First appearance of an importent paper in animal physiology, as Reamur here, as the first biologist observes the regenration of the extremities and other parts of the body of crayfish.
"Reamur showed that crustaceans replace their lost limbs, a fact until then disputed."(Garrison & Morton No. 301).
"Réaumur was among the greatest naturalists of his or any age. In the breadth and range of his researches, in the patient detail of his observations, and in the brilliant ingenuity of his experiments, it would be difficult to name his equal. Thomas Henry Huxley has compared his favourably with Darwin."(DSB)
