For that reason, as was anticipated, the dense egg yolk undergoes an en- tirely different change in hydrogen-ion concentration. There is a gradual rise from slight acidity, of about pH , to an alkalinity of about pH near the end of the incubation period (Fig. 1 B). Then the pH values decrease slightly before the time of hatching. The data for all species follow the same general trend of change. This again is in close agreement with data published by Shklyer (1937). pH 95 85 Z ui I 75
