150 VERMINOUS DISEASES. 



Authors speak of liydatids seen iu the cavity 

 of tlie thorax, in the substance of the heart, in 

 the superficies of the pericardium, (33) in the sto- 

 mach, in the intestines, ^34) in the mesentery, (35) in 

 the iiver,(3G) in the epiploon, 37) in the vesicula 

 fellis,(38) in the kidneys,(39) in the uterus, (40) in 

 the the placenta,(41) in the umbilical cord, (43) in 

 the testicles,(43) in the ovP4ries,(44) in the intersti- 

 ces of the muscles,(46) in fine, in almost every part 

 of the human body.(46) xlre all these hydatids, 

 truly vesicular? This question is not yet fully 

 elucidated or decided. If ICoelpin and Walther 

 liave concluded that for the most part hydatids 

 are a mass of vesicular worms, (47) Werner, an 

 accurate observer, has also made it appear,(48) that 

 small bladders of hydatids are formed of inorganic 

 substances, and consequently they cannot constitute 

 a separate auimal. In this view of the subject 

 Soemmering'^ s idea would be well founded, (49) in 

 regarding hydatids as real varices of the lymphatic 

 Tessels. It remains to be proved that the hydatids 



of hydatigeuous phthisis. He relates p. 24, that on opening the 

 body of a child of 5 years old, who died of this disease, he 

 found three hydatids in the lobes of the lungs : these hydatids 

 were of the solitary species ; two were on the left division at 

 some distance from each other ; they did not exceed the dinien- 

 sions of a hemp seed ; the third was in the right lobe, and was 

 as big as a large hazel-nut. 



We cannot admit with Dr. Bonafox, a sort of hydatige- 

 nous Phthisis, because hydatids are not produced by consump- 

 tion, but from general and local asthenia. F, Trs.
