At the request of the Royal Society, he published in the "Transactions" an account of his optical discoveries, and proved that white light is a compound of seven prismatic colors.
Everybody is familiar with the story of Newton's watching the apple fall from the tree. The tradition is fondly cherished on the spot where the philosopher is said to have been struck by the fact. The law by which the apple falls, not the reason which underlies the law, formed the subject of Newton's reflections, and led to the grandest of modern discoveries. The unknown cause of the apple's descent is the unknown cause of the planet's motion. That was the truth, simple and grand, which he brought to light and inculcated on the world. He undertook long calculations which he expected would prove this theory, but they failed to give the desired result. He consequently for a time desisted from the inquiry and turned his attention to other subjects. The error in Newton's first calculation arose from his taking the radius of the earth according to the received notion that a degree measured sixty miles, whereas Picard had determined it to be sixty-nine and a half miles. This was mentioned at a meeting of the Royal Society in 1682, at which Newton was present. "It immediately struck him that the value of the earth's radius was the erroneous element in his first calculation. With a feverish interest in this result, little imagined by those present, he hurried home, resumed his calculation with the new value, and having proceeded some way in it, was so overpowered by nervous agitation at its anticipated result, that he was unable to go on, and requested a friend to finish it for him, when it came out, exactly establishing the inverse square as the true measure of the moon's gravitation, and thus furnishing the key to the whole system." Hence proceeded Newton's immortal work, the "Principia."
The sublimest conclusion which Newton drew from his cautious and successful investigations of the laws of nature is put, with his characteristic humility, in the form of a query: "These things being rightly described, does it not appear from the phenomena that there is a Being incorporeal, living, intelligent, omnipresent, who, in infinite space (as it were in His sensory), sees the things themselves intimately, and thoroughly perceives them, and comprehends them wholly by their immediate presence to Himself?"
Newton spent his last days in Kensington. "I was, Sunday night," says his nephew, "March 7, 1725, at Kensington, with Sir Isaac Newton in his lodgings, just after he was come out of a fit of the gout, which he had in both of his feet for the first time, in the eighty-third year of his age. He was better after it, and had his health clearer and memory stronger than I had known them for some years." A year later the same diarist says: "April 15, 1726. I passed the whole day with Sir Isaac Newton, at his lodgings, Orbell's Buildings, Kensington, which was the last time I saw him." The house was lately in existence, situated in what is called Bullingham Place, retaining, when we visited it, a mansion-like aspect, with a large garden and tall trees. There he died, March 20, 1727, having on the previous day been able to read the newspaper and to hold a long conversation with Dr. Mead.
His body was laid in state in the Jerusalem Chamber, and then buried in Westminster Abbey.[Back to Contents]
PETER THE GREAT
(1672-1725)
At the close of the sixteenth century, the dominions of Russia, or Muscovy, as it was then more generally called, were far thrown back from the more civilized nations of southern Europe, by the intervention of Lithuania, Livonia, and other provinces now incorporated in the Russian empire, but then belonging either to Sweden or Poland. The Czar of Muscovy, therefore, possessed no political weight in the affairs of Europe, and little intercourse existed between the court of Moscow and the more polished potentates whom it affected to despise as barbarians, even for some time after the accession of the reigning dynasty, the house of Romanoff, in 1613, and the establishment of a more regular government than had previously been known. We only read occasionally of embassies being sent to Moscow, in general for the purpose of arranging commercial relations. From this state of insignificance, Peter, the first Emperor of Russia, raised his country, by introducing into it the arts of peace, by establishing a well-organized and disciplined army in the place of a lawless body of tumultuous mutineers, by creating a navy, where scarce a merchant vessel existed before, and, as the natural result of these changes, by important conquests on both the Asiatic and European frontiers of his hereditary dominions. For these services his countrymen bestowed on him, yet living, the title of Great; and it is well deserved, whether we look to the magnitude of those services, the difficulty of carrying into effect his benevolent designs, which included nothing less than the remodelling a whole people, or the grasp of mind and the iron energy of will, which were necessary to conceive such projects and to overcome the difficulties which beset them. It will not vitiate his claim to the epithet that his manners were coarse and boisterous, his amusements often ludicrous and revolting to a polished taste; if that claim be questionable, it is because he who aspired to be the reformer of others was unable to control the violence of his own passions.
The Czar Alexis, Peter's father, was actuated by somewhat of the spirit which so distinguished the son. He endeavored to introduce the European discipline into his armies; he had it much at heart to turn the attention of the Russians to maritime pursuits; and he added the fine provinces of Plescow and Smolensko to his paternal dominions. At the death of Alexis, in 1677, Peter was but five years old. His eldest brother Theodore succeeded to the throne. Theodore died after a reign of five years, and named Peter his successor, passing over the second brother, Ivan, who was weak-minded. Their ambitious sister, Sophia, stirred the strelitzi, or native militia, to revolt in favor of Ivan, and Peter and his mother had to take refuge in the Troitski convent. This retreat being discovered, they were driven for protection to the church altar itself, where the religion or superstition of the wild soldiery saved the intended victims. We pass in silence over the remaining intrigues and insurrections which troubled the young czar's minority. It was not until the close of the year 1689, in the eighteenth year of his age, that he finally shook off the trammels of his ambitious sister, and assumed in reality, as well as in name, the direction of the state. How he had been qualified for this task by education does not clearly appear; but even setting aside the stories which attribute to his sister the detestable design of leading him into all sorts of excess, and especially drunkenness, with the hope of ruining both his constitution and intellect, it is probable that no pains whatever had been taken to form his intellect or manners for the station which he was to occupy. One of the few anecdotes told of his early life is, that being struck by the appearance of a boat on the river Yausa, which runs through Moscow, and noticing it to be of different construction from the flat-bottomed vessels commonly in use, he was led to inquire into the method of navigating it. It had been built for the Czar Alexis by a Dutchman, who was still in Moscow. He was immediately sent for; he rigged and repaired the boat, and under his guidance the young prince learned how to sail her, and soon grew passionately fond of his new amusement. He had five small vessels built at Plescow, on the lake Peipus; and not satisfied with this fresh-water navigation, hired a ship at Archangel, in which he made a voyage to the coast of Lapland. In these expeditions his love of sailing was nourished into a passion which lasted through life. He prided himself upon his practical skill as a seaman; and both at this time and afterward exposed himself and his friends to no small hazard by his rashness in following this favorite pursuit.
