the other cases where their controls did not receive any oil at 

 all. This shows that the olive oil alone, in the amounts here 

 given, does not produce any noticeable effects on the organ 

 weights. The percentages of water in the various organs are 

 given in table 5. 



From table 5 we see a considerable difference in the water 

 content between the control and test rats. The organs which 

 give a diminished percentage of water are the liver, spleen, 

 kidneys, and brain, while those which give an increased percentage 

 are the blood, pancreas, and lungs. The greatest difference 

 between controls and test rats is shown in the blood, pancreas, 

 and liver. Although the brain gave a very small difference in 

 the water content, nevertheless this difference is highly constant. 

 With a view to illustrating the constancy of difference in the 

 percentage of water in the brain, I have compiled table 6.
