From a slaudpoiul of symptomatologv, practically 

 nothing is known upon this subject. lu general, how 

 I'Vtir, it may bo slated that aquatic birds art' less af 

 fected by the presence of lapeworiiis than laud birds; 

 (hat young birds suffer more than old birds; and Ilia I, 

 although a fowl may harbor a small number of tape 

 worms without showing any ajipreciable effects, a 

 heavy infection injures the health and may result in 

 death, as has been abundantly demonstrated by epi 

 demies observed in ditTercnt jiarts of the world. II 

 has also been noticed that iioultry are more severely 

 infested in wet years than in dry years, and the general 

 application may be made that i)0ultry kept in damp 

 places will be more heavily infested than fowls ke|)l 

 in dry places. All of these slat("menls are general 

 principles of pai'asifolngy. 



Zflrn (1882, p. 17) gives (he synijitoms as follows; 



U' numerous tapeworms are presc'nt In the inteatine of young 

 or old fowls a more or less extensive Intestinal catarrh de- 

 velops, corresponding to the greater or less number of parasites 

 present. 



The Intestinal catarrh shows Itself, especially In chickens and 

 geese, as follows: The slcl^ animals become emaola'.ad, al- 

 though the appetite Is not especially dlstuTbed. At (Im-s (hn 

 appetite is even increased. The droppings are thin, contain 

 considerable yellow slime, and are passed In small quantities 

 but at short intervals. The poultry raiser must direct his at- 

 tention to these thin, slimy, and often bloody droppings, fin- 

 If any treatment against the tapeworms is to be undertaken, 

 this must be done as early as possible. In observing the drop- 

 pings It should be noticed whether tapeworm segments or eggs 

 are present, Tlic rgKs can h- s, en. .,r cuuisf. only witlj the
