he second volume Lamarck gives a tabular view on a page
by itself (p. 463), showing his conception of the origin of the
different groups of animals. This is the first phylogeny or genealogical
tree ever published.

The next innovation made by Lamarck in the _Extrait du Cours de
Zoologie_, in 1812, was not a happy one. In this work he distributed the
fourteen classes of the animal kingdom into three groups, which he named
_Animaux Apathiques_, _Sensibles_, and _Intelligens_. In this
physiologico-psychological base for a classification he unwisely
departed from his usual more solid foundation of anatomical structure,
and the results were worthless. He, however, repeats it in his great
work, _Histoire naturelle des Animaux sans Vertebres_ (1815-1822).

The sponges were by Cuvier, and also by Lamarck, accorded a position
among the Polypes, near Alcyonium, which represents the latter's
_Polypiers empates_; and it is interesting to notice that, for many
years remaining among the Protozoa, meanwhile even by Agassiz regarded
as vegetables, they were by Haeckel restored to a position among the
Coelenterates, though for over twenty years they have by some American
zooelogists been more correctly regarded as a separate phylum.[124]
Lamarck also separated the seals and morses from the cetacea. Adopting
his idea, Cuvier referred the seals to an order of carnivora.

Another interesting matter, to which Professor Lacaze-Duthiers has
called attention in his interesting letter on p. 77, is the position
assigned _Lucernaria_ among his _Radiaires molasses_ near wh
