Drawing and description of a fish (dolphin?) caught in Marseille on 28 November 1770.
With the note 'A Domino Grosson, admiratore domini Linei facta est Descriptio Massilia'.
Sent by Jacob Jonas Björnståhl to Carl Linnaeus, 30 November 1770 n.s., "The Linnaean correspondence", linnaeus.c18.net, letter L4426. Björnståhl writes to Linnaeus that 'a couple of days ago a very strange fish was caught outside the harbour of Marseilles. Grosson made a description in French and a sketch of it. Björnståhl asked him to make a copy for Linnaeus and to write the description in Latin. Linnaeus must excuse the result: Grosson is an expert in natural history but not in Latin grammar!'
