the bladder, and the urine passes away involun- 
tarily. In some cases the bladder may be inflamed 
or greatly irritated, and the presence of even 
healthy urine could not be tolerated and would 
be passed off as soon as it reached the bladder. 
When it is caused from loss of power the animal 
will not be feverish or be suffering any pain, but 
should it be caused by inflammation or irritation 
there will be more or less fever and pain. 
Treatment: If from weakness and loss of power 
give two or three drops of fluid extract of nux 
vomica and from thirty to sixty drops of tincture 
chloride of iron at a dose in a little syrup three 
times a day. Ten to fifteen drops of turpentine 
at a dose in oil or syrup is often useful. Five drops 
tincture of cantharides at a dose in a little water 
three times a day has often good results. If it is 
caused by inflammation or irritation remove the 
cause, if possible, and give medicine required to re- 
duce the inflammation, such as one to two ounces 
-epsom salts and two to three drops of fluid extract 
of belladonna three or four times a day, or after 
the physic has operated give one to two grains of 
opium and three to four grains of calomel three 
times a day, and encourage the animal to drink 
flaxseed tea, effusion of slippery elm or barley 
water. Feed on an oatmeal and milk diet.
