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

                                have not yet been able to ascertain. 
Their calibre is very irregular & some are much 
distended with blood corpuscles, & others have 
their coats so attenuated as not to be dis=
tinctly visible. The condition of these 
vessels is best seen in muscles so small 
as to allow of microscopic examination without 
the necessity of mechanical separation 
of their fibres as in the muscles moving 
the eye-ball especially near to the part 
where the muscular fibres are connected 
with the tendon. Although the presence 
of these abnormal particles of an ambiguous 
character in the interior of the primary 
fasciculi, & that of minute molecules in 
the blood vessels & their capillaries, with 
the attenuation of their coats may not fully 
answer the question proposed as to the precise 
manner in which the first indubitable 
forms of cysticerci find their way into 
the muscular fibres, still I think they 
may be considered as a near approach 
to a demonstration, that the more perfect 
forms of these entozoa, as represented in 
Plate 2 fig: 1. exist at first as mere ger=
minating particles & that they find their 
way to the muscular fibres through the 
medium of the blood.
<s>As to the origin of these particles ad=
mitting the probability of their being incipient 
states of a Cysticercus I have nothing to state 
but I think that the facts I have mentioned 
are<\s>
