12 BULLETIN 1012, U. S. DEPARTMENT OF AGRICULTURE. — 
was a very high rate in the acute stages of the sickness. That this 
symptom did not appear in the Z. paniculatus cases may be explained 
by the fact that most of the animals were not very sick; that is, the 
sickness could not be considered as acute at any time. It did occur, 
however, in Sheep 569, which was very sick. This. animal, too, 
as well as Sheep 644 nal 647, exhibited labored breathing. It may 
be remarked, in this connection, that under normal conditions there 
is frequently great variation in the respiration of sheep; under excite- 
ment the rate may be temporarily very high. 
Other. symptoms.—Some of the animals groaned and gnashed thoi 
teeth during the sickness, and Sheep 569 and Sheep 647 went into 
a condition of coma. Coma is also a frequent symptom in the - 
animals made very sick by Z. gramineus, as shown in Bulletin 125. 
In general, the symptoms were practically identical with those 
seen in Z. gramineus cases, but less pronounced, because of the 
smaller toxicity of Z. paniculatus as compared with Z. gramineus. 
DURATION OF SYMPTOMS. 
‘The following table shows the time that elapsed between the first 
and last observed symptoms. It should be noted that this probably 
does not indicate accurately the entire time during which the animals 
were sick, because in many cases the sickness persisted for a greater 
or less time after the last note was made.
