It is seen from the averages of this table that a sheep will be poisoned 

 by eating 2.228 pounds daily for 21.58 days, getting in this time a 

 total of 46.34 pounds. These figures must not be construed, however, 

 as giving very exact limits, for the time necessary to produce intoxi- 

 cation varies from 12 to 47 days, and the daily dosage from 1.438 to 

 3.143 pounds. Moreover, there is no clear relation between the 

 quantity fed and the time necessary to produce results. In some 

 cases it was necessary to continue the smaller dosage a longer time, 

 as in Sheep 448 and Sheep 423; but Sheep 420 had nearly the smallest 

 daily feeding and became sick in 18 days. Neither in the three cases 

 which ended fatally is it clear that it was because of greater feedings 

 or longer period of experimentation.
