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

                                for the production of cysticerci, (most probably 
the food had contained the germs of these 
animalcules) but had for a certain period 
been withdrawn from them, - so that all the 
younger animalcules had been as it were 
used up to produce the adult ones. Secondly, 
that those from which the second set had 
been taken had only been recently placed 
under such circumstances, & had re=
mained so circumstanced up to the time 
that they had been slaughtered, - & 
thirdly, that those from which the third 
set of specimens had been taken had 
both sometimes previously & immediately 
before they were slaughtered been placed 
under circumstances favourable for the 
production & development of cysticerci. 
Now as to the determination & discovery 
of what these favourable circumstances 
are, it would be necessary that the history 
of future animals, giving similar 
microscopic indications should be <u>most<\u> 
minutely inquired into, especially in 
relation to those different periods, & 
that the investigation of all these circum 
stances should be aided, &, tested, & directed 
by a series of the most careful experiments 
upon living animals, accompanied by exam=
inations of their food p, & all the circumstances 
under which they are placed, both during 
the period these animalcules are being 
developed in the muscles & afterwards.
