These elements of uncertainty form, of course, one of the 
troublesome points in all experiments of this kind ; and it is 
only by taking a sufficient number of animals, and by repeating 
experiments, that such circumstances can be prevented from 
vitiating the results. In the present instance, whilst it will be 
noticed that the sheep named lost in weight, in some cases more 
and in others less, it would be hardly fair to leave them out of 
account altogether, inasmuch as it is probable that the other 
sheep in the pens profited at the same time by having more 
than their ordinary share. 
As the spring advanced, the sheep fed on linseed-cake were 
found to be decidedly the most healthy-looking of all, and 
their wool was brighter and more compact in character than 
that of the sheep of other pens ; the wool of those in Pens 2, 
4, and 5 appearing to be especially loose. After continuing 
the experiment for 95 days the swedes were consumed, and 
the sheep were weighed on March 28, the weights then being 
as follows : —
