THE HUMAN INTESTINE. 73 



was resorted to of nourishing the little patients with 

 raw beef. Most of the children who were subjected 

 to this mode of alimentation recovered ; but it was 

 soon ascertained that several of them had become 

 affected with taenia. 



From the preceding accounts it will be seen that 

 in a country where the taenia is common, those 

 persons who abstain from raw meat are alone 

 free from the attacks of that entozoon ; whilst in 

 another country, where taenia was scarcely known 

 previously, those only who eat uncooked flesh were 

 affected by this worm, and this latter result occurred 

 in young children in whom the taenia solium is 

 always more rare than in adults. 



It has been advanced by many writers that the 

 cysticercus found in the cellular tissue is converted 

 into the taenia sohum in the human intestine, but, as 

 Dr. Davaine observes, the cysticercus is not found in 

 beef although it is very common in pork. 



Hence Dr. Davaine further remarks, that it must 

 be concluded that if beef which does not contain the 

 cysticercus propagates the taenia, and if this worm is 

 sometimes present in persons who do not eat pork 

 (the Jews, for instance),^ the cysticercus celhilosae is 

 not the scolex, or head of the taenia solium, or else 

 that, at least, the taenia possesses some other mode of 

 propagation. 



^ Cases of tsenia are more frequent amongst the Jews than is 

 usually supposed. At the Metropolitan Free Hospital, which is 

 situated near Hounsditch and other parts of London inhabited 

 by members of this persuasion, and where a large number of the 

 poorer Jews apply for medical relief, I have frequently had 

 opportunities of verifying this fact.
