Part 2

Newton has been the great glory of the Royal Society; and the Royal Society is justly proud of its most illustrious ornament. He joined it in January, 1674, when he was excused the ordinary payment of a shilling a week, "on account of his low circumstances as he represented." In 1703 he was elected to the presidential chair, which he continued to occupy until his death, in 1727. Characteristic mementoes of him are preserved among the Royal Society's treasures. There is a solar dial made by the boy Isaac, when, instead of studying his grammar and learning Virgil and Horace, he was busy making windmills and water-clocks. We fancy we see him going along the road to Grantham on a market day with the old servant whom his mother sent to take care of him, and then stopping by the wayside to watch the motions of a water-wheel, reflecting upon the mechanical principles involved in the simplest contrivances. It is pleasant, with our knowledge of what he afterward became, to sit down on the green bank by the river side, and to speculate upon the ignorance of the old servant who accompanied him, and of the farmers they saluted by the way, as to the illustrious destiny which awaited the widow's son who lived in the manor house of Woolsthorpe. The reflecting telescope, preserved along with the dial, was made by Newton in his thirtieth year, and reminds us of the deep mathematical studies he was then pursuing at Cambridge. The autograph MS. of the "Principia," also in the possession of the Royal Society, gives increased vividness to the picture of this extraordinary person in his study, solving mysterious problems, and suggesting others still more mysterious; and then the lock of silvery hair adds the last touch to fancy's picture--like a stroke of the pencil which, when a portrait is nearly complete, gives life and expression to the whole.

Newton was portly but not tall, his silvery locks were abundant without any baldness, and his eyes were sparkling and piercing, though perhaps they failed to indicate the profound genius which through them looked into the secrets of the universe. Wonderful humility blended with his intellectual greatness. To other men he seemed a spirit of higher rank, having almost superhuman faculties of mental vision, wont to soar into regions which the vulture's eye hath never seen; to himself he was but a boy playing with the shells on the seashore, while the ocean lay undiscovered before him. Others were taken up with what Newton accomplished, Newton was taken up with what remained to be done. So it is ever with the highest genius; the broader the range of view, the wider the horizon of mystery. He who understands more than others is conscious beyond others of what still remains to be understood.

Isaac Newton was born at Woolsthorpe, in Lincolnshire, on December 25, 1642, one year after the death of Galileo, and just as England was being plunged into the confusion and miseries of civil war. Strange to say, as a lad, at first he was inattentive to study; but being struck a severe blow by a school-fellow, he strangely retaliated by determining to get above him in the class, which he accomplished, and ere long became head of the school. His play hours were employed in mechanical contrivances, and a windmill in the course of erection on the Grantham road was an object of intense curiosity and a source of immense instruction. He soon had a windmill of his own, at the top of the house in which he lived. He had also a water-clock in his bedroom, and a mechanical carriage in the parlor, in which he could wheel himself. Paper kites and paper lanterns were his favorite toys. In the yard of the house he traced on a wall the movements of the sun by means of fixed pins; the contrivance received the name of "Isaac's dial," and was a standard of time to the country people in the neighborhood.

He entered Trinity College, Cambridge, June 5, 1660, just as England was astir with restoration festivities, and he soon devoted himself to mathematical studies. Euclid he took in at a glance, and afterward proceeded to master Descartes's geometry. Isaac Barrow, then Lucasian Professor of Mathematics, became his friend and tutor; and the pupil repaid the master's kind attention by services rendered to him in connection with his optical lectures. In 1669, Newton succeeded Barrow in his professorship. He rose to eminence in the university, and in 1688 was chosen its representative in the Convention parliament. In 1695 he was appointed Warden of the Mint, and was promoted to the Mastership in 1699. After his appointment to a government office he left Cambridge to reside in London, and occupied for a time a house in Jermyn Street. From 1710 till two years before his death he lived close to Leicester Square. Next door to Orange Street Chapel there stands an old house which has seen a good many changes, and is identified as the abode of Sir Isaac, who had been knighted by Queen Anne in 1705. We visited it many years ago. The part of the house most intimately associated with his name is the little observatory perched on the roof. We were permitted to ascend into that spot, to see it desecrated by its present use, for there we found a shoemaker busy at his toil. A glass cupola probably crowned the observatory in Newton's time, and evidently there was a window in each of the four walls. So here he looked out on the London of nearly a century and a half ago, hardly less crowded and smoky about the neighborhood than now. Overhead, where Newton turned his eyes with most interest, we know it was just the same; the same beautiful stars shining out on a cold winter's night, the same planets sailing along the same blue ocean, the same moon throwing its light over the same old city. What observations, keen and searching, what calculations, intricate and profound, what speculations, far-reaching and sublime, must there have been, when one of the most gifted of mortals from that spot looked out upon the heavens, and in thought went forth on voyages of discovery into the distant regions of the universe! At the calm, still hour of midnight, Sirius watching over the city of sleepers, Jupiter carrying his brilliant lamp along his ancient pathway, every one of the luminaries in the place appointed by Him who calleth them all by their names--there stood the thoughtful man, with his reflecting telescope, occupied with thoughts which we common mortals in vain endeavor to conjecture.

The first department in the field which Newton explored with characteristic success was the study of optics. Philosophers were busy with inquiries into the nature of light. It had been long believed that every colored ray is equally refracted when passing through a lens. Newton determined to analyze the prismatic hues. He made a hole in a window-shutter, and darkening the room, let in a portion of light, which he passed through a prism. The _white_ sunbeam formed a circular image on the opposite wall, but the _prismatic colors_ formed an image five times as long as it was broad. He was curious to know how this came to pass. Satisfied that the length of the image in the latter case did not arise from any irregularity in his glass, or from any differences in the incidence of light from different parts of the sun's disk, or from any curvature in the direction of the rays, he concluded, after thorough reflection, that light is not _homogeneous_, but that it consists of rays of diverse refrangibility. The red hue he saw was less refracted than the orange, the orange less refracted than the yellow, and the violet more than any of the rest. These important conclusions he applied in the construction of the first reflecting telescope ever used in the survey of the heavens, and an instrument is preserved in Trinity College Library bearing the inscription, "Invented by Sir Isaac Newton, and made with his own hands, 1671."

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.

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.

The first serious object of Peter's attention was to reform the army. In this he was materially assisted by a Swiss gentleman named Lefort; at whose suggestion he raised a company of fifty men, who were clothed and disciplined in the European manner, the Russian army at that time being little better than a tribe of Tartars. As soon as the little corps was formed, Peter caused himself to be enrolled in it as a private soldier. It is a remarkable trait in the character of the man, that he thought no condescension degrading which forwarded any of his ends. In the army he entered himself in the lowest rank, and performed successively the duties of every other; in the navy he went still further, for he insisted on performing the menial duties of the lowest cabin-boy, rising step by step, till he was qualified to rate as an able seaman. Nor was this done merely for the sake of singularity; he had resolved that every officer of the sea or land service should enter in the lowest rank of his profession, that he might obtain a practical knowledge of every task or manoeuvre which it was his duty to see properly executed; and he felt that his nobility might scarcely be brought to submit to what in their eyes would be a degradation, except by the personal example of the czar himself. Meanwhile he had not been negligent of the other arm of war; for a number of Dutch and Venetian workmen were employed in building gunboats and small ships of war at Voronitz, on the river Don, intended to secure the command of the Sea of Azof, and to assist in capturing the strong town of Azof, then held by the Turks. The possession of this place was of great importance, from its situation at the mouth of the Don, commanding access to the Mediterranean Sea. His first military attempts were accordingly directed against it, and he succeeded in taking it in 1696.

In the spring of the ensuing year, the empire being tranquil and the young czar's authority apparently established on a safe footing, he determined to travel into foreign countries, to view with his own eyes, and become personally and practically familiar with the arts and institutions of refined nations. There was a grotesqueness in his manner of executing this design, which has tended, more probably than even its real merit, to make it one of the common-places of history. Every child knows how the Czar of Muscovy worked in the dock-yard of Saardam in Holland, as a common carpenter. In most men this would have been affectation; and perhaps there was some tinge of that weakness in the earnestness with which Peter handled the axe, obeyed the officers of the dock-yard, and in all points of outward manners and appearance, put himself on a level with the shipwrights who were earning their daily bread. It seems, however, to have been the turn of Peter's mind always to begin at the beginning; a sound maxim, though here, perhaps, pushed beyond reasonable bounds. And his abode and occupations in Holland formed only part of an extensive plan. On quitting Russia he sent sixty young Russians to Venice and Leghorn to learn ship-building and navigation, and especially the construction and management of galleys moved by oars, which were so much used by the Venetian republic. Others he sent into Holland, with similar instructions; others into Germany, to study the art of war, and make themselves well acquainted with the discipline and tactics of the German troops. So that while his personal labor at Saardam may have been stimulated in part by affectation of singularity, in part, perhaps, by a love of bodily exertion common in men of his busy and ardent temper, it would be unjust not to give him credit for higher motives; such as the desire to become thoroughly acquainted with the art of ship-building, which he thought so important, and to set a good example of diligence to those whom he had sent out on a similar voyage of education.

Peter remained nine months in Holland, the greatest part of which he spent in the dock-yard of Saardam. He displayed unwearied zeal in seeking out and endeavoring to comprehend everything of interest in science and art, especially in visiting manufactories. In January, 1698, he sailed for London in an English man-of-war, sent out expressly to bring him over. His chief object was to perfect himself in the higher branches of ship-building. With this view he occupied Mr. Evelyn's house, adjoining the dock-yard of Deptford; and there remain in that gentleman's journal some curious notices of the manners of the czar and his household, which were of the least refined description. During his stay he showed the same earnestness in inquiring into all things connected with the maritime and commercial greatness of the country, as before in Holland; and he took away nearly five hundred persons in his suite, consisting of naval captains, pilots, gunners, surgeons, and workmen in various trades, especially those connected with the naval service. In England, without assuming his rank, he ceased to wear the attire and adopt the habits of a common workman; and he had frequent intercourse with William III., who is said to have conceived a strong liking for him, notwithstanding the uncouthness of his manners. Kneller painted a portrait of him for the king, which is said to have been a good likeness.

He left London in April, 1698, and proceeded to Vienna, principally to inspect the Austrian troops, then esteemed among the best in Europe. He had intended to visit Italy; but his return was hastened by the tidings of a dangerous insurrection having broken out, which, though suppressed, seemed to render a longer absence from the seat of government inexpedient. The insurgents were chiefly composed of the Russian soldiery, abetted by a large party who thought everything Russian good, and hated and dreaded the czar's innovating temper. Of those who had taken up arms, many were slain in battle; the rest, with many persons of more rank and consequence, suspected of being implicated in the revolt, were retained in prison until the czar himself should decide their fate. Numerous stories of his extravagant cruelties on this occasion have been told, which may safely be passed over as unworthy of credit. It is certain, however, that considerable severity was shown. This insurrection led to the complete remodelling of the Russian army, on the same plan which had already been partially adopted.

During the year 1699 the czar was chiefly occupied by civil reforms. According to his own account, as published in his journal, he regulated the press, caused translations to be published of various treatises on military and mechanical science and history; he founded a school for the navy; others for the study of the Latin, German, and other languages; he encouraged his subjects to cultivate foreign trade, which before they had absolutely been forbidden to do under pain of death; he altered the Russian calendar, in which the year began on September 1st, to agree in that point with the practice of other nations; he broke through the Oriental custom of not suffering women to mix in general society; and he paid sedulous attention to the improvement of his navy on the river Don. We have the testimony of Mr. Deane, an English ship-builder, that the czar had turned his manual labors to good account, who states in a letter to England, that "the czar has set up a ship of sixty guns, where he is both foreman and masterbuilder; and, not to flatter him, I'll assure your lordship it will be the best ship among them, and it is all from his own draught: how he framed her together, and how he made the moulds, and in so short a time as he did, is really wonderful."
