fed to the birds. He asserts that this treatment suc- 

 ceeded completelj' within a few days. 



Some have obtained satisfactory results by adminis- 

 tering camjihor in the form of pills, the dose being one - 

 half to one grain twice a day. Others have succeeded 

 with sulphur, giving one to three grains at a dose. 



Those engaged in raising birds should depend rather 

 on prevention than cure. The value of a three-weeks- 

 old chicken is not sufficient to justify a great expendi- 

 ture of time in its treatment. The effort should be 

 made to place the young birds on uninfected ground, 

 or the runs should be kept thoroughly disinfected. On 

 the first appearance of the disease remove and isolate 

 the affected birds and take the necessary precautions to 

 secure the destruction of all the parasites they contain. 

 By such measures the propagation of the worm will be 

 prevented and the extension of the disease will be 

 avoided. 



SYNGAMUS BRONCHIALIS. 



A worm closely related to the Syngannis trachealis 

 has been described in Europe as affecting 3'oung ducks 

 and goslings. It is found in the finer bronchial tubes 

 preventing the ingress of air and causing death from 

 as])li3^xia. It sets up much irritation and even causes 

 croui)al pneumonia. The symptoms are similar to 

 those caused by the Syngannis trachealis, but more 

 violent, and sudden deaths due to obstruction of the 

 air tubes are common. This worm has been named 

 the Syngamus bronchialis, and is combated by the pre- 

 ventive measures and internal remedies recommended 

 for the Syngamus trachealis.
