                                of fibres next make their appearance, the radiating & circular, which have not at 
first the sharp outline which they after-
wards acquire but still appear obscurely 
granular. As the tissue of these organs 
possesses nothing characteristic like that 
of the parts just described, the progressive 
changes which they undergo during the 
different periods of their formation can be 
but imperfectly distinguished; & hence 
no further description of them will be ne=
cessary. 
It has been observed in respect to 
the two sets of organs above described, that 
their size does not increase materially 
after once formed; exactly the reverse 
is the case with the part called the neck, 
also the quantity, though not the size of the 
laminated bodies which increase in 
number as the cavity of the latter increases 
in size. These bodies appear as soon as 
the hooklets & suckers, & they are as large 
when first formed as afterwards, but there 
are indications of the transverse wrinkles 
of the neck before either hooklets or suckers 
can be distinguished. See Plate 4. figs: 2 & 3.
The neck afterwards continues to grow, so 
that its relative length in respect to the 
ventral portion is an indication of the age 
of a Cysticercus.
It is probable that this part does not 
arrive at its full size until it is protruded, 
which I have never seen to be the case in 
any
