Theological writers have always been puzzled to fix upon any very definite idea in regard to the geographical—so to speak—location of heaven. The Christian faith associates it as a final resting place for redeemed souls, and preachers have drawn from it the lesson that Eevelation, for wise reasons, had veiled the subj ect in obscurity. But science is progressive. It digs deep into the bowels of the earth, and soars away into regions of infinite space, so that at last we have a philosopher sufficiently bold who undertakes to remove our perplexity and solve all our doubts upon this sublime subject. Instead of being a matter of philosophic and Christian speculation we are now provided with a scientific solution of the whole difficulty by D. Mortimer, M. D.—not D. D. According to his theory " there is a vast globe or world far within from the surrounding photosphere of ethereal fire, which all denominate the sun, which globe is estimated to be at least five hundred thousand miles in diameter." Dr. Mortimer states that he has brought divine revelation to bear on this vast central globe, and is plainly convinced " that the globe thus discerned is the Heavenly Empire wherein the righteous from this earth find their future home." Not content to have made the discovery of the exact locality of " our heaven," the doctor has gone into a mathematical calculation of the number of minutes it requires for the spirit's flight from earth to this celestial abode, for all of which information doubting and believing souls will forever thank the learned doctor.
