First Table. Second Table. Third Table. In the sixteen departments where there are from 68 to 107 people on a square mile 4188 4226 3780 In the sixteen departments where there are from 107 to 125 people on a square mile 4374 4332 3855 In the sixteen departments where there are from 134 to 125 people on a square mile 4484 4416 3914 {287}We will give another instance, if possible still more decisive. We will take the three departments of France which ought, on Mr. Sadler’s principle, to be the lowest in fecundity of all the eighty-five, saving only that in which Paris stands; and we will compare them with the three departments in which the fecundity ought, according to him, to be greater than in any other department of France, two only excepted. We will compare Bas Rhin, Rhone, and Nord, with Lozère, Landes, and Indre. In Lozère, Landes, and Indre, the population is from 68 to 84 on the square mile, or nearly so. In Bas Rhin, Rhone, and Nord, it is from 300 to 417 on the square mile. There cannot be a more overwhelming answer to Mr. Sadler’s theory than the table which we subjoin: The number of births to 1000 marriages is-- Take the whole of the third, fourth, and fifth divisions into which Mr. Sadler has portioned out the French departments. These three divisions make up almost the whole kingdom of France. They contain seventy-nine out of the eighty-five departments. Mr. Sadler has contrived to divide them in such a manner that, to a person who looks merely at his averages, the fecundity seems to diminish as the population thickens. We will separate them into two parts instead of three. We will draw the line between the department of Gironde and that of Hérault. On the one side are the thirty-two departments from Cher to Gironde inclusive. On the other side are the forty-six departments from Hérault to Nord inclusive. In all the departments of the former set, the population is under 132 on the square mile. In all the departments of the latter set, it is above 132 on the square mile. It is clear that, if there be one word of truth in MV. Sadler’s theory, the fecundity in the latter of these divisions must be very decidedly smaller than in the former. Is it so? It is, on the contrary, greater in all the three tables. We give the result. The number of births to 1000 marriages is-- [Illustration: 0294] In the thirty-two departments in whieh there are from 86 to 13.2 people on the square mile 4210 4199 3760 In the forty-seven departments in whieh there are from 132 to 41.7 people on the square mile....
