SIR ISAAC NEWTON 



Royal Mint. In the latter part of his life Newton 

 published a "Chronology of Ancient Kingdoms," 

 that he had composed when at Cambridge, founded 

 on the astronomical observations of the ancients. 

 After his death were published a number of disserta- 

 tions upon the prophecies contained in the Scriptures, 

 which he considered embraced a mystical meaning. 

 Such conjectures were in accordance with the cus- 

 tom of many men of science of his time. No par- 

 ticular value is attached to these papers. Many other 

 of his writings of the same nature remain unpub- 

 lished. Newton never married. His health, after 

 recovering from the attack before named, was excel- 

 lent until he was eighty years old. He never required 

 the use of glasses to aid his vision and never even 

 lost a tooth. When eighty-five he suffered for 

 about twenty days from the presence of a calculus. 

 Two days before his death he lost consciousness. He 

 died March 20, 1727.* 



* The notice of Newton is mainly drawn from Jean Baptiste Biot's 

 exhaustive article in the Biog. Univ.- 2d Edit. T. 30.
