London, Feb 3 (IANS) A dusty box full of textbooks found at the bottom of a cupboard in a school laboratory in Britain turned out to be 300-year-old works of Isaac Newton owned by the school's first principal.
The books were found in Newcastle-under-Lyme School, Staffordshire, the Daily Express reported.
The discovery was made by 16-year-old physics student Will Garside working on recording artefacts from around the school site.
The books contain Newton's Laws of Motion and an account of the principles of gravity spanning more than 1,000 pages.
The set of three volumes is believed to have been the property of the first headmaster, Francis Elliot Kitchener, who was at the school from 1874.
The school said it will not sell the books because of their historical importance.
The three books are named "Philosophiae Naturalis Principia Mathematica", Latin for mathematical principles of natural philosophy, and they were first published July 5, 1687.
Newton, born in 1642, died in 1727. His works were translated into English in 1728.
