two in Lot IV. Their average ages were eight and a-quarter 

 weeks, in Lot I., nine and a-half weeks in Lot II., eight and 

 three-quarter weeks in Lot III., and nine and a-half weeks in 

 Lot IV. The preliminary feeding of these calves, and the 

 rations fed up to August 7th, were identical with those in the 

 experiment described above. After August 7th, that is, during 

 the weaning period, the rations were as follows : —

From the time weaning was completed on September 4th, 

 and up to October 30th, the calves received linseed cake and 

 Indian meal in the following quantities per head per day : —

From October 30th onwards the calves in this experiment 

 were treated and fed exactly as were those in the first experi- 

 ment. 



The cattle reared on separated milk and cod liver oil yielded 

 the largest increase in live weight, and those reared on whole 

 milk gave higher returns than the two remaining lots.
