taken by the father in procreation, and Hippocrates, in combating this opinion, and contending that the child descended from both parents, seems to admit that it was a prevalent heresy.[581] Finally, it seems probable that the custom known under the name of “La Couvade”—that is, the odd rule, prevalent among several peoples in different parts of the world, requiring that the father, at the birth of his child, shall retire to bed for some time, and fast or abstain from certain kinds of food—implies some idea of relationship between the two.[582] Admitting, however, that there was a time when fatherhood, in the physiological sense of the term, was not discovered, I do not think that the preference given to the female line is due to this fact. If the denomination of children and the rules of succession really were in the first place dependent on ideas of consanguinity, it might be expected that a change with reference to the latter would be followed by a change in the former respect also. But the ties of blood have exercised a far less direct influence on the matter in question than is generally supposed, the system of “kinship through females only” being, properly speaking, quite different from what the words imply. There may be several reasons for naming children after the mother rather than after the father, apart from any consideration of relationship. Especially among savages, the tie between a mother and child is much stronger than that which binds a child to the father.[583] Not only has she given birth to it, but she has also for years been seen carrying it about at her breast. Moreover, in cases of separation, occurring frequently at lower stages of civilization, the infant children always follow the mother, and so, very often, do the children more advanced in years. Is it not natural, then, that they should keep the name of the mother rather than that of a father whom they scarcely know? Mr. Belt tells us that the men and women even of the christianised lower classes of Nicaragua often change their mates, and the children, in such cases remaining with the mother, take their surname from her.[584] According to Swann, the Creeks conferred the honour of a chief on the issue of the female line, because it was impossible to trace the right by the male issue, women only exceptionally having more than two children by the same father.[585] And touching the Khasias, one of the few tribes in India among whom the female line prevails, Dr. Hooker states that they have a very lax idea of marriage, divorce and exchange of wives being common and attended with no disgrace; “the son therefore often forgets his father’s name and person before he grows up, but becomes strongly attached to his mother.”[586]
