Experiment II . — A year-old heifer ate in twenty-four hours 
2 lb. 6 oz. of the half -dried leaves and twigs. No effect. 
In these two experiments the leaves were from the male plant. 
Experiment III . — Three calves, aged about seven months, con- 
sumed in two hours 3 lb. 6 oz. of half-dried leaves and small twigs 
from a female plant. No effect. Three days later (October 24) the 
same three calves ate 10 oz. in two hours. No effect was observable 
on the following day (the 25th), but on the morning of the 26th 
one of the calves was noticed to be ill, and within half an hour 
thereafter it died. The symptoms noted were great depression and 
hurried respiration. The post-mortem examination revealed most 
intense gastro-enteritis. The entire mucous membrane of the fourth 
stomach was of a deep crimson-lake colour, and the intestinal 
mucous membrane was acutely inflamed, the hyperaemia being most 
marked in the small intestine. The contents of both stomach and 
intestines were deeply tinged with blood. The spleen was swollen 
and soft — almost diffluent ; it bore a striking resemblance to an 
anthrax spleen, save that the colour of the pulp was brighter. The 
other organs showed no marked deviation from the normal. 
Experiment IV . — The two surviving calves from the preceding 
experiment consumed, on November 7, 3 lb. of half- dried leaves and 
small twigs from a female plant. On the 8th one of the calves 
appeared a little dull, but both continued to eat and ruminate. On 
November 12 the same two calves ate 4 lb. 7 oz. of half-dried leaves 
and twigs from a female plant. No signs of disturbance followed. 
Experiment V . — A donkey ate in twenty-four hours 54 oz. of 
half-dried leaves from a female plant. No effect. 
Experiment VI . — Two guinea-pigs consumed 14 oz. of half-dried 
leaves from a female plant in seven ty-two hours. No effect. 
This inquiry will be continued.
