when it began to float, I faw plainly the Anemo- 
nies were quite detached from the Tides, becaufe' 
their body turned round loofe, with the ice, 
though their bafls had remained exactly in the 
fame fituation they were in before. Mr. Reaumur s 
thermometer being in my room, at two degrees 
above the freezing point, or o, thefe animals gave 
fome fign of life; and the 8th, the thermometer 
being at 3 \ they opened ; while the Anemonies, 
which were in other glatTes, and had not been ex- 
pofed to a greater cold than that of one degree 
above froft, did not open yet; and I generally ob- 
ferved they only opened at 5 0 of the thermometer. 
May it in confequence be fuppofed that thofe Ane- 
monies, which had been frozen in the ice, were lefs 
affected with a cold at 3 § than the others ?

elle devint flotante, j’eus lieu d’apercevoir que les anemones 
avoient cede d’etre attachees aux parcis du vai’e par leur bate, 
parcequ’eiles tournoient avec la glace, quoique leur bate eut 
abfolument demeure dans le rremc etat ou elles etoient aupa- 
ravant. Le thermometre de Mr. de Reaumur etant dans men 
cabinet a dtux degres de dilatation, ces animaux donnerent 
quelques fignes de vie, et le huit le thermometre etant a 3 i 
s’ouvrirent tandis que celles des autres vafes qui n’avoient point 
eprouve de froid plus grand qu’un degre de dilatation ne s'ou- 
vroient pas encore. Car j’ai remarque qu’elles ne s'ouvrent, 
a parler gencralement, que lorfque le tliermometre parvient 
a cinq degres. Celles qui ont ete enfermees dans la glace au- 
roient-elle* par comparaifon trouve la temperature de trois de- 
j*r€s et demi plus douce que ne la trouroient les autres l
