 times a violent coughing and expectoration of large lumps

The best and ni,ost nutritious food, as well as the above- 

 named remedies, must accompany the fumigation. 



iJemar^.^— Calves and hogs not unfrequently suffer from 

 these worms, and I have myself observed numerous cases 

 where very valuable hogs were destroyed by the disease. 

 Their cough mostly commenced while quite young, but

ERYSIPELAS. 



Erysipelas, or wild fire, appears sometimes in spring among 

 young, and rarely among old sheep. The patients lose their
