EXTRACTS FROM EXCHANGES. 
Found the cow down, delirious, urine retained, fseces ex¬ 
tremely hard, cow very fat. Cow did not respond to treatment 
and died. I have not told yon that upon drawing her urine, it 
effervesced like soda water or lager beer. As the self commis¬ 
sioned superintendents expressed it, her water had a great 
head on it. 
Post-mortem showed pneumonia, calf (heifer) full grown and 
properly presented ; bladder empty, rectum inflamed. ^ I should 
have said that faeces were hard as rocks and coated with bloody 
inncons, not blood. Physic and enemas failed to act. Had to 
use stomach pump to give physic, as too weak to swallow. 
All that bothers me is, why did that urine effervesce Has 
any one else ever seen the same ? Can any reader account 
for it? _

few hours after. The lesions'at the post mortem were unusual
