Mr. Ray having continued Minor Fellow whilst Bache- 

 lor of Arts, was (according to the custom of the college) 

 chosen Major Fellow, when of Master's standing. After 

 which, on October 1st, 1651, he was chosen the Greek 

 lecturer of the college; and on October 1st, 1653, he was 

 made mathematical lecturer ; and after that, on October 

 2d, 1655, humanity reader. 



After this, when of greater standing, he was chosen 

 into the offices of the college, and was made Prselector 

 Primarius, October 1st, 1657, and Junior Dean, October 

 2d, 1658 ; and lastly, twice College Steward, being sworn 

 into that office December 26th, 1659, and December 

 16th, 1660. 



During this time of Mr. Ray's being in the University, 



was placed first in the Charterhouse School, and then at Felstead in Essex. 

 He was entered at Trinity CoUege in 1645, was made scholar of his coUege 

 in 1667, B.A. in 1648, feHow in 1649, M.A. in 1652, Ad eundem at Oxford in 

 1653, B.D. in 1661, and D.J), by mandate in 1670. He had intended study- 

 ing physic when he first went to college ; but having changed his mind, he 

 commenced theology. Theology led him to study chronology, and chronology 

 astronomy, and astronomy mathematics. Trom 1655 to 1659, he travelled 

 on the Continent. On his return in 1660, he was chosen Greek professor at 

 Cambridge, and in 1662 Gresham professor of geometry. This last he re- 

 signed in 1663, having been appomted to the Lucasian professorship by 

 Mr. Lucas on its institution. This also he resigned in favour of Isaac 

 Newton, who was then twenty-seven years of age, and whom Barrow thought 

 a young man of great promise. In 1672 he was appointed master of 

 Trinity College, and laid the foundation of the library of that college. He 

 died on the 4th of May, 1677, having achieved a great reputation for a man 

 of so few years. " He was low of stature, lean, of a pale complexion, and 

 negligent of his dress to a fault." "Being invited to preach for Dr. 

 Wilkms," says one of his biographers, " in a parish church in London, his 

 appearance, which was that of an apprentice, drove the whole of the congre- 

 gation awa;^, except a few persons, among whom was Richard Baxter, the 

 nonconformist, who declared afterwards that he could have sat all day to 

 hear him." He was remarkable for preaching very long sermons. The 

 principal works of Barrow are as follow : — ' EucHdis Elementa,' Cambridge 

 1655 ; translated, London 1660. 'Euclidis Data,' Cambridge 1657. 'Lec- 

 tiones Opticse xviii,' London 1669. ' Lectiones Geometricae xii,' London 

 1670. After his death, his theological works and other writings were collected 

 together, and published by Dr. TiUotson, then Dean of Canterbury, accom- 

 panied with the life of Barrow, by Abraham HOI. The reputation which 

 Barrow obtained during his life has not been sustained since his death, but 

 he must stiU be regarded as taking a high position as a mathematician and a 

 theologian. Although Ray and Barrow were so intimately associated in 

 early hfe, the tendency of their genius led them to opposite pursuits ; and 

 thus we find little further notice of Barrow in the Life of Ray.
