Next are the _measures proposed for diminishing involuntary sterility_. Is involuntary sterility as frequent as it is supposed to be? Our respected master, Jules Rochard, was surprised to find two million sterile families recorded in the census reports. But the number does not appear excessive. We can not compare it with similar returns abroad, for France is the only country, except in the case of a few cities abroad, in which items of this kind are inquired into by the census takers. But, according to different gynæcologists--chiefly German--cited in the Academy of Medicine, the number of sterile families should be sixteen per cent. Now, this is the exact proportion found in France in the enumeration of 1896. The really surprising thing about the matter is not the number of sterile families, but the limited fecundity of the fertile families. There are other figures to show that absolute sterility is not the cause of the low rate of French natality. An inquiry respecting sterile families was made in 1856, at a time when French natality was a little higher than it is now, a comparison of the results of which with those of the enumeration of 1886 shows that the number of fruitful families had not diminished (83.6 per cent of the families having one or more children then, to 83.3 in 1886). The factor that has diminished is the fertility of the families. It is only necessary to cite the measures that have been suggested to counteract this supposed excessive sterility to make their inanity apparent. Among them are reform of the abuse of tobacco and alcohol and war upon syphilis. Do not these scourges exist among other nations than us? Nothing could be more salutary than to war upon them, but to connect their existence with the depopulation of France is a singular exaggeration of their importance. More than this, the physician of a benevolent institution in Paris has told me that the large families who resort to his dispensary nearly all have a drunkard at their head. The families that issue from such parents are not necessarily degenerate. This curious observation ought not certainly to make us partisans of drunkenness, but it demonstrates to us that the suppression of alcoholism is not what will restore French natality. Rather the contrary.
