Leaving aside all question of the accuracy of the estimate of this particular treatment, it is easy to see that when a pestilence lies heavily on a nation, the numbers affected are so large that a proper or improper treatment may be capable of saving or of destroying many thousands of lives. By all means, then, let competitive methods be tested at hospitals on a sufficiently large scale to settle their relative merits.

The result clearly proved Regression; the mean Filial deviation was only one-third that of the parental one, and the experiments all concurred. The formula that expresses the descent from one generation of a people to the next, showed that the generations would be identical if this kind of Regression was allowed for.
How is it possible for a population to remain alike in its features, as a whole, during many successive generations, if the average produce of each couple resemble their parents? Their children are not alike but vary It is in the most unqualified manner that I object to pretensions of natural equality.
