I have always slept when I wanted rest, and almost at will." After spending several successive days and nights without sleep, in preparation for a decisive conflict, he has been known repeatedly to fall asleep in the midst of the uproar and horror of the field of battle, and when the balls of the enemy were sweeping the eminence upon which he stood. "Nature has her rights," said he, "and will not be defrauded with impunity. I feel more cool to receive the reports which are brought to me, and to give fresh orders when awaking in this manner from a transient slumber." While in Milan, one morning, just as he had mounted his horse, a dragoon presented himself before him, bearing dispatches of great importance. Napoleon read them upon the saddle; and, giving a verbal answer, told the courier to take it back with all possible dispatch. "I have no horse," the man replied, "the one I rode, in consequence of forced speed, fell dead at the gate of your palace." "Take mine then," rejoined Napoleon, instantly alighting. The man hesitated to mount the magnificent charger of the general-in-chief. "You think him too fine an animal," said Napoleon, "and too splendidly caparisoned. Never mind, comrade, there is nothing too magnificent for a French soldier." Incidents like this, perpetually occurring, were narrated, with all conceivable embellishments, around the camp-fires, and they conferred upon the young general a degree of popularity almost amounting to adoration. [Illustration: NAPOLEON AND THE COURIER.] The lofty intellectual character of Napoleon was also developed at the same time, in the midst of all the cares, perplexities, and perils of these most terrible conflicts, in a letter publicly addressed to Oriani, the celebrated mathematician. "Hitherto," he writes, "the learned in Italy have not enjoyed the consideration to which they were entitled. They lived secluded in their libraries, too happy if they could escape the persecution of kings and priests. It is so no longer. Religious inquisition and despotic power are at an end. Thought is free in Italy. I invite the literary and the scientific to consult together and propose to me their ideas on the subject of giving new life and vigor to the fine arts and sciences. All who desire to visit France will be received with distinction by the government. The citizens of France have more pride in enrolling among their citizens a skillful mathematician, a painter of reputation, a distinguished man in any class of letters, than in adding to their territories a large and wealthy city."
