Note 34 — Chapter III · Development of the Natural System under the Influence of the Dogma of the Constancy of Species. 1759-1850.

Bernard de Jussieu, born at Lyons in 1699, and at first a practising physician there, was by Vaillant’s intervention called to Paris, and after Vaillant’s death became Professor and Demonstrator at the Royal Garden. He and Peissonel were among the first who declared against the vegetable nature of the Corals. It is expressly stated in his Éloge (‘Histoire de l’Académie Royale des Sciences,’ Paris, 1777) that he founded his natural families on the Linnaean fragment. He died in 1777.
