NONG'ONTAGIOUS DISEASES OF THE ORGANS OF RESPIRATION. 109 



tite is not decreased and the milk secretion is kept up. It may be 

 caused by an attack of asthma, or may result from chronic bronchitis. 

 The disease can be diagnosed by the marked interference with respira- 

 tion. The animal, as a rule, is emaciated, has a staring coat, and is 

 hidebound. If percussion is resorted to, the animal's chest will give 

 a tympanic, drum-like sound. The normal resonant sound is exagger- 

 ated. 



Treatment. The disease is incurable, and only a palliative form of 

 treatment can be carried out. The destruction of the animal is often 

 advisable, from a humane as well as from a financial point of view. 



IMLMONARY CONGESTION. 



Cattle that are overdriven or overworked are liable to pulmonary 

 congestion in an acute form, and sometimes pulmonary apoplexy. In 

 such cases the animal should be allowed to rest, and if the weather be 

 hot put in a shady place. Give stimulants internally, and apply stim- 

 ulating applications to the legs, and bandage. 



HEMOPTYSIS. 



This is a term used to signify bleeding from the lungs. The trouble 

 may result from a previous congestion of the lungs, or from a breaking 

 down of the lung substance, or from specific disorders. 



Bleeding from the lungs comes from both nostrils and from the mouth. 

 The blood is bright red, frothy, and accompanied by a cough, the flow 

 being somewhat profuse and intermingled with mucus. It may cease 

 <>f its own accord. Internally haemostatics are indicated, and locally over 

 the sides cold applications have a tendency to check the hemorrhage.

 in a pint of water. 



ABSCESS OF THE LUNG. 



An abscess of the lung sometimes forms during the course of or sub- 

 sequent to certain pulmonary diseases. An animal affected with abscess 

 of the lung usually has a protracted, feeble cough, and a general appcar- 

 i'.iisc of emaciation and antenna. The pulse is feeble and the breath 

 foul. An offensive discharge from the lungs frequently occurs. Per- 

 ion and auscultation will aid in making a diagnosis in this condi- 

 tion. The appetite is poor. Such animals go from bad to worse, and 

 their prompt destruction would, as a rule, be to the interest of the 

 owner. 



HYDUOTHORAX. 



IlydiDthorax, or dropsy of the chest, is not a disease in itself, but is 

 simply a condition where an effusion takes place in the chest cavity, 

 and is the result or effect of some disease', mostly pleurisy. This con-
