88 CONCLUSION. 



latus and the Tcenia solium, was declared to be very sharply 

 defined ; the appearance of the former being supposed to be con- 

 fined to Switzerland,, Poland, and Russia ; but now, if the Taenia 

 solium were to show itself in these countries, it would not be a 

 matter of astonishment nor appear unworthy of belief, since, 

 through the importation of cattle infested with Cysticerci, from 

 countries where only the Tcenia solium is found, this tape-worm 

 may easily be introduced in its scolex form. 1 



After this statement of the history of the tape-worms, and of 

 the Cysticerci which stand in such close relationship with them, 

 I trust that I may have so strongly shaken the many false views 

 and prejudices so deeply rooted amongst physicians, veterinarians, 

 and economists, with regard to the origin, development, and pro- 

 pagation of these intestinal worms, that they may henceforth be 

 renounced as untenable. I have thereby not only the satisfaction 

 of having uprooted the very foundations of a chateau en Espagne, 

 filled with the most marvellous hypotheses, but of having erected 

 in its place a structure compacted of facts and based upon experi- 

 mental demonstrations, which throw a light upon a path hitherto 

 wrapped in profound obscurity, but which may now be profitably 

 followed. 



1 According to a written communication, for which I am indebted to Dr. Baumert, 

 during his stay in Neuchatel, the Cysticerci are almost unknown in pigs in the western 

 parts of Switzerland, viz., in Neuenburg, whilst all those pigs that are introduced there 

 from France are abundantly infested with them.
