Purulent Pleurisy {Empyema) in Swine. 343 



Symptoms. There are the symptoms of pleurisy, complicated 

 by those of the wound or injury ; the indications of a foreign 

 body advancing through the chest toward the heart, especially 

 tympanies of the rumen, foetid regurgitations, a line of flatness 

 on percussion from the reticulum forward with a mucous or 

 bubbling r^le, an irregular action of the heart, and pasty 

 swelling around the sternum ; and, finally, the crucial test of 

 drawing off a little liquid with a hollow needle and subjecting it 

 to examination. In cases due to uterine suppuration the vaginal 

 discharge will guide ; in pyaemia the discovery of multiple ab- 

 scesses ; in tuberculosis the disorder of the digestion, the pres- 

 ence of tubercles in the throat, the percussion and auscultation 

 indications of tubercles in the lungs, the swelling of the lymph 

 glands in the abdomen, or in the intermuscular groups, — pre- 

 pectoral, prescapular, prefemoral, inguinal, etc., — and, finally, 

 the result of the tuberculin test. 



Treatment. Beside the general treatment of the primary cause, 

 the removal of the infected effusion with the same antiseptic pre- 

 cautions as recommended in the horse will be required. Also the 

 same general dietetic and hygienic measures. The case is not 

 hopeful in any instance, and is especially bad in tuberculosis. 

 The most hopeful cases are such as supervene on simple penetra- 

 ting wounds, where the infection has not yet seriously advanced, 

 and the strength of the patient is well maintained. But these 

 are just the cases in which a certain salvage can be secured by 

 turning the animal over to the butcher. 



PURULENT PLEURISY (EMPYEMA) IN SHEEP. 



In sheep the usual cause is inhalation broncho-pneumonia, 

 hsemorrhagic septicaemia affecting the chest; and traumas. The 

 symptoms are the counterparts of those of the ox and the gen- 

 eral treatment the same. 



PURULENT PLEURISY (EMPYEMA) IN SWINE. 



The strong indisposition of the pig to pus infection serves to 

 protect it against empyema, and a further measure of protection 

 is found in the usually thick panniculus adiposus. Still in ex- 

 ceptional cases .purulent and septic infection in the lungs will in-
