at laft it recovered its ftrength, clung to the 
fides, climbed up to the top of the glafs ; and all 
was well again. I have fhifted another Anemone 
at once from 8° to 40°: but, inftead of leaving it 
only five minutes, I went on increafing the heat to 
46°, in order to obferve the effedt. The coat ap- 
peared to me to fwell out a little; at 50° it flill 
encreafed, and the animal died in confequence. 
I put feveral Anemonies, fome in, and fome 
without, water, under the recipient of an air-pump; 
and got the quickfilver of the barometer inclofed 
in it, to come down within an inch of the level. 
The animals did not feem to perceive the effedts 
of a vacuum , or an air fo much rarefied. They 
remained open, or in whatever ftate they happened 
to be when put in, and did not fwell out. When 
the air was let in again, and they were not in the 
water, I perceived no fhrinking at all in any of 
them. 
Thefe 
clle a repris vigueur, s’eft attachee, eta gagne le haut da vafe ; 
il n’y paroit plus. Da meme point de 8 degres j’ai fait paffer fu- 
bitement une autre anemone a 40, et au lieu de ne l’y laifler 
que cinq minutes, j’ai obferve ce qui fe pafleroit en conti- 
nuant de chauffer; a 46 degres la robe m’a paru fe bourfoufler 
un peu ; a 50 degres elle l'ecoit encore plus, de forte que i’ani- 
mal en eft mort. 
J’ai mis dans 1 ’eau, et fans eau, fous le recipient d’une ma- 
chine pneumatique plulieurs anemones, j’ai abailfe le mercure 
du barometre qui y etoit renferme, jufqu’a un pouce de fon 
niveau. Elies n’ont pas paru s’appercevoir de l’effet du vuide, 
ou d’un air fi fort rarefie : elles ont refte ouvertes, ou comme 
elles etoient, ne fe font point gonflees, et lorfque j’ai rendu 
l’air au recipient, et qu’elles n’etoient point dans l’eau je n’ai 
ajrpercu en elles aucun affaiffement.
