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

                                disarranging them, or disturbing their position 
by manipulation. Secondly, because the 
material of which they are composed is so 
dissimilar in appearance to that forming 
the adjacent tissue, & so characteristic that 
it cannot be confounded with the structures 
in their immediate vicinity. Thirdly, because 
at one view in a favourable specimen, 
hooklets can be seen in every stage of their 
formation, from the first grouping together 
of the masses of formative particles to the 
blending of them into perfect organs, & 
lastly, because it is not as if a mere 
thread of tissue were formed amongst 
other thread somewhat different in ap=
pearance, as a fibre of elastic tissue for in=
stance in a mass of connective sub-
stance, but the part which is here examined is a perfect organ, & one, too 
which possesses a regular arrangement 
of parts connected together with order & 
remarkable regularity. So that under 
such circumstances, if these organs had 
been preceded by nucleated cells & these 
cells had been transformed into hooklets, 
neither these cells, nor their several stages 
of transformation could have escaped 
detection.
The parts next to be noticed are the suckers. 
Indications of these are visible as soon as the 
hooklets. They appear as four circular spaces 
presenting a granular aspect about the 
size of perfectly formed suckers. The two sets 
of fibres
