Among the cows that were fed pahn nut meal it is seen that all in 

 lot No. 1 show in general a higher per cent of fat while the meal 

 was fed than before, but this higher average is kept up for six weeks 

 after the meal was discontinued. Mabel 2d of lot No. 2 is the only 

 cow tliat shows a lower average both before and after feeding the 

 palm nut meal tlian during that period, but her total yield of fat 

 was less on the palm nut ration than on the usual ration. Ruby and 

 Sadie each had a higher average before the meal was fed and nearly 

 as high after as during the period of feeding the meal. Ruby's high 

 ■average at the beginning is probably due to her being fresh in milk.
