amarck's death, flourished also Savigny,
who published his immortal works on the morphology of arthropods and of
ascidians; and Straus-Durckheim, whose splendidly illustrated 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 comparative 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 Bruguiere, aided or
immediately 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 drudgery or render material aid, and then, in some cases,
neglecting to give them proper credit.

The first memoir or paper published on a zooelogical subject by Lamarck
was a modest one on shells, which appeared in 1792 in the _Journal
d'Histoire naturelle_, the editors of which were Lamarck, Bruguiere,
Olivier, Hauey, and Pelletier. This paper was a review of an excellent
memoir by Bruguiere, who preceded Lamarck in the work of dismemberment
of the Linnaean genera. His next paper was on four new species of Helix.
To this _Journal_, of which only two volumes were published, Cuvier
contributed his first paper--namely, on some new species of "Cloportes"
(Oniscus, a genus of terrestrial crustacea or "pill-bugs"); this was
followed by his second memoir on the anatomy of the limpet, his next
article being descriptions of two species of flies from his collection
of insects.[120] Seven years later Lamarck gave some account of the
genera of cuttlefishes. His first general memoir was a prodromus of a
new classification of shells (1799).

Meanwhile Lamarck's knowledge of shells and corals was utilized by
Cuvier in his _Tableau elementaire_, published in 1798, who acknowledges
in the preface that in the exposition of the genera of shells he has
been powerfully seconded, while he indicated to him (Cuvier) a part of
the subgenera of corals and alcyonarians, and adds, "I have received
great aid from the examination of his collection." Also he acknowledges
that he had been greatly aided (_puissamment seconde_) by Lamarck, who
had even indicated the most of the subdivisions established in his
_Tableau elementaire_ for the insects (Blainville, _l. c._, p. 129), and
he also accepted his genera of cuttlefishes
