                                any animalcule which I have examined, & 
therefore, perhaps this is not effected until it 
quits its confined locality between the 
muscular fibres & gains access to the free 
surface of a mucous membrane - there, 
according to some physiologists to be farther 
developed into a higher form of entozoon. 
In the preceding observations on the 
development of the Cysticercus cellulosae, I 
have confined myself entirely to such facts 
as are sufficiently obvious & easy of verifi-
cation, as to leave no doubt of their general 
accuracy, also to those explanations of their 
meaning which appear to be almost self-
evident; & I might have concluded this 
paper had there not remained some con-
siderations entirely of a theoretical nature 
too important to be omitted.
It will be asked, how the Cysticercus 
in its earliest condition, such as I have 
described it, finds access to the interior 
of a primary fasciculus. Before attempt-
ing to answer this question I must observe 
that my description commences from a con=
dition of this entozoon so complete, that 
no one, on examining it with the microscope 
& comparing it with those forms in which 
the development is more advanced would 
doubt their perfect similarity. But this 
form though so low is very far from being 
the earliest indication of an abnormal state 
of the muscular fibres of all those animals 
which are infested
