THE DISEASES OF CATTLE. 301 



" Sept. 14. — All the symptoms of yesterday are aggravated 

 intensively. The eyes have stiU a heavy appearance, when

 gets up again and roars. Upon a person present putting his

" The larynx showed traces of intense inflammation, as also 

 did the membrane lining of the trachea, throughout its entire 

 length, and was most beautifully spotted, as was also the lungs,

 first and third stomachs parted upon the slightest touch, in 

 patches. The abdominal viscera, also, was similiarly spotted,

 of removing the diseased animals from the healthy ones. 



Treatment of Mange. — Let the animal have a table-spoonful 

 of sulphur in the food, for three or four days in succession ; in
