Septicemia Hemorrhagica of Bovine Afiimals. 59 



ones are omitted or deferred. So long as the lesions are confined 

 to the chest, they are betrayed b}' hurried and even oppressed 

 breathing or dyspnoea, a frequent, moist, suffocative cough, per- 

 sistent standing to favor respiration, and there are the percussion 

 and auscultation indications of consolidated lungs or hydrothorax. 

 The mucosae are usually of a darker red, than in the external 

 form, cyanotic indeed, and the peculiar asphyxial position, with 

 legs apart, head extended, dilated nostrils and open mouth may 

 be very significant. These symptoms are likely to be modified 

 or supplemented before death, by those caused by intestinal or 

 renal disorder. In the thoracic form in young animals death by 

 suffocation may occur in a few hours, but more commonly the 

 disease progresses slowly and a fatal result is not reached until 

 the fourth day or even the eighth. This form is common in the 

 deer, and less so in cattle. 



In the intestinal or abdominal form the usual sudden onset and 

 high fever, are complicated by inappetence, tympany, rumbling 

 of the bowels, uneasy movements of the hind feet, perhaps twist- 

 ing of the tail, looking at the flanks, and even lying down and 

 rising. There is frequent, violent straining with the passage of 

 fasces at first glazed, later streaked with blood, or mixed with 

 pseudo-membranous casts, and very soon soft, watery, frothy and 

 foetid. These are usually black or reddish black from contained 

 blood. 



The urine may also be blood-stained. 



Before death, complications on the lungs or skin will often come 

 in to assist in diagnosis. 



In the chronic and subacute types the lesions are often concen- 

 trated on the lungs, and there are a moderate fever cough, 

 hurried breathing under exertion, dulness on percussion over 

 limited pulmonary areas, blowing sounds, mucous rales, crepita- 

 tions and more or less muco-purulent expectoration. These 

 phenomena are all the more significant if complicated by digestive 

 disorders, costiveness, fcetid mucous diarrhoea, tympany, or by 

 the eruption of the superficial swellings. 



Lesions. The swellings on or tinder the skin or among the 

 muscles show extensive straw-colored exudations, colored at points 

 with blood, with enlargement, infiltration and staining of the 

 adjacent lymph glands. On the chest walls the sero-sanguineous
