carcass- weljilit to live-weight, and particularly in the percentage 
of loose or inside fat. 
In the summary at the bottom of the Table wc have again 
shown, that which has already been otherwise indicated, the 
much greater irregularity in the rate of increase among the 
Leicesters than among either of the cross-bred lots. Thus, 
among the Leicesters the average gain of the 4 of smallest 
increase is less than half that of the 4 of greatest increase ; the 
numbers being, for the former 28 lbs. per head, and for the latter 
61f lbs. The variation among the cross-breds is much less. 
Among the wethers the average gain of the 4 of smallest increase 
was 35j lbs., and that of the 4 of largest increase bh^ lbs. ; and 
among the ewes, that of the 4 of smallest increase was 32f lbs., 
and of the 4 of largest increase 52f lbs. The bottom lines of 
these columns of increase show, however, that although the dif- 
ferences were much greater within one lot than another, yet the 
averafje increase per head of each lot of 40 sheep was very nearly 
identical for the Leicesters, cross-bred wethers, and cross-bred 
ewes. It was, however, for the ewes about 2 lbs. less than for 
either of the other lots. 
With, as already noticed, great diversity in the amount of 
wool yielded by sheep of nearly equal increase, we have still, 
with all three lots, somewhat more wool with the sheep of lai'gest 
increase than with those of either smallest or medium rate of 
increase. The summary shows too, as we should expect, that in 
each of the allotments, according to increase, the Leicesters give 
more wool than the cross-breds ; and, among the cross-breds, 
the ewes give upon the whole more wool than the wethers. 
The actual carcass or dead weight (calculated in stones of 
8 lbs.) varies among the 16 Leicesters killed from little more 
than 6t stones to nearly 12^ stones ; among the 16 cross-ljrcd 
wethers it ranges only from nearly 8 stones to nearly lOi stones ; 
and among the slaughtered cross-bred ewes the variation is from 
nearly 7f stones to 9f stones. With this great variation in the 
amount of meat produced per head, and particularly among the 
Leicesters, the average of the whole 16 of each lot killed agrees 
more nearly than we should have expected. Thus the average 
yield of mutton of the 16 Leicesters killed is about 9^ stones; 
that of the cross-bred wethers stones ; and of the cross-bred 
ewes nearly 8J stones. The cross-breds have therefore given, 
on the average, nearly as much meat per head as the Leicesters, 
As already intimated, however, all three lots would have been 
somewhat better for another month of feeding ; which, we may 
calculate, would have given at that stage of the fattening pro- 
cess an average of nearly a stone per head more carcass-weight 
for each of the three lots of sheep.
