Rare first edition novels by famous names such as Isaac Newton, Jane Austen and William Morris have gone under the hammer in Dorset.

Duke's of Dorchester Auctioneers said the entire collection raised nearly £1m, well above the estimated figure of £500,000.

Newton's Principia Mathematica, dated 1687, was sold to a New York collector for £90,000 including buyer's premium.

A first edition of Jane Austen's Pride and Prejudice was bought by a private Dorset collector for £22,000.

Meanwhile, a copy of William Morris's edition of Chaucer's Canterbury Tales went for £90,000 including buyer's premium.

Guy Schwinge, of Duke's of Dorchester Auctioneers, said: "The sale of 228 lots raised almost £1m.

"It's a blockbuster sale and quite a few world record prices have been broken."

Other sale highlights included a prized copy of Charles Darwin's The Origin of the Species and a first edition of Erhard Ratdolt's The Euclid.

The Origin of the Species, printed in 1859, sold for £42,000, while The Euclid, dated 1482, fetched £62,000.
