His majesty and council, indeed, took all imaginable care for their relief, by proclamation for the country to come in and refresh them with provisions. In the midst of all this calamity and confusion there was, I know not how, an alarm begun that the French and Dutch, with whom we are now in hostility, were not only landed, but even entering the city. There was in truth some days before great suspicion of these two nations joining; and now, that they had been the occasion of firing the town. This report did so terrify that on a sudden there was such an uproar and tumult that they ran from their goods, and, taking what weapons they could come at, they could not be stopped from falling on some of those nations whom they casually met, without sense or reason. The clamor and peril grew so excessive that it made the whole court amazed, and they did with infinite pains and great difficulty reduce and appease the people, sending troops of soldiers and guards to cause them to retire into the fields again, where they were watched all this night. I left them pretty quiet, and came home sufficiently weary and broken. Their spirits thus a little calmed, and the affright abated, they now began to repair into the suburbs about the city, where such as had friends or opportunity got shelter for the present, to which his majesty's proclamation also invited them. %DISCOVERY OF GRAVITATION% A.D. 1666 SIR DAVID BREWSTER Many admirers of Sir Isaac Newton have asserted that his was the most gigantic intellect ever bestowed on man. He discovered the law of gravitation, and by it explained all the broader phenomena of nature, such as the movements of the planets, the shape and revolution of the earth, the succession of the tides. Copernicus had asserted that the planets moved, Newton demonstrated it mathematically. His discoveries in optics were in his own time almost equally famous, while in his later life he shared with Leibnitz the honor of inventing the infinitesimal calculus, a method which lies at the root of all the intricate marvels of modern mathematical science. Newton should not, however, be regarded as an isolated phenomenon, a genius but for whom the world would have remained in darkness. His first flashing idea of gravitation deserves perhaps to be called an inspiration. But in all his other labors, experimental as well as mathematical, he was but following the spirit of the times. The love of science was abroad, and its infinite curiosity. Each of Newton's discoveries was claimed also by other men who had been working along similar lines. Of the dispute over the gravitation theory Sir David Brewster, the great authority for the career of Newton, gives some account. The controversy over the calculus was even more bitter and prolonged.
