of which it diminished, the appetite became impaired, and 

 the animal was observed by the dairyman suddenly to fall 

 down. She was raised, and the body and extremities rubbed, 

 and she apparently recovered, remaining seemingly in health 

 for the period of five or six weeks, when she again as suddenly 

 fell Being raised, and the same means adopted as at first, 

 she soon after again recovered ; but she now lost flesh rapidly,

" Examining the points of attachment, the nature of the 

 abnormal deposit was disclosed, and also the causes that 

 must have been in operation to produce it. The serous lining 

 membrane had evidently been intensely inflamed, and deposi-
