HUGENII VITA.
In the year 1689, he visited England for the third time.
The following year, he published two treatises, one on Light, the other on Gravity.
He was laboring over the Cosmotheoros The Celestial Worlds Discover'd under the press at the time of his death, although the edition was only begun.
He ended his life at The Hague on the eighth of June, 1695.
He bequeathed all his writings to the Library of the Academy of the Estates of Holland, which is in Leiden. He requested two men, distinguished mathematicians, Burcher de Volder, a celebrated Professor of Philosophy and Mathematics at that same Academy, and Bernhard Fullenius, a Professor at the Frisian Academy of Franeker, to select from his writings what could be committed to the press, to which request we owe the volume of posthumous works, published in the year 1700.
