HELMINTHOLOGY. 



BY 



PROFESSOR C. TH. V. SIEBOLD, 



OF FREIBURG IN THE BRE18GATJ. 



A zootomical work by Owen (Lectures on the Compara- 

 tive Anatomy and Physiology of the Invertebrate Animals ;

 knowledge of the naturalist, but will be of great utility to 

 the physician, conveying, as they do to him, more correct 

 views respecting the so-called verminous diseases. A Report 

 on this subject, drawn up by Henle (Bericht liber die

 most warmly welcomed by the medical public. With the 

 same view also Valentin, has collected all the researches in
