STRUCTURE OF THE CYSTICERCUS CELLULOSE. 93 
It is maintained by the most eminent physiologists of the 
present day, that the Cysticercus of the pig is the “ scolex,” 
that is, the intermediate or arrested condition of the ie Tania, 
solium or tape-worm of man and other mammalia. 
The organization of the Cysticercus , as above described, 
goes far to establish this opinion, and direct experiments 
instituted upon dogs and other quadrupeds fed upon fresh 
“measled” pork seems to place it beyond a doubt. 
In the present case there was neither time nor opportunity 
to verify this theory by direct experiment. 
The history of the early condition and future development 
of the Cysticercus , the pathological and hygienic deductions 
to be drawn from the above observations, and their bearing 
upon the wholesomeness or otherwise of fresh, cured, or 
cooked c< measled” pork are questions which appertained to 
the branch of the inquiry entrusted to my colleagues ; I may, 
however, observe, that the microscopical examination here 
detailed would lead to the conclusion that the presence of 
the Cysticercus in the small numbers which occur in u slightly 
measled” pork does not appreciably affect the healthy con- 
dition of the muscular fibre, and that it is only when the 
numbers of this parasite are considerable that the fatty de- 
generation and watery condition of the muscles become 
apparent ; and as it further appears that the operations of 
curing, or cooking, destroy the assimilating powers of the 
cellules, and consequently the life of the Cysticercus , it 
would seem that no apprehension need be entertained of 
tape-worm following the use of “ measled” pork, provided 
the flesh be carefully cured or thoroughly cooked. —

ON THE STRUCTURE AND DEVELOPMENT OF THE 
CYSTICERCUS CELLULOSE, AS FOUND IN THE PIG. 
By George "Rainey, Esq. 
The Cysticercus celluloses , in its mature state, consists of 
two parts : one a small oval cyst, composed of a very thin 
membrane, rendered uneven on its external surface by 
minute rounded projections, and containing in its interior, 
granular matter, particles of oil, and a colourless fluid. This 
may be called its ventral portion. The other is folded in- 
wards, occupying the centre of the cyst just described, but
