Cur\es showing relation of pli to temperature and salinity (using halide values). The thick lines represent pH, thin lines represent temperature, and dotted lines halide values. Logarithmic values of the depths (fathoms) have been used. The changes of pH which were recorded were apparently chicH\- due to temperature as is shown by examination of the figures for depth samples. Figure 4 shows three typical curves, logarithms of the depths being used to reveal the surface changes more clearly. Only in samples olniously largely consisting ot Fraser River water do the pH and temperature cur\es cease to be parallel. With the exception of samples: obviously largely contaminated with Fraser River water, the simple relationship holds, where / is temperature expressed in degrees C, and Kp is a constant, 10(pH-7) t = Kp within the limits of error of the pH measurements. This is shown in Table X. 59.
