Of political convulsions like the French Revolution we may probably say that they also are likely to be mitigated by the ghastly recollection of the ruin they cause, and by the remedy for. social unrest which the spread of liberal institutions offers. The worst effects of floods and droughts are now obviated by the great facilities for international traffic. Therefore, if we can conceive cholera, typhus, and all such diseases extirpated by sanitary science, the diseases that scourge immorality disappearing before a rigid police, and cures, such as are even now anticipated, actually discovered for consumption and cancer, perhaps even for diseases of the liver and kidneys, it will not be too much to say that the present expectation of life under healthy conditions would be more than doubled. Tennyson has alluded to the great stimulus hope would derive if we were
In lieu of many mortal flies, a race

It does not seem possible that we should ever attain to the thousand years, but there is perhaps nothing palpably unreasonable in assuming that ninety may be for some coming generation what seventy is in our own days; that the death-rate of children, which is one-third in Victoria for the very young of what it is for Austria, Italy, and Spain,[1] may be reduced very far below the healthiest average at present; and that for the ordinary
