A perusal of the above tables shows that the percentage weight 

 of the kidneys is decidedly higher in meat-fed animals than in ani- 

 mals on a meat-free diet. A general summary of the results of the 

 four series of observations is presented in Table V. Of fifty-two 

 animals fed on a meat diet, the total weight was 4666 grammes, the 

 total weight of the kidneys being 63,39 grammes or 1,40 7(,; whereas 

 of fifty-five rats on the meat-free diets, with a total Aveight of 6895 

 grammes, the total weight of kidneys was 71,67 or 1,03 ^/q.
