The various plans of treating the attacks of intestinal

The knowledge of the mode, or of the difierent 

 modes, of propagation of entozoa can alone furnish 

 the means of preventing their invasion of the body. 

 The recent progress of helminthology, by removing 

 the obscurity which attached to the origin of some 

 of these parasites, admits of some remarks being 

 made in this respect. 



The ignorance which exists as to the manner in 

 which the bothriocephalus is transmitted necessarily
