emu-ays. 
It will be noted that the two cattle were sick for the same period. 
They received the plant mixed with hay, and of the two affected 
No. 900 ate the material in about 4 hours. No. 905 was found sick 
in the morning, and the time consumed in eating is not known. 
Of the sheep, the shortest period was a single observation, sheep 603 ; 
and the longest, in the case of sheep 642, was 90 hours and 5 minutes. 
The average of the sheep cases, excluding Nos. 637 (August 10), 
645, 603, and 620, in regard to which the records were incomplete, 
was 29 hours and 16 minutes. 
To one of the sheep (No. 645) Zygadenus was fed in hay, the 
feeding being continued for 8 days, and during this period the sheep 
was sick four times. All the other sheep were fed by the balling gun. 
Of the 3 pigs, one was sick during the night when not under con- 
stant observation. In the other two cases, the duration of illness 
was approximately the same with an average of 3 hours and 52 
minutes. 
To the pigs chopped bulbs were given, mixed with bran. Pig 23, 
September 24, ate only a couple of mouthfuls. Pig 22 ate 0.117 
pound of the plant in 2 minutes. Pig 23, September 26, ate 0.067 
pound of the plant in 1 minute. In each case the pig vomited, 
emptying the stomach quite thoroughly, and had no further symp- 
toms. 
COMPARISON OF DURATION OF SYMPTOMS FROM DIFFERENT SPECIES OF ZYGADENUS. 
In Table 3 are included the maximum, minimum, and average 
duration of illness in experimental sheep which were either force-fed 
or drenched. In this table the deaths are included as well as re- 
coveries, inasmuch as a comparison of figures did not seem to indicate 
that the duration of illness was shortened by a fatal issue.
