However, it is impossible for one who is not an expert to diagnose the 

 state with certainty. The apparent sj^mptoms are the same as when 

 the animal is aifected with pleuro pneumonia. 



BRONCHO-PNEUMONIA. 



This is also a common complication. Either one or the other may be 

 first in operation. When bronchitis affects the smaller bronchial tubes 

 the inflammation readily extends to the air-cells and thence to the lung 

 tissue, constituting pneumonia. Or the bronchial tube may be second- 

 arily involved by the extension of the inflammation from the air-cells. 

 Nothing in regard to the treatment of this condition requires to be said 

 here, as it has been fully described when speaking of bronchitis and 

 pneumonia as separate diseases. A brief review of some of the unfa- 

 vorable results of pleurisy and pneumonia will not be out of place here; 



SUPPURATION AND ABSCESS IN THE LUNG. 



There are instances, and especially when the surroundings of the pa- 

 tient have been bad, when the inflammation terminates in an abscess 

 in the lung. Sometimes, when the inflammation has been extreme, 

 suppuration in a large portion of the lung takes place. Impure air, the 

 result of improper ventilation, is the most frequent cause of this termi- 

 nation. The symptoms of suppuration in the lung are an exceedingly 

 offensive smell of the breath, and the discharge of the matter from the 

 nostrils. 



MORTIFICATION. 



Gangrene or mortification means a death of the part affected. Oc- 

 casionallj', owing to the intensity of the inflammation or bad treatment, 

 pneumonia and pleuro-pneumonia terminate in mortification, which is 

 soon followed by the death of the animal. 



ABSCESS IN THE SPACES BETWEEN THE RIBS. 



Abscess of the intercostal spaces has been recorded as a result of 

 pleurisy. Following the attack of i)leurisy an enlargement appears on 

 some part of the chest, which may burst of its own accord. When it 

 makes its appearance it is advisable to apply poultices of linseed meal 

 and hot water, or bathe it continuously for hours at a time with water 

 as hot as can be comfortably borne. This treatment will hasten the 

 formation of matter. When it is soft in the center it should be lanced 

 and the matter allowed to escape. The course of tonic treatment and 

 nutritive food advised in the treatment of pleurisy should be kept up. 



HEMOPTYSIS — BLEEDING FROM THE LUNGS. 



Bleeding from the lungs may occur during the course of congestion 

 of the lungs, bronchitis, j^neumonia, influenza, purpura hemorrhagica, 

 or glanders. An accident or exertion may cause a rupture of a vessel. 

 Plethora predisposes to it. Following the rupture of a Vessel the blood 

 may escape into the lung tissue and cause a serious attack of pneu- 

 monia^ or it maj fill up the bronchial tubes and prove fatal by sufifocat-
