Filter through a double filter. Then treat the moist residue on 
the filter paper with a few drops of tr. guiac., which gives a blue

Phosphates. —Phosphates are usually found in urine as an 
amorphous white substance which clears up on addition of acetic 
acid. Very often neutral or alkaline urine will become cloudy 
when boiled ; this may be due to albumin or phosphates. They 
may be distinguished by the acetic acid test, which dissolves 
phosphates but not albumin.

RUPTURE OF THE INTERNAL ILIAC ARTERY. 
By W. J. Martin, V. S., Kankakee, Ill.

I found the rectum hanging down, cold and of a dark-red color. 
The mare was lying full length on her side and at intervals

abdominal pain. 
I informed the owner that in my opinion the case was hope¬ 
less, and that the mare would not live through the ordeal of 
delivering the colt; but he insisted that I should go ahead and
