Symptoms. These are essentially those of capillary bronchitis 

 advancing into pneumonia and even pleurisy. It may begin with 

 a foreign body in a large bronchium, which will keep up a local 

 inflammation for weeks or even months without extending to the 

 bronchioles and lung tissue. When, however, these latter are 

 invaded the symptoms are liable to prove distressing as the 

 disease advances by rapid strides. The breathing is hurried, and 

 oppressed, sighing or panting, the patient sitting on his hind 

 quarters, or standing, with his fore legs apart, his elbows turned 

 out, the nostrils blocked by discharges, the mouth open, or if 

 closed there is inflating of the cheeks and pufiing of the lips, the 

 projecting eyes and drawn muscles of the face express great 

 anxiety, and the discharges are tenacious, filamentous, frothing 

 or even bloody, and malodorous. 



Percussion and auscultation reveal limited areas of flatness 

 more particularly near the lower and anterior parts of the lung, 

 surrounded by lines of crepitation, and in adjacent larger bron- 

 chia, mucous rales, which, like the heart and abdominal sounds 

 may be conveyed through the consolidated areas. The mucous 

 rales may be combined with loud sibilant riles, or again, in the 

 advanced stages, with amphoric sounds owing to the formation 

 of cavities. Again all the successive symptoms of pleurisy may 

 be present, notably, intercostal tenderness, friction sounds, later, 

 flatness on percussion up to a given water line, the creaking 

 sound of false membranes on the stretch, and metallic tinkling or 

 splashing implying hydro-pneumothorax. 



From the first there has been elevation of temperature and 

 other indications of fever, which become more marked as the 

 disease advances, and finally culminate in a profound prostration 

 and debility, the result of the absorption of the ptomaines, toxins 

 and waste matters generally. These elements, together with the 

 defect in aeration of the blood, and its being dammed back in the 

 over distended systemic veins, lead to congestions elsewhere and 

 particularly in the liver and bowels with serious disturbance of 

 the digestive process. Vomiting occurs when even the blandest 

 fluids are introduced into the stomach, indigestion, constipation 

 and diarrhoea follow each other, and jaundice is not infrequent. 

 In such a case the gastro-entero-hepatitis may be the cause of 

 death.
