taken with the food and water or are inhaled in the 

 form of dust. 



Symptoms in the early stages are not noticeable and 

 at the best are very unreliable. About the first that 

 will be noticed is drowsiness and weakness; the bird 

 will not follow the flock; breathing will become difficult; 

 the patient may utter cries, especially during expira- 

 tion, but the throat, upon examination will be found 

 healthy; great thirst and often little or no appetite; 

 there is rapid emaciation; a fetid diarrhoea may set in 

 and prove fatal in from one to six or eight weeks. 



Treatment must be principally fumigating and 

 hygienic, although internal remedies are also indicated. 

 The affected birds should be removed from the flock. 



Tar fumes are especially valuable, or turpentine 

 poured on a hot brick will be found a good way to 

 fumigate. Care must be taken that the fumes are 

 not sufficiently strong to cause suffocation. 



For internal treatment give five or ten grains each 

 of sulphur and hyposulphite of soda, once a day; the 

 food must be wholesome and nutritious. The walls of 

 the hen house should be whitewashed; the roosts and 

 floors washed with a 5% solution of carbolic acid, or 

 with Chloro-naptholeum or some such preparation; 

 the runs should be frequently sprinkled with lime. 

 Convalescing fowls should not be returned to the 

 main flock too soon.
