Note 8 — Domesticated Natives—Origin—Character

The Spanish Government strove in vain against natural law to counteract physical conditions by favouring mixed marriages,8 but Nature overcomes manʼs law, and climatic influence forces its conditions on the half-breed. Indeed, were it not for new supplies of extraneous blood infusion, European characteristics would, in time, become indiscernible among the masses. Even on Europeans themselves, in defiance of their own volition, the new physical conditions and the influence of climate on their mental and physical organisms are perceptible after two or three decades of yearsʼ residence in the mid-tropics.
