HISTORY OF ZOOPHYTOLOGY. 
de Jussieu and Guettard * proceeded, in the autumns of 1741 
and 1742, to different parts of the coasts of France with the 
view of examining their zoophytical productions ; and both were 
soon satisfied of the truth of the animal theory. Bernard de 
Jussieu in particular shewed that it was equally applicable to 
many zoophytes which Peyssonnel had not examined, and whose 
animalityhad not yet been suspected, viz. the flexible and delicate 
Sertularise, the Flustra, and the Alcyonium or Lobularia, the 
latter of which seems to have excited much astonishment by the 
protrusion of its thousands of polypes of a size large enough to 
be seen and examined at ease with the naked eye. f 
The memoir which Jussieu presented to the Academy of 
Sciences in Paris is short, but characterized by great distinct- 
ness and precision in the detail of his observations, and illus- 
trated with excellent figures ; — his aim being evidently not to 
entrap our blind assent by a declamatory display of the new 
wonders opened up in science, but to prove his conclusion to 
be the true one in the eye of reason and sobriety. He limits 
his descriptions and remarks to four species, viz, Alcyonium di- 
gitatum, Tubularia indivisa, Flustra foliacea, and Cellepora 
pumicosa, which seem to have been selected as examples of the 
more remarkable tribes, for it is evident that he had examined 
manymore, buthis observations on them were reserved for another 
memoir which, I believe, was never written. J — Reaumur’s ad- 
* Lamouroux speaks highly of the labours of this naturalist, whose attention 
seems to have been chiefly directed to fossil polypidoms and to sponges. — Corail.

f That Jussieu had ascertained the animality of the Sertulariadse is, I think, 
indisputable from the following passage. “ II s’en presentoit ensuite quantite 
de celles qu’on appelle Corallines, les unes pierreuses dans lesquelles je ne re- 
marquai rien, et les autres dont les tiges et les branches, et ce qui passoit pour 
feuilles, etoient d’une apparence membraneuse, dans lesquelles je decouvris que 
ce qu’on y prenoit pour feuilles disposees alternativement, ou dans un sens op- 
pose, n’etoit autre chose que de petits tuyaux contenant chacun un petit insecte.” 
— Mem. de l’Acad. Roy. des Sc. an. 1742. p. 292 — Reaumur is still more ex- 
plicit. : “ Apres avoir observe dans l’eau meme de la mer plusieurs especes deces 
productions si bien conformees a la maniere des plantes, il vit sortir des bouts de 
toutes leurs branches et de tous leurs noeuds, ou de toutes leurs articulations, 
de petits animaux qui, comme les polypes a panache d’eau douce, se donnoient 
tantot plus, tantot moins de mouvement, qui comme ceux-ci s’epanouissoient en
