Table 2 is far from giving the exact time which elapsed between 
the feeding and the development of symptoms. In some cases the 
feeding continued over a considerable period, so that there may 
have been some poisonous effects even before the conclusion of the 
feeding. The time is computed from the end of the feeding. There 
is some indefiniteness in the time at which symptoms developed. 
The animals were not. in all cases, under constant observation, and 
in some the first symptoms were noted when the animals were ob- 
served in the morning, and it is possible that they had been sick for 
a considerable period before that time. 
The shortest time noted was in the case of cattle 945 — 8 hours and 
35 minutes. The longest period was in the case of pig 20 — 43 hours 
and 10 minutes. In most cases, however, the time was a little less 
than 24 hours. 
In general, a period of several hours elapses before symptoms ap- 
pear, and this time, in some cases, may be between one and two days. 
It should be noted that the chickens quoted in Table 2 received 
seeds, while the other animals, with the exception of pig 10. August 
16, received plants in the young cotyledon stage. This difference in 
material apparently did not affect the time elapsing between the 
feeding and the development of symptoms. 
DURATION OF SICKNESS 
Table 3 shows the duration of illness in cases of animals that either 
were sick or died.
