A third observer, Buchner 1 , continuing the observations of 

 Tschiriew, found that in asphyxia, as the quantity of carbonic acid 

 in the blood increased, that in the lymph diminished. 



Tension of From these researches, which do not, it is true, teach 



theco 2 of us the comparative tension of the gases of the lymph 



Lymph. anc [ blood, it was reasonable to come to the conclusion 



that probably the tension of the CO 2 of the lymph was smaller 

 than that of the blood. Direct experiments made by Pfluger 2 and 

 Strassburg 3 indeed shewed that the carbonic acid of the lymph has 

 a tension, slightly but decidedly, less than that of the blood. Ac- 

 cording to the views which formerly at least were held by many very 

 eminent physiologists, this result seemed to localize the formation of
