Blood Fat in Fowls 



with methods of selecting high producing and low producing hens, i 

 their only reference to the problem of blood fat in the fowl has \M 

 fully quoted by us. 3 Warner and Edmond published nothing on blootfj 

 in relation to sex nor in relation to laying and non-laying until 11 moa 

 after the paper by Lawrence and Riddle appeared, which dealt exclusre 

 with these problems and not with that of high and low production. Tl 

 samples for this purpose were not drawn until 2 months after this pubfr 

 tion. 



2. The data of Warner and Edmond when properly classified and & 

 lyzed confirm the conclusions of Lawrence and Riddle in so far as the pm 

 lem of sex and of laying and the non-laying condition of the bird is 

 cerned. 



3. The data of Warner and Edmond are not sufficiently extensiv 

 decide finally the question of the possible relationship between percem 

 of blood fat and high and low production. When properly classified 

 logically and adequately analyzed statistically they indicate the ine 

 rectness of the conclusion of Warner and Edrnond 17 that, &quot;There is littl 

 no correlation between the amount of fat in the hen s blood and her yea 

 egg yield.&quot;
