The more extended feeding of the summer was done in the case of 
sheep. Table IV shows a summary of these experiments. In addi- 
tion to the thirteen animals listed in the summary, two (Nos. 145 
and 152) were brought in for feeding, but ate so little that they are not 
included in the sum total of the summer’s work. Five of the sheep 
(Nos. 136, 137, 149, 151, and 158) were fed upon the leaves and stems 
of Cicuta and received, per 100 pounds of weight, from 11.4 pounds, 
in the case of No. 137, to 143.3 pounds, in the case of No. 158. These 
amounts were fed in periods varying from one week to about ten days. 
None of the animals suffered any ill effects from the feeding, although 
in the case of No. 158 it ate of the plant nearly 50 per cent more than 
its weight. In all of these cases the sheep were fed exclusively upon 
the leaves and stems, with the exception of one or two cases, like 
No. 136, where a little hay was mixed with the material in order to in- 
duce the animal to eat it more readily. Nos. 157 and 143 were given 
leaves, stems, and flowers, mixed with enough hay to induce them to 
eat it more readily. No. 143 in eleven days ate 16.5 pounds per 100 
pounds of weight, while No. 157 in ten days ate 109.1 pounds, or 
just about the equivalent of its weight. Neither of these animals 
suffered any ill effects.
