PLEUBO. PNEUMONIA. 



THIS is practically an incurable disease, and we can give no 

 remedy for it. It is a malignant fever, almost entirely con- 

 fined to cattle, and, on account of its contagious nature, 

 spreads with great rapidity. Heretofore it has been confined chiefly 

 to the regions east of the Alleghanies, but recently it has threatened 

 an invasion of the Central States bordering on the Mississippi River. 



So fatal and contagious is this 

 disease, and so uncertain are all 

 known remedies, that stamping it 

 out by killing the affected animal, 

 as soon as its symptoms are recog- 

 nized, is the usual method of deal- 

 ing with it. Burying the carcass 

 deeply, or burning it and disin- 

 fecting thoroughly, isolating sus- 

 pected or exposed animals, and 

 using disinfectants in all places where the animal virus may be 

 present, are the only measures that can be depended on to check 

 its course. ' 



The disease may be conveyed by close proximity to the excre- 

 tions of affected animals, as well as by actual contact. Like other 

 contagious diseases this has a period of incubation, in which the 

 poison lies dormant, without any special indication of its presence. 

 This period may extend, in very malignant cases, from 4 to 6 weeks, 

 when the virulence of the epidemic is subsiding, or in cases where 

 the epidemic is of a mild form. • 



The first stage of the disease is indicated by a rise of tempera- 

 ture, the thermometer indicating 103° to 106° F. There is an 

 increased frequency of the pulse, loss of appetite, a staring condition
