THE CYSTICERCUS TEL^ CELLULOSE. 191 



According to the cases which have been collected, 

 the parts of the human body in which cysticerci have 

 been most frequently observed are : — 1. The inter- 

 muscular areolar tissue of the body and of the 

 extremities ; 2. The brain ; and 3. The eye. The 

 spleen and the kidneys appear to be exempt from 

 the cysticercus telae cellulosae, and the liver is also 

 very rarely invaded by this entozoon. 



Similarly to the hydatids, cysticerci have a ten- 

 dency to dissemination throughout the body, and 

 they may often be seen in several organs, both 

 superficial and deep, in the same individual. It is a 

 remarkable fact that these two genera of vesicular 

 worms have, to some extent, an inverse tendency in 

 their distribution ; hydatids are common in the Hver, 

 in the lungs, and in the abdominal viscera ; the 

 cysticerci are, on the contrary, rare in these organs, 

 but are frequent in the parietes of the body, in the 

 limbs, in the brain, and in the eye, which parts are 

 very seldom invaded by hydatids. 



The cysticercus found in Man has been observed in 

 difiPerent countries and climates. It does not appear 

 to be more often present in one sex than in the 

 other ; and it has been seen in children not less 

 frequently than iq adults. According to Kudolphi, 

 vesicular worms are more common in persons of a 

 leucophlegmatic diathesis than in others. 



Yeterinary College, Edinburgh, stated that 3 per cent, of the 

 pigs in Ireland are " measly," owing to improper management. As 

 the cysticercus telae cellulosse is now generally supposed to be 

 converted into tape-worm, after it has found its way into the 

 human intestines, the serious ill effects which result from the 

 use of the flesh of these diseased animals as an article of food 

 can scarcely be sufficiently estimated.
