About 1655 he made a small model of a steam carriage. This is described in the English edition of Huc's Christianity in China, in Muirhead's Life of James Watt, and in the Astronomia Europia, a work that is attributed to Verbiest, but was probably compiled from his works by another Jesuit priest and was published in Europe in 1689. The Verbiest model was for a four-wheeled carriage, on which an aeolipile was mounted with a pan of burning coals beneath it. A jet of steam from the aeolipile impinged upon the vanes of a wheel on a vertical axle, the lower end of the spindle being geared to the front axle. An additional wheel, larger than the supporting wheels, was mounted on an adjustable arm in a manner to adapt the vehicle to moving in a circular path. Another orifice in the aeolipile was fitted with a reed, so that the steam going through it imitated the song of a bird. ISAAC NEWTON Born at Woolsthorpe, Lincolnshire, England, December 25, 1642. Died at Kensington, March 20, 1727. Isaac Newton, who became one of the greatest mathematicians that the world ever knew, was the son of a farmer. He was educated at Trinity College, Cambridge, and in his early youth he mastered the principles of mathematics, as then known, and began original investigations to discover new methods. His great achievement was the discovery of the law of universal gravitation, but his genius was active in other directions, as the investigation of the nature of light, the construction of improved telescopes, and so on. He was a Member of Parliament in 1689 and 1701, and master of the mint, a lucrative position, from 1696 until the time of his death. In 1671 he was elected a member of the Royal Society, and was annually chosen to be its president, from 1703 until his death. Newton was one of the first Englishmen to conceive the idea of the propulsion of vehicles by the power of steam. Taking up for consideration Hero's hollow ball filled with water from which steam was generated by the outward application of heat, he added these conclusions: "We have a more sensible effect of the elasticity of vapors if the hole be made bigger and stopped, and then the ball be laid upon the fire till the water boils violently; after this, if the ball be set upon little wheels, so as to move easily upon a horizontal plane, and the hole be opened, the vapors will rush out violently one way, and the wheels and the ball at the same time will be carried the contrary way." Beyond this philosophical suggestion, however, Newton never went. The steam carriage attributed to him by some writers is merely an imaginative creation, by writer or artist, based upon the above proposition. VEGELIUS A professor at Jena, Saxony, in the seventeenth century, Vegelius constructed, in 1679, a mechanical horse, which was propelled by springs and cased in the skin of a real horse. This machine is said to have traveled four German miles an hour. ELIÉ RICHARD Born on the Island of Ré in 1645.
