These are strong cases. But we have a still stronger case. 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 Herault. On the one side are the thirty-two departments from Cher to Gironde inclusive. On the other side are the forty-six departments from Herault 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 Mr 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-- 1st Table 2nd Table 3rd Table In the thirty-two departments in which there are from 86 to 132 people on the square mile....... 4210 4199 3760 In the forty-seven departments in which there are from 132 to 417 people on the square mile........ 4250 4224 3766 This fact is alone enough to decide the question. Yet it is only one of a crowd of similar facts. If the line between Mr Sadler's second and third division be drawn six departments lower down, the third and fourth divisions will, in all the tables, be above the second. If the line between the third and fourth divisions be drawn two departments lower down, the fourth division will be above the third in all the tables. If the line between the fourth and fifth division be drawn two departments lower down, the fifth will, in all the tables, be above the fourth, above the third, and even above the second. How, then, has Mr Sadler obtained his results? By packing solely. By placing in one compartment a district no larger than the Isle of Wight; in another, a district somewhat less than Yorkshire; in the third, a territory much larger than the island of Great Britain. By the same artifice it is that he has obtained from the census of England those delusive averages which he brings forward with the utmost ostentation in proof of his principle. We will examine the facts relating to England, as we have examined those relating to France.
