The larger and better known Jardin d'Acclimatation in the Bois de Boulogne is owned and conducted by a private company.
The original axolotls, from the vicinity of Mexico City, it is believed, arrived at the Jardin d'Acclimatation, Paris, late in 1863.
Six specimens (five males and one female) were given by the Societe d'Acclimatation to Professor A.
Soon after their arrival at the Jardin d'Acclimatation, some of the axolotls spawned, but the eggs, not having been removed from the aquarium, were devoured by its occupants.
The first specimens exhibited in the London Zoological Gardens, in August 1864, were probably part of the original stock received from Mexico by the Societe d'Acclimatation, but do not appear to have bred.
It has been recommended by C. Darwin, and at one of the early meetings of the Societe Zoologique d'Acclimatation, at Paris, Isodore Geoffroy St Hilaire insisted that it was the only method by which acclimatization was possible.
