ACler a time other symptoms develop. The sick animals 

 become dull and listless, remain apart from the rest of the 

 flock; the feathers are ruffled and the wings drop, the appe- 

 tite is lost and the birds allow themselves to be easily caught. 

 Although it was stated that in the beginning of the trouble 

 the appetite is not disturbed, the sick animals develop an in- 

 tense thirst for cold water. When it rains they run under the 

 eaves in order to catch water, and in -winter are eager for Ice 

 water. 



At reading this some experienced poultry raisers will probably 

 reply that many chickens which are not sick are fond of very 

 cold water. The d'l-oppings are also thicker or thinner ac- 

 cording to the food. Both of these facts are known to me 

 (Zurn). At the same time I look with suspicion of tapeworms 

 upon every chicken which shows an especial thirst for cold 

 water: and as for the droppings, the fowls infected with tape- 

 worms have droppings mixed with mucus and blood, and pass 

 their excrements much oftener than other fowls do. 



The intestinal catarrh often ends fatally. 



Upon post-mortem the body is seen to be thin and anaemic. 

 The intestine generally contains no food, the mucosa is soft and 

 hyperaemic and covered with reddish yellow, more or less thick, 

 purulent mucus. According to Hertwig epileptic attacks are 

 frequently noticed in chickens affected with intestinal worms. 



The diagnosis by s\iuptoms seems to me very uucer- 

 taiu, :md although the symptoms deeribed by Ziini 

 sorvo as au iudicatiou of the disease, they ran not be 

 taken as prtxif. The diagnosis by hunting in (he 

 droppings for segments of the parasite is less satis- 

 factory than would be supposed, for it is not rare to 

 liud chickens badly infested with tapeworms when it 

 has been impossible to discover segments in the man 

 lire. This method is rendered doubly uncertain Ih' 

 cause the color of the segments is about the same as 

 the urine in the faeces. Microscopic examination of the 

 faeces for eggs is quite a certain (hough not pi>sitive 

 methiMi for diagnosis of tapeworm disease of poultry, 

 but it is thoroughly iiupracticabli' for the fanner to 

 aileiuin ii. The best method for the fanner t.i follow
