Museum’s hidden natural treasures go on display

A descendant of Sir Hans Sloane, whose astonishing collections were the foundation of the Natural History Museum, has donated £2  million for a new gallery to showcase its highlights.

Among its 22 treasures — many of which will remain a secret until the opening — is a carved nautilus shell, pictured, which was one of Sir Hans’s favourite specimens. The physician and collector prized both the exquisite carving — to reveal its inner sheen — and the way the coil of the shell naturally follows the “golden ratio” used by Leonardo da Vinci to create proportions pleasing to the human eye.

Tate Greenhalgh, the museum’s interpretation developer, said the gallery would include many items often asked for by visitors but not on regular display, including John James Audubon’s illustrated Birds of America book. She said: “It showcases our most precious things all in one place.”

Earl Cadogan has already visited the gallery which bears his name before its official opening on Tuesday by the Duchess of Cambridge. Sir David Attenborough will be among the guests.

The Treasures Cadogan Gallery will open to the public next Friday, admission free.
