592 PLEURO-PNEUMONIA. 



the contagious pleuro-pneumonia, though, during the animal's 

 lifetime, they had declared that it had not the symptoms of 

 the disease. I must refer the reader to what I say con- 

 cerning the symptoms of the epizootic pleuro-pneumonia, 

 and need only add here, that in any sporadic inflammation of 

 the pleura and lungs there is not the same spasmodic action 

 of the nose or severe tracheitis. The animal is seized more 

 promptly, and not so insidiously as in the epizootic affection. 

 A shivering fit, loss of appetite, suppression of milk, are fol- 

 lowed by acute symptoms, which usually terminate favourably 

 in a week or ten days. The sporadic pleuro-pneumonia is 

 not so fatal a disease as the contagious form. 



In sheep there has been much pleuro-pneumonia on hilly 

 lands and in damp districts during the last few years. This 

 disease has nothing in common with the epizootic lung dis- 

 order of cattle, and is characterized by the general symptoms 

 of pleurisy and pneumonia. 



The treatment of sporadic pleuro-pneumonia is the same 

 as for any other inflammatory affection of the lungs, though 

 sometimes requiring to be more energetic, in consequence of 

 its great severity. 



CONTAGIOUS PLEUKO-PNEUMONIA OF CATTLE. 



This disease is popularly known now in this country as 

 the lung disease of cattle. It is the lunyenseuche of the 

 Germans, and technically termed by them peri-pneumonia 

 exudativa contagiosa, &c., &c. The first reports in Britain, 

 about twenty years ago, were written under the name, " the 

 new disease of cattle/' though a century since it had visited 

 our island. 



When Youatt wrote his treatise on cattle, nothing was 

 known of pleuro-pneumonia in Britain. What has induced 

 it since?
