Сторінка 21 - Hence marriages in America are more general, and more generally early than in Europe. And if it is reckoned there, that there is but one marriage per annum among one hundred persons, perhaps we may here reckon two ; and if in Europe they have but four births to a marriage (many of their marriages being late), we may here reckon eight, of which, if...
