4. As it was thought possible that lactic acid might be one of the 

 substances into which sugar split up in the organism, quantita- 

 tive estimations were made of it in the blood and certain of the 

 tissues. 



(a.) Quantity of lactic acid in the blood at various times after the 

 intravenous injection of sugar. 



It is here seen that a marked increase of the lactic acid takes place 

 after the injection of sugar. Further, that after the fourth hour it 

 decreases slower than does the percentage of sugar itself in the 

 blood. In the following table the effects of this slower decrease is 

 well shown. 



These results give an average of 0'065 per cent, of sugar as against 

 0'096 per cent, of lactic acid in the blood. Whereas, in dogs on 

 no'rmal diet, Gaglio has shown the quantity of sugar in the blood was 

 more than the quantity of lactic acid. 



(6.) Quantity of lactic acid in the liver and muscles as compared 

 with the amount in the blood after ligature of the ureters and the 

 injection of 10 grammes of sugar per kilo, of dog's weight.
