On the Structure and Development of the Cysticercus cellulosae, as Found in the Pig, by George Rainey

                                these entozoa being very much 
diminished, their breadth increases 
rapidly, & they present globular pro=
jections extending out very irregularly 
from their sides, giving them a very 
irregular figure. See Plate 2, fig: 2 & 3. 
These projections gradually take on the 
form of those described on 
the ventral part of the perfect entozoon. 
The largest of the entozoa which I have 
seen in this stage is about 1/12 of an 
inch in length, & 1/40 in breadth.
The next facts requiring especial 
notice are those connected with 
that stage of development which takes 
place after the animalcule has 
become surrounded by an adven=
titious cyst.
The first indication of the forma-
tion of a cyst is, the turgescency 
of the capillaries, or some of the small=
er vessels in the vicinity of one or 
more entozoa. Granular bodies, 
exudation corpuscles, & fibres of different 
shapes next make their appearance. 
These at first obscure the entozoon & 
afterwards completely conceal it. When 
the cyst is first formed the animalcule 
can by a good light & careful examina=
tion be obscurely seen within it, & by 
dissection under the microscope it can 
be dislodged. See Plate 2. fig: 7. which 
is
