LAMARCK THE ZOOLOGIST 185 
The zodlogists who explored Egypt were Geoffroy 
St. Hilaire and Savigny. Those who visited the 
East, the South Seas, the East Indian archipel- 
ago, and other regions were Bruguiére, Olivier, 
Bory de St. Vincent, Péron, Lesueur, Quoy, Gaimard, 
Le Vaillant, Edoux, and Souleyet. The natural: re- 
sult was the enormous collections of the Jardin des 
Plantes, and consequently enlarged views regarding 
the number and distribution of species, and their re- 
lation to their environment. 
In Paris, about the time of Lamarck’s death, flour- 
ished also Savigny, who published his immortal works 
on the morphology of arthropods and of ascidians ; 
and Straus-Durckheim, whose splendidly fluerated 
volumes on the anatomy of the cockchafer and of the 
cat will never cease to be of value; and E. Geoffroy 
St. Hilaire, whose elaborate and classical works on 
vertebrate morphology, embryology, and compar- 
ative anatomy added so much to the prestige of 
French science. 
We may be sure that Lamarck did his own work 
without help from others, and gave full credit to 
those who, like Defrance or Bruguiére, aided or im- 
mediately preceded him. He probably was lacking 
in executive force, or in the art which Cuvier knew 
so well to practise, of enlisting young men to do the 
man birth and education. From 1823 to 1850 England fitted up 
and sent out exploring expeditions commanded by Beechey, Fitzroy, 
Belcher, Ross, Franklin, and Stanley, the naturalists of which were 
Bennett, Owen, Darwin, Adams, and Huxley. From Germany, less 
of amaritime country, at a later date, Humboldt, Spix, Prince Wied- 
Nieuwied, Natterer, Perty, and others made memorable exploring 
expeditions and journeys.
