Before the accession of Queen Victoria the 'industrial revolution,' the vast development of manufacturing made possible in the latter part of the eighteenth century by the introduction of coal and the steam engine, had rendered England the richest nation in the world, and the movement continued with steadily accelerating momentum throughout the period. Hand in hand with it went the increase of population from less than thirteen millions in England in 1825 to nearly three times as many at the end of the period. The introduction of the steam railway and the steamship, at the beginning of the period, in place of the lumbering stagecoach and the sailing vessel, broke up the old stagnant and stationary habits of life and increased the amount of travel at least a thousand times. The discovery of the electric telegraph in 1844 brought almost every important part of Europe, and eventually of the world, nearer to every town dweller than the nearest county had been in the eighteenth century; and the development of the modern newspaper out of the few feeble sheets of 1825 (dailies and weeklies in London, only weeklies elsewhere), carried full accounts of the doings of the whole world, in place of long-delayed fragmentary rumors, to every door within a few hours. No less striking was the progress in public health and the increase in human happiness due to the enormous advance in the sciences of medicine, surgery, and hygiene. Indeed these sciences in their modern form virtually began with the discovery of the facts of bacteriology about 1860, and the use of antiseptics fifteen years later, and not much earlier began the effective opposition to the frightful epidemics which had formerly been supposed to be dependent only on the will of Providence.
