98 DISEASES OF CATTLE. 



chest will give a tympanic, drum-like sound. The normal resonant 

 sound is exaggerated. 



TreatTnent. — 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. 



PULMONARY CONGESTIOX. 



Cattle that are overdriven or overworked are liable to pulmonary 

 congestion in an acnate 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 stimnlants internally, unload the 

 venous side of the heart by bleeding, and apply stimulating applica- 

 tions 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 break- 

 ing 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 of its own accord. Internally hemostatics are indicated, 

 and locally over the sides cold applications have a tendency to check 

 the hemorrhage. Give the animal a drench composed of 1^ drams of 

 gallic acid dissolved in a pint of water. 



ABSCESS OF THE LUNG. 



Abscesses of the lung sometimes form during the course of or sub- 

 sequent to tuberculosis or other diseases. An animal affected with 

 abscess of the lung usually has a protracted, feeble cough and a gen- 

 eral appearance of emaciation and anemia. The pulse is feeble and 

 the breath foul. An offensive discharge from the lungs frequently 

 occurs. Percussion and auscultation will aid in making a diagnosis 

 in this condition. 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. 



HYDROTHORAX. 



Hydrothorax, 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- 

 dition can be easily diagnosed by physical signs. A loss of the res- 

 piratory murmur will be noticed on auscultation, and on percussion 

 dullness or flatness on a line as high as the effusion has taken place.
