    the presence of a preponderance of or of a greater partial pressure of carbonic acid, bicar- bonates may be formed at the expense of the diphosphates and the alkali compounds just mentioned; while, when partial pressure of car- bonic acid is lowest, a reformation of the di- phosphates and the alkali compounds will take place, and carbonic acid will be liberated from the bicarbonates. The investigations of Setschenow, Zuntz, Bohr, and Torup, however, make it appear probable that hemoglobin itself, even in the presence of alkalies, can loosely bind carbonic acid. Bohr found, in addition, that the curve showing dissociation of carbonic-acid hemoglo- bin, and that showing increase or decrease of carbonic acid in the blood, essentially corre- spond ; and hence Bohr and Torup ascribe con- siderable importance to the hemoglobin itself, rather than to its alkali compounds, in the for- mation of carbonic acid in the blood. More- over, hemoglobin possesses the ability to ab- sorb the two gases, oxygen and carbonic acid, both independently of each other and simulta- [6]
