its slender quadrangels appear at a distance, to any philosophic spectators that knew about the amount of human interests confided to that army, and the hopes for Christendom that even then were trembling in the balance! Such a disproportion, it seems, might exist, in the case of a ghostly war, between the harvest of possible results and the slender band of reapers that were to gather it. And there was even a worse peril than any analogous one that has been proved to exist at Waterloo. A British surgeon, indeed, in a work of two octavo volumes, has endeavored to show that a conspiracy was traced at Waterloo, between two or three foreign regiments, for kindling a panic in the heat of battle, by flight, and by a sustained blowing up of tumbrils, under the miserable purpose of shaking the British steadiness. But the evidences are not clear; whereas my brother insisted that the presence of sham men, distributed extensively amongst the human race, and meditating treason against us all, had been demonstrated to the satisfaction of all true philosophers. Who were these shams and make- believe men? They were, in fact, people that had been dead for centuries, but that, for reasons best known to themselves, had returned to this upper earth, walked about amongst us, and were undistinguishable, except by the most learned of necromancers, from authentic men of flesh and blood. I mention this for the sake of illustrating the fact, of which the reader will find a singular instance in the foot note attached, that the same crazes are everlastingly revolving upon men. [2]

This hypothesis, however, like a thousand others, when it happened that they engaged no durable sympathy from his nursery audience, he did not pursue. For some time he turned his thoughts to philosophy, and read lectures to us every night upon some branch or other of physics. This undertaking arose upon some one of us envying or admiring flies for their power of walking upon the ceiling.
