young mares. Not 

only the hybrid colts resulting from this union, but all the colts 

afterward foaled by the same mares, from other horses, were striped 

like the zebra. 

 

In view of these facts, it is evident that the system of the woman, 

at least, may be profoundly affected in a similar manner by 

constitutional weaknesses, as well as by other individual 

peculiarities possessed by her husband. 

 

No person suffering with a contagious or infectious disease has any 

right to communicate the same to another. Indeed, it is the moral duty 

of every person so affected to do all in his power for the protection 

of others from the same cause of suffering. 

 

_2. Persons having a marked hereditary tendency to disease must not 

marry those having a similar tendency._ 

 

Every physician knows only too well the powerful influence of 

hereditary causes in determining the length of human life. Persons, 

one or both of whose parents have died of consumption, are very likely 

to die of the same disease, and frequently at about the same age. The 

children of such parents are commonly feeble and puny, and die early 

if they survive infancy. When both parents possess the consumptive 

tendency, the chance for life in the offspring is very poor indeed. 

The same may be said of those suffering with cancer, epilepsy, insanity, 

etc. Persons with a strong tendency to any one of the diseases mentioned 

should in no case marry. If there is but a slight morbid tendency, 

marriage may be admissible, but only with a partner possessing robust 

health. 

 

_3. Should cousins marry?_ 

 

Writers have devoted a good deal of attention to this subject, and we 

have been shown statistics, reports of imbecile asylums, etc., for the 

purpose of proving that the marriage of cousins results in the 

production of idiots, and other defectives; but the results of more 

careful examinations of the subject invalidate the views heretofore 

held, and it must be acknowledged that when both parties are healthy 

there is no more liability of mental incompetency in the children of 

cousins, than in the offspring of persons more remotely related. It 

must be added, however, that there are other reasons why the marriage 

of cousins is not to be generally recommended. Besides the fact that 

the feeling existing between cousins is often only that which is felt 

by brothers and sisters for each other, there is the still more 

important fact that on account of the blood relation, unions of this 

kind are more apt than others to bring together persons having similar 

morbid tendencies. 

 

_4. Persons having serious congenital deformities should not marry._ 

 

The reason for this rule is obvious. Persons suffering with serious 

congenital defects, as natural blindness, deafness, deformity of the
