l *‘° interior portion of tlie stomach and the month was 
01 course prevented, yet instead of emaciating and dying of 
j* .'trophy, the animal had availed itself of what undoubtedly 
la d been a very untoward accident, to increase its enjoyments 
ar |d its chances of double fare. A new mouth, furnished 
5'th two rows of numerous tenlacula was opened on what 
been the base, and led to the under stomach : the indi- 
r "mal had indeed become a sort of Siamese twin, but with 
■raster intimacy and extent in its union.’’ This case also 
. mstrates the power these creatures have of sustaining 
Juries of the most formidable kind, with apparent impunity, 
which is exceeded only by the Hydra. They have 
f <en divided longitudinally and transversely, and the sepa- 
j' lte d portions have either again united or become developed 
lto separate animals. On two occasions I have met with 
j® s «lts similar to those described by the Abbe Dicquemare, 
a ' tng divided transversely several specimens of the common 
r l,e mone (A. Mesembryanthemum) in such a manner that 
n v thing taken in at the month passes out at the truncated 
’’’dace below ; but the cut surface closed in a few 
t ° to retain 
. 'daenla were formed, presenting the curious spectacle of an 
a n ! m al taking food at both extremities. If in taking the 
f ln 'al from its situation it be very much mutilated, it soon 
jr Sains its former state, and if a portion be separated, it will 
s fluently be developed into another polype. It has been 
} that if the base be torn the animal dies; an observation 
a a» unable to confirm and have good reason to donbt. If 
p - Portion of an actinia be injured or destroyed, the animal 
<£? * r> wer of replacing it. This power of repro- 
j s < j. ,n g lost parts, however, is not confined to Zoophytes, but

Batrachian reptiles. 
i Q 1 “e manner iu which the water is taken in and expelled 
kilcl - Actiniae is not yet settled. Professor Jones says it is 
in a few days 
a new mouth and

Hi !( | las repeatedly noticed the water entering by the mouth, 
« 0(( ^ have on many occasions seen the same thing; perhaps 
also enters by the small openings distributed over the 
t*,. and through which the white threads are sometimes

W i | 1 tl '. 1 y through the tentacula; if the animal be pressed, it
