THE T^NIA SOLIUM, 77 



numerous, more diversified, and more intense in 

 females than in males. 



The chief symptoms of taenia are : — Giddiness, 

 confused noises in the ears, impairment of vision, 

 itching at the nose and at the anus, increased flow of 

 saliva, disordered appetite, indigestion, colic, pains at 

 the epigastrium, and in other parts of the abdomen, 

 palpitation of the heart, syncope, the sensation of 

 some heavy substance in the abdomen which occa- 

 sionally changes its position, weariness and pains in 

 the limbs, and emaciation. 



In some patients the morbid phenomena, particu- 

 larly the peculiar sensation in the abdomen, the 

 anxious, restless state of mind, and the faintness, 

 come on during the day at regular periods, which 

 have an evident relation to the hours at which the 

 meals are taken, and which are removed after some 

 food has been swallowed. 



The abdominal pains which are caused by taenia, 

 and wliich constitute its most frequent symptom, are 

 similar sometimes to colic, sometimes to gastralgia ; 

 and in other cases they are of a vague, indefinable 

 character. They are situated in different parts of the 

 belly, and in the loins ; they are more or less severe, 

 and often sharp and intermittent, and are not ordi- 

 narily accompanied or followed by diarrhoea. 



The itching at the anus is also one of the most 

 common symptoms. In some instances it may be 

 attributed, like the itching at the nose, which is less 

 frequent, to sympathetic irritation ; but in the 

 majority of cases it is due to the irritation of the 

 mucous membrane of the lower part of the intestine 

 by the contact and movements of the cucurbitini.
