    From the curves of figure 28 or figure 29, table 8 is con¬ structed. Some of the columns of that table are obtained directly from the curves, the others by calculation, mak¬ ing use of the relations expressed by the following equa¬ tions : [H2C03] = pC02 X [H20] X 0.0726, (8) where [H20] B = 865 and [H20] s = 943, and PHS = 6.12 + log [BHC03]s - log [H2C03]8. (9) Fig. 29 Logarithmic Carbon Dioxide Dissociation Curves In equation 8 a small error is introduced if [H20]g be taken as constant. The mean value of this quantity is, as stated, about 943 and, since the variations for the ranges of the table in volume of cells and volume of serum are approximately two per cent, the variation in [H20]s (water per liter of serum) is about ±0.1 per cent, as the following calculation shows:
