companied 'by 'a grunt or moan. A discharge sometimes issues 

 from the eyes and nose, the horns and ears are cold, and no sound 

 is heard on auscultation. A slight tympanitic condition may 

 occur, with an offensive diarrhoea, grating of the teeth, and gan- 

 grene of the lungs, followed by death. Young animals are more 

 subject to the disease than old ones. 



PosT-MoKTEM Appearances. — There is a dullness of the 

 pleura, the substance of the lungs is red and congested, giving 

 them a marbled appearance. There is a consolidation of the 

 lung, which will sink when placed in water. The pleura is also 

 involved, and an effusion into the ])leural cavity has taken place. 

 The ribs present a bare appearance, being stripped of their 

 pleural covering, and have an unnaturally white appearance. 

 The disease is susceptible of transmission from sick to healthy 

 animals by cohabitation, or even without immediate contact, as 

 it may be taken at a distance. Stables occupied by diseased ani- 

 mals are not safe for healthy cattle for several months. The 

 disease has been produced in healthy animals by allowing them 

 to run upon pastures three months after diseased cattle have 

 occupied them. Hay soiled by infected animals has also produced 

 the disease three months afterwards. Twenty per cent of ani- 

 mals resist the contagion. Eighty per cent manifest various 

 effects of its influence. Fifty per cent are seized with decided 

 symptoms of pleuro-pneumonia, and of these fifteen per cent 

 succumb. 



Treatment. — Treatment is not advisable. Slaughter and 

 burial is the most effectual remedy. 



Disinfection. — All sheds, cow-houses, or other premises 

 which have contained cattle affected with the disease, should be 

 thoroughly cleansed and disinfected. The best and cheapesit way 

 is to burn sulphur in the buildings; to whitewash the stalls, roof, 

 and every portion of the building with lime wash containing 

 carbolic acid, in proportion of one pint of crude acid to each 

 bucketful of whitewash.
