A company of _savans_ were seen in the visions of the night, busy with a new scientific invention. Earth, they argued, earth has her volcanoes, her burning exhalations; men have electric lights, fires, gas lamps, furnaces. These make up the world's proper illumination. The effect intended was, therefore, to darken the air we breathe, so that no rays from the upper sky should pass through it. The inventors hoped that a district, a country, nay, even a world, might thus be overshadowed by a gloom impervious to moon and stars by night, to sun by day; and the human eye see no changes, save those which the earth's activity, or human power and skill, might produce. Terrestrial and artificial alternations excepted, all was to be changeless as winter midnight--deep impenetrable darkness! It was seen slowly, very slowly, to descend. In thirty years the men of science hoped and purposed its perfection. Did those who had previously known the beautiful light of heaven, who had bathed and basked in the life-giving sunbeam, feel happy, or even calm, when they saw their children and children's children robbed of celestial glory and gladness? Yet there is one thing worse than a world without a sun--you know what I mean--Humanity without a GOD. POSTSCRIPT. The Lecturer purposely abstained from reading Professor Huxley's acute critique on Positivism until this Lecture had gone to press. He now strongly recommends his auditors to read No. viii. of the Lay Sermons. Should any reader find difficulties in pages 23-25 of the foregoing Lecture, he will do well to peruse Littré's "Auguste Comte et la Philosophie Positive," chapter iii., particularly pp. 42, 43.
