 tioned Charles II " to grant Chelsea College and the lands 

 belonging to it to the Royal Society." This was done but the 

 college was so out of repair that the Royal Society sold it in 

 1682. It was situated about three miles southwest of St. Paul's 

 Cathedral on the Thames but is no longer in existence. The 

 Society now meets in Burlington House, Piccadilly. 



32, 8. Newton. Sir Isaac Newton (1642-1727) was probably 

 the greatest mathematician that ever lived. His most famous 

 work, The Mathematical Principles of Natural Philosophy 

 (Philosophies Naturalis Principia Mathematica), the founda- 

 tion of modern astronomy, mechanics, and mathematics, was 

 accepted by the Royal Society in 1686 and published in the 

 summer of the following year.

 lications of the Royal Society, the other being The Proceedings of 

 the Royal Society. The first dates from 1665, the second from 

 1800. 



32, 28. Vesalius and . . . Harvey. Andreas Vesalius 

 (1514-1564) was a noted Belgian anatomist, his Seven Books on 

 the Human Body being epoch-making for his century. William 

 Harvey (1578-1657) was a famous English physiologist, in 

 whose Essay on the Motion of the Heart and the Blood (1628) 

 the circulation of the blood was first demonstrated. His last 

 publication was Essays on Birth (Exercitationes de Generatione, 

 1651).

 Mark iv, 31-32.

 whose speculations were useless and absurd.

 name was writ in water."
