in cases where the Cysticerci have taken up their temporary 

 residence in the brain, they are usually found, post mortem, in the 

 grey cortical or peripheral substance of the cerebrum. The 

 particulars of such a case are given in my ' Entozoa ' where the 

 victim suffered from epi- 

 leptic fits due to the pre- 

 sence of numerous Cysti- 

 cerci (fig. 24) . The patient 

 was under Mr Hulke's care. 

 As regards infection by 

 the adult worm it is not 

 alone sufficient that we 

 avoid underdone meat, as

careful to have our sausages 



well cooked. Under ordinary circumstances, we are safe for the 

 following reasons : No respectable butcher will knowingly 

 supply us with pork or with sausages which are measled. Even 

 in the case of underdone meats, in whatever way prepared, it is 

 usually only a small portion which is unaffected by cooking. 

 As we have seen a temperature of 140 Fahr. is sufficient to 

 kill the Cysticerci. 



The successful rearing of pork measles by experimentation 

 with the eggs of T. solium has been accomplished by many 

 helminthologists, amongst whom may be particularised Van 

 Beneden, Leuckart, Kiichenmeister, Haubner, Gerlach, and 

 Baillet. The converse experiment of rearing the adult worm 

 from the Cysticercus was first successfully undertaken by 

 Kiichenmeister on a condemned criminal; Leuckart, Humbert, 

 and others having repeated this method with more or less 

 success. 



The dangers arising from infection by swallowing the larval 

 worms or six-hooked embryos are not easily avoided. Our 

 flesh, like pork, thus becomes measled, although certainly 

 not to the spawn-like extent so often seen in the lower 

 animals. A single measle is sufficient to prove fatal ; and 

 this humiliating contingency, moreover, is one which we can 

 never be absolutely certain of avoiding. We become the 

 " host " or bearer of the measle by swallowing the fully-developed 

 eggs of the Ttema solium. This we may do directly by hand- 

 ling fresh tapeworms, whose eggs, being concealed under our
