Сторінка 340 - No one fact relative to the human species is more clearly ascertained, whether by general observation or actual proof, than that their fecundity varies in different communities and countries. The principle which effects this variation, without the necessity of those cruel and unnatural expedients so frequently adverted to, constitutes what I presume to call THE LAW OF POPULATION ; and that law may be thus briefly enunciated: — " THE PROLIFICNESS OF HUMAN BEINGS, OTHERWISE SIMILARLY CIRCUMSTANCED,...
Сторінка 645 - And there went forth a wind from the LORD, and brought quails from the sea, and let them fall by the camp, as it were a day's journey on this side, and as it were a day's journey on the other side, round about the camp, and as it were two cubits high upon the face of the earth.
Сторінка 617 - No flocks that range the valley free To slaughter I condemn; Taught by that Power that pities me, I learn to pity them.

It may safely be pronounced, therefore, that population, when unchecked, goes on doubling itself every twenty-five years, or increases in a geometrical ratio.
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...
Сторінка 601 - Through the animal and vegetable kingdoms Nature has scattered the seeds of life abroad with the most profuse and liberal hand; but has been comparatively sparing in the room and the nourishment necessary to rear them.
