I am aware that this Parasite 
has been found in various other animals 
besides the Pig, also that it occasionally 
infests the Human subject, but as I have 
not had the opportunity of examining it in 
the latter, & as my opportunities of investigating 
its structure & development in the former 
have been very abundant, I shall confine 
my observations to this Entozoon as it 
occurs in the Pig.
The Cysticercus in its developed state 
is found chiefly in the ordinary muscles 
lodged in the cellular intervals between 
the fibres, also in the surface of the muscles 
immediately beneath their  fascial invest 
ment. They infest the heart in as great 
abundance as other muscles composed 
of striped fibres, where they are situated, 
some in the substance of the walls of 
the auricles & ventricles, others directly be
neath the pericardium between it & the
