Two head of cattle, Nos. 641 and 648, were fed. No. 641 during the 
three days from July 26 to 28 received, per 1,000 pounds of weight, 
170 pounds of leaves, stems, and flowers of Cicuta. This was fed with 
a little hay im order to induce the animal to eat it more readily. No. 
648 during the four days from July 30 to August 2 received 266 
pounds of leaves, stems, flowers, and some seed of Cicuta. Neither of 
these animals suffered any ill effects from the feeding.
