It acts directly upon the blood and lessens the discharge from the 

 nasal membrances. Ferritone is a new and almost specific remedy 

 for all nasal discharges now sold by all first class druggists. 



CATARRHAL BRONCHITIS 



Bronchitis means, or is understood to be an inflammation of the 

 large bronchi (air tubes). Bronchiolitis is used to express an 

 inflammation of the capillary bronchi. 



Bronchitis occurs either as a primary or secondary disease. 

 It is very common among all domesticated animals, particularly 

 during the spring and fall, when it may become enzootic among 

 horses and cattle. It may occur alone, but is usually associated 

 with tracheitis and laryngitis (catarrh of the air passages), or on 

 the other hand it may attend pneumonia (bronchopneumonia). 



Several different forms of catarrhal bronchitis are recognized. 

 When the exudate is fluid and abundant, moist bronchitis or blen- 

 orrhea of the bronchi is spoken of. If the exudate is rather limited 

 and not so fluid a dry bronchitis exists. A fetid bronchitis develops 

 from a bacterial decomposition of the exudate. From the stand- 

 point of course, catarrhal bronchitis may be either acute or chronic, 

 and from the causes a verminous and a mycotic bronchitis may 

 be distinguished. 



The causes are usually refrigeration (changeable weather), 

 inhalation of mechanical and chemical irritants (dust, smoke, chemical 

 fumes), aspiration of fluids, such as liquid medicines unskillfully ad- 

 ministered, blood, pus or solid matter, such as food which gains access 

 to the windpipe, especially when the pharynx is paralyzed. Certain 

 animal parasites and bacteria are also causes. 



Secondary bronchitis occurs with most of the infectious diseases 

 affecting the respiratory tract (influenza, strangles, tuberculosis, 

 hog-cholera). 



SYMPTOMS 



The characteristic symptoms of acute catarrhal bronchitis are 

 cough, which at first is short, dry and painful, but later with the 

 accumulation of liquid exudate becomes looser and less painful. 

 Nasal discharge is present and during the act of coughing bronchial
