Three cattle had died and three died later among a bunch of 
two and three year’old steers which had been fed for some time 
on a feed and pasture lot. It had been frozen hard for some 
time. Previous to the occurrence of the disease it thawed out a 
few inches deep and became dotted with deep and broad hoof 
prints, (made in the soil before, frost of course), that were filled 
with surface water, and from which the cattle drank. 
There was an old pretty-well-filled pond in the lot which had 
been covered with ice all winter, but from which Mr. Elliott 
Palmer, the proprietor, dipped water for his cattle some few days 
before any died from mad-itch. Some had had a gradual change 
of feed from hay to hay and corn ; one of those that died had had 
corn and hay all winter. No change even in quantity. I think 
all cattle though had a change in the quality of hay some time 
before the malady made its appearance. 
After the first deaths the cattle were removed to an adjoining 
field through which surface water of this pond circulated by 
means of a deep stream. This field also was dotted with holes 
filled with ground surface water. Two cattle took sick in this lot 
and died. Then all the rest of the cattle were removed to still 
another place, dryer and higher than either of the two fonrter. 
No disease after that. 
Symptoms. 
The first symptom that was noticed in several cases was a 
slight watery discharge from the eyes, and a rapidly increasing 
dumpishness. I am not positive that these symptoms are invari¬ 
ably present at the beginning. There is always some intense 
itchness (in all appearance) at some part of the head, which is 
rubbed and scratched severely on stumps, trees, fences, etc. 
Usually one side of the head or only the lower maxillary presents 
this feature. Rubbing is frequently so constant and hard that it 
causes considerable irritation of the surface of the skin. Some¬ 
times it even becomes raw and bloody, and the subcutaneous tis¬ 
sues become infiltrated with serum, and a prominent swelling oc¬ 
curs. Symptoms of nervous excitement make their appearance at 
an early date. They coincide with this rubbing. They are char¬ 
acterized at first by a wild glaring look, which soon acquires in¬ 
tensity and seems to be a mingling of fright and threats to scare
