Between 1810 and 1811, amateur naturalist George Perry published 22 instalments of Arcana, a magazine dedicated to 'the most recent discovered objects in natural history' from around the world, including mammals, birds, reptiles, fish, molluscs and insects. This cleaned-up, chronologically ordered facsimile edition comprises the complete set of original texts, which combine scientific description with entertaining anecdotes, and all 84 exquisitely hand-coloured plates, as well as a collation and systematic review.
