Can anyone help?

Plymouth City Museum and Art Gallery are currently undertaking a large project on a collection previously owned by Sir John St. Aubyn, the 5th Baronet (1758 to 1839). Currently, there is much interest in the ‘missing’ elements of the mineral collection and the journey to their respective resting places. After his death, Sir John St. Aubyn’s collection was split by the mineral dealer Isaiah Deck (1792-1853), and although an extensive collection was arranged for the Civil Military Library at Devonport (now at the main Plymouth City Museum), the remaining minerals were auctioned.
As part of the project, Plymouth City Museum and Art Gallery are trying to locate other specimens from Sir John’s mineral collection. The wish is to authenticate and photograph every specimen both in the museum and in other collections so that an online digital database can be created. If you can help, please contact the Natural History St. Aubyn project assistant, 01752 034774 - www.plymouthmuseum.gov.uk
