Note 12 — A REPLY TO THE ESSAY ON POPULATION BY THE REV. T. R. MALTHUS In a Series of Letters. To which are added, Extracts from the Essay, with Notes (continued 2)

I have here purposely left an opening for Mr. Malthus’s ingenuity. He will I hope take the hint and write another quarto volume to prove by anatomical and medical inquiries into the state of all countries, beginning at the north and ending at the south pole, that there is the same variation in the quantity and kind of food required by the human stomach in different climates and countries, as there is in the quantity of sexual indulgence.
