The experimental work had three objects in view: 
(1) To determine whether the plant was poisonous in summer and early fall. 
(2) To settle definitely the question of the danger to live stock from eating hay 
containing Cicuta. 
(3) To obtain material for verifying and amplifying the description of symptoms 
and the effects of Cicuta poisoning. 
This work was carried on in the summers of 1910 and 1911. 
FEEDING CICUTA TO SHEEP IN i910. 
In Table I is given a summarized account of the sheep-feeding 
experiments of 1910. The details of the cases follow. An attempt 
was made to feed two other sheep, but neither could be induced to 
eat the material.

Case No. 108. 
Case No. 108, a wether weighing 100 pounds, was taken out of the pasture on the night 
of August 12 for feeding with Cicuta. The feeding was commenced at 11.30 a. m. 
on August 14, when he was given ground tubers of Cicuta occidentalis. During the 
day he ate very little except what he got accidentally in picking out oats that had been 
thrown upon the ground material. On the morning of August 15 he was given an 
additional quantity of Cicuta roots, this being mixed with hay with the feed that had 
remained from the preceding day. Apparently very little of this was eaten except 
what was obtained accidentally in connection with taking the hay, but by the night 
of August 16 he had eaten a considerable amount of roots. On August 17 he was 
fed stems and tops of Cicuta; the plant being in seed. This was entirely eaten up 
with what remained of the Cicuta roots by the night of August 17. On the morning 
of August 18 more of the ground roots was fed with cut hay and it was all eaten. 
Because of lack of material he was not fed on August 19. On August 20 and 21 he
