Chronic Pharyngitis. 73 



of chloride of lime, or one drachm of mercuric chloride will 

 usually prove effective. The poultry runs should be liberally 

 sprinkled with a solution of sulphuric or hydrochloric acid, one 

 part to 1000. The same may be used on the building, which 

 may further be fumigated by burning sulphur. 



Poultry shows should be kept under the most rigorous sanitary 

 supervision. 



Curative treatment is only profitable in the case of specially 

 valuable birds, and even then only, as a rule, when the disease is 

 ■confined to the nose, mouth, larynx and pharynx. The affected 

 parts ma j' be brushed with a solution of chloride of iron (1 dr. 

 ■of the tincture to 1 oz. water), nitrate of silver (2 grs. to 1 oz. 

 water), sulphide of calcium (}4 dr. to 1 oz. water), tannin (10 

 grs. to 1 oz.). Tincture of iodine may be applied direct, or a 

 solution of carbolic acid or of creosote or creolin (1 part to 50) 

 will often succeed. Thomassen recommends the removal of the 

 false membranes and the application of boric acid followed by dry 

 sulphur. Benoist says the majority recover when made to inhale 

 the fumes of oil of turpentine evaporated at a gentle heat twice 

 a day. 



As internal medication, or to correct the intestinal affection, 

 sulphate of iron may be dissolved in the drinking water or 

 salicylic acid may be given in pill form with molasses.

 electuaries. Bitters. Iron. 



Causes and Nature. Chronic pharyngitis in animals may be a 

 simple continuation of the acute, in a milder form, or it may 

 assume a subacute or chronic type from the first and never rise 

 to the intensity that would characterize the acute. It may be 

 a simple catarrhal affection or it may become more or less follicu-
