REPORTS OF CASES. 
four days it could not be obtained ; the eserine had been de¬ 
composed. We are unable to explain why, in the second 
test, the union of the barium oxide solution, and solution of 
eserine, was not marked by the production of the color; 
perhaps in the case before us the dilution was too great. 
In any event the subsequent reaction, namely, the blue 
coloring after drying, and the red coloring after moistening, 
can be accepted as conclusive proof of the presence of 
eserine. 
REPORT'S OF CASES. 
IS THIS ANTHRAX? 
By Dr. D. P. Frame, Y.S., Colorado Springs, Colo. 
During the last three weeks a very peculiar disease has 
broken out in two or three herds of horses in this vicinity. 
It has proved fatal in every instance, many of the animals 
being found dead in the pasture. 
Those animals which I have seen alive, present about the 
following symptoms: 
Pulse, 75 to ioo, very irregular, now full and strong, 
again almost inperceptible, and finally becoming very weak 
and fluttering; temperature, 102.5 to 103. 0 F.; respiration, 
labored; visible membrane of an intense dirty yellow, con¬ 
junctiva covered with dark petechial spots, breath very of¬ 
fensive. 
Sometimes a slight watery discharge from the nose, gen¬ 
era] condition good, but not high; great constitutional 
depression and languor, with a general desire to remain quiet. 
No colicky pain is manifest* 
There are no external swellings of any of the glands of 
the head, throat, or body, or of the tongue, and no crepitation 
of the skin has been observed during life. In all cases a pe¬ 
culiar sore breaks out on one or more of the feet, an exudate 
comes through the skin, usually on the coronet at the side of 
the foot, rarely in the heel, the skin dries and cracks, and 
blood oozes through. When washed the skin has an angry 
red look.
