72 SEPTICAEMIA HEMORRHAGICA 



and in some instances actual lameness. Some of the animals 

 dropped to the ground and died in a short time, apparently 

 without pain. Others were down when first observed to be 

 sick and lived for several hours in great pain as indicated bj' 

 groans, and spasms of the muscles. The paroxysms of pain 

 were apparently intermittent. There was extremely rapid loss 

 of flesh in the animals that were sick more than one da}'. 



Opportunities for the accurate determination of tempera- 

 ture at the beiginning of the disease were very few. It appears 

 that an initial temperature of 105. 6° F. was present followed 

 by a rapid decline. Painful oedematous swellings about the 

 legs, shoulders and under the throat were noted as early symp- 

 toms. The intestinal discharges were often streaked with 

 blood. In other cases the feces were black, tarr}^ or of a blood}', 

 serous nature.. Bloody urine and a bloody serous discharge 

 from the nose were present in some of the cases. The vaginal 

 and rectal mucous membranes were intenseh' congested. 



The marked swellings of the face, stomatitis, glossitis, and 

 convulsive movements of the jaws in the pneumonic form of 

 the disease described by European writers, more especialh' 

 Bollinger, were not observed by Wilson and Brimhall in any 

 of the recent cases. 



S 60. Morbid anatomy. The characteristic lesions of 

 the disease are widel}' distributed areas of hemorrhage, vary- 

 ing in size from a pin point to several centimeters in diameter. 

 They vary in color from light red to almost black. They are 

 frequently accompanied with a sero-fibrinous exudate, usually 

 yellow, but occasionallj' dark red in color. The hemorrhagic 

 areas in the animals just dead are not so dark as those in 

 animals that have been dead for some hours. The large areas, 

 some centimeters in diameter, are apparently due, in some 

 instances, to single hemorrhages infiltrating an extensive mass 

 of tissue, and in others to a number of minute hemorrhages 

 closely placed and partially coalescing. Gas is not present in 

 the subcutaneous connective tissue except cases where exten- 

 sive post-mortem changes have occurred. 



There is excessive fullness of the vessels of the subcu- 

 taneous connective tissue in the acute cases, especially in
