Each sense presents its share--one sense more, another less. A person may have received a large number of impressions on the organ of vision--a painter, for instance--and may have stored away a wealth of artistic knowledge, yet the sense of hearing may be exceedingly poor in the number of impressions received. Such an individual would be rich in artistic ideas but comparatively poor in musical ideas. So it is with all the special senses. Each sense receives impressions on its own account. It has its own special nervous center, and these special centers again are closely connected with the great mass of brain matter. Collectively they have for their function, to receive impressions, retain them, store them away, recollect them, and reproduce them by articulate sound, or to recognize them. In this process then we have the formation of idea, memory, thought; recollection is the endeavor to call back, or form a figure of, an object once already perceived--felt by the senses. CHAPTER X. MOSES.--THE CONFIRMATION OF THE IDEA OF GOD. We will here sketch the military career of Moses. We omit the early incidents of the life of Moses--his childhood, his growth, his education--and begin with his active life. "And the occasion he laid hold of was this: The Ethiopians, who are next neighbors to the Egyptians, made an inroad into their country, which they seized upon, and carried off the effects of the Egyptians, who in their rage, fought against them, and revenged the affronts they had received from them; but being overcome in battle some of them were slain, and the rest ran away in a shameful manner, and by that means saved themselves, whereupon the Ethiopians followed after them in the pursuit, and thinking that it would be an act of cowardice if they did not subdue all Egypt, they went on to subdue the rest with greater vehemence; and when they had tasted the sweets of the country, they never left off the prosecution of the war; and as the nearest parts had not courage enough at first to fight with them, they proceeded as far as Memphis, and the sea itself, while not one of the cities was able to oppose them. The Egyptians, under this sad oppression, betook themselves to their oracles and prophecies" (Josephus, Ch. X). Moses thereupon was appointed general of the Egyptian army against the Ethiopians, and conquered them in the following manner:
