REPORTS OF CASES. 
be weak and easily fatigued. Day before, September 3d, she 
was noticed to pass black-colored urine. Appetite good up 
to noon of the 4th, with slight colicky pains. 
On examination I found temperature io6f°, pulse 85, weak, 
breathing accelerated, membrane reddened, left lung congested 
and urine very black; ears and legs partially cold. I reserved 
my diagnosis, and prescribed slippery elm gruels. Also bel- 
lad. fl. ex., tinct. aconite and tinct. iron, to be given in gruel 
with sod. hyposulp. in drinking water. Prognosis grave, but 
the owner laughed at this, as he did not consider much wrong. 
I called on the morning of the 5th and found my patient 
on the field ready for the grave. I held a post mortem and 
found all healthy except the lung (left), with the peritoneum 
darkened, and kidneys slightly congested. When through 
with the post mortem one of the farm hands told me to look 
at a big bay gelding (one that had helped haul out the mare),

and he said he ate well. 
That night, the 5th, I was again called to the farm and 
found the gelding in bad condition; with severe pains, urine, 
if anything, darker than mare’s, circulation 70, temperature 
104°. I then suspected something they were eating. I put 
him under same treatment as the mare, increasing the sod. 
hyposulp. I drew some of the urine and analyzed it, and found 
blood corpuscles in abundance, with some kind of spores. I 
do not know the name. 
In the morning I found the patient worse in every way ; 
no appetite, neither would he partake of water, temperature 
I0 5i°> pulse 90, breathing 40, severe abdominal pain, and fre¬ 
quent urination, membrane pale and of a dark hue. Six or 
eight weeks previous I had a bad case of purpura on the same 
farm, and 1 thought it might be a hidden case, but could see no 
symptoms whatever. I telegraphed for my father at Wooster, 
O., and consulted with him, and he agreed with me as to the 
diet or drinking water causing it. We continued the same 
treatment, with addition of spts. turpentine. 
Next day I examined all the horses on the farm, some ten or 
twelve head, and found two affected with dark urine, other-
