into pills and administered to the affected birds. 

 Lucet has successfully treated verminous enteritis 

 caused by tapeworms and the heterakis.by giving in- 

 termittent doses of calomel, 1 -6 to '3 of a grain, and 

 mixing with the feed the heads of santonin, artemisia 

 vulgaris and wormwood. 



In treating heterakis infestation in pigeons, the 

 healthy should be separated from the diseased; the 

 walls, perches, ceilings, nests, floors and feeding and 

 watering vessels must be kept scrupulously clean and 

 frequently disinfected ; the grain upon which they are 

 fed should not be scattered over the ground but placed 

 in proper receptacles which are not likely to be con- 

 taminated with the excrement. It is well to mix ani- 

 seed, salt, and other substances appetizing to pigeons, 

 and also coarsely powdered areca nut, with the grain. 

 Each diseased pigeon may be given 1 -10 of a grain of 

 calomel worked up with soft bread or made into pills 

 with butter (Zurn). Some authors recommend feed- 

 ing peas which have been macerated for several hours 

 in a cold decoction of wormwood. The remedies 

 which have been used for heterakis in fowls are also 

 applicable to pigeons. 



No treatment is given for fowls affected with trema- 

 todes or flukes as these parasites so far as is known do 

 not affect the health of the birds which they infest. 



THE NODULAR T.-ENIASIS OF FOWLS. 



An intestinal disease of fowls, characterized by nod- 

 ules closely resembling tubercles in the walls of 

 the small intestine and colon, was described by 

 Moore, in 1895, as the result of investigations con- 

 ducted for the Bureau of Animal Industry. On 

 the serous surface of the intestine these nodules
