He came now to announce to us the completion of his “ Essay on the Pericyclical Motions of the Earth’s Axis ,” and the precession of the equinoctial points. If an old Roman of the period of the Republic had returned to life, and talked of the impending election of some laurel-crowned consul, or of the last battle with Mithridates, his ideas would not have been more alien to the times, than the conversation of Merrival. Man, no longer with an appetite for sympathy, clothed his thoughts in visible signs; nor were there any readers left: while each one, having thrown away his sword with opposing shield alone, awaited the plague, Merrival talked of the state of mankind six thousand years hence. He might with equal interest to us, have added a commentary, to describe the unknown and unimaginable lineaments of the creatures, who would then occupy the vacated dwelling of mankind. We had not the heart to undeceive the poor old man; and at the moment I came in, he was reading parts of his book to Idris, asking what answer could be given to this or that position.
