 POUEEITUEE AIGUE. 



THIS enzootic disease prevails to a considerable extent in 

 Ireland. It appears also to be a disease of modern date, and 

 the first and best account of it in this country, was published 

 by Mr T. W. Gowing, a highly intelligent veterinarian, re- 

 siding in Camden Town, London. Mr Gowing's observa- 

 tions were on a farm in Middlesex, and the disease appeared 

 on rich ground, where the grass was good, and no noxious 

 plants existed on it. During the same year 1849 and 

 since, many outbreaks have been alluded to, and the mortality 

 induced by the disease is occasionally very great.
