62 NOTES ON 
sufficiently, the head is protruded, and the ten- 
tacula issue forth. The young one then sup- 
plies itself with food in the same manner as the 
parent (see e, figure 3). Until nearly matured 
and thrown off, there is an internal communi- 
cation between the parent and the young, and 
they seem to possess a sensation common to 
both, for, if one be disturbed and contract, the 
other immediately does the same. 
In the autumn it is said to produce eggs at 
the sides, in the same manner as the young are 
formed in summer. This I have been able to 
verify, though nearly all the polype that I have 
kept propagated in the way first described. 
The most remarkable fact relative to these 
creatures is, that they can be cut asunder, and 
each part will reproduce the deficient parts, and 
form a perfect animal. The best account I 
have seen of experiments on this subject is 
given by Baker in his “ Natural History of 
the Polype,’ before alluded to. His results, 
however, have been discredited by several in- 
telligent observers; I have therefore made some 
experiments on them myself, and find them 
agree with his statements in every material 
point: a description of the details of one may 
not be uninteresting.
