Immediate Source of Acquisition
After his death, Newton's manuscripts passed to his niece Catherine and her husband John Conduitt. In 1740 the Conduitt's daughter Catherine, married John Wallop, who became Viscount Lymington when his father was created first Earl of Portsmouth. Their son became the second earl, the manuscripts thus being inherited by succeeding generations of the Portsmouth family. In 1872, the fifth earl passed all the Newton manuscripts he possessed to the University of Cambridge, where a catalogue of the collection was made by a syndicate comprising the University scientists George Gabriel Stokes, John Couch Adams, Henry Richards Luard and George Downing Living (see 'Finding Aids')
