THE BOTHRIOCEPHALTJS LATUS. 81 



been recorded in which two or more bothriocephali 

 have been expelled from the same individual ; and, 

 in the province of Nordbotten, in Sweden, where it 

 is endemic, this worm seldom exists singly, according 

 to Huss. 



A frequent symptom of the taenia, namely, the 

 itching at the anus, is not usually caused by the 

 bothriocephalus ; for, although it may, in the case of 

 the latter worm, be produced sympathetically, like 

 the itching at the nose, it is much less shown than 

 the almost constant irritation which is dependent 

 upon the movements of the cucurbitini, when the 

 patient is affected with taenia. 



The symptoms which especially denote the exist- 

 ence of the bothriocephalus are, according to Odier, 

 of Geneva, whose opportunities of observation were 

 very extensive, a tumid state of various parts of the 

 abdomen, irregular evacuations, nausea, vertigo, pal- 

 pitation of the heart, convulsive crying and sobbing 

 during the night, cardialgia, and fainting. 



In the province of Nordbotten, Huss states that 

 the symptoms of bothriocephalus generally consist in 

 an unpleasant sensation of suction at the epigastrium, 

 especially when the patient is fasting, flatulent gur- 

 glings of the abdomen, and pain and tension around 

 the orbits. 



The duration of the bothriocephalus does not 

 appear to be less than that of the taenia. Bremser 

 records a case of this parasite which came under his 

 notice, at Vienna, in a Swiss who had left his native 

 country thirty years previously.
