As stated before, no attempt is now made to explain these differing 

 requirements, but the question of a possible correlation between the 

 rate of gain and economy of gain naturally suggests itself. In fact, a 

 casual inspection of the groups leads one to expect such a correlation. 



In Tables IX to XV the individuals are ranked in order of efficiency 

 both as to daily rate of gain and economy of gain. 



Table IX. — Rank of pigs of test A in rate and economy of gain 



Table X. — Rank of pigs of test B, grotip i, in rate and economy of gain 



Table XI. — Rank of pigs of test B, group 2, in rate and economy of gain 



Table XII. — Rank of pigs of test B, group j, in rate and economy of gain
