 in favor of our original hypothesis that decreasing the percentage of 

 protein in blood serum increases the conductivity of that serum.

Fig. 2. Changes in conductivity of 0.6 per cent NaCl solutions with increasing 

 concentration of gelatin (from 0.8 per cent to 6.5 per cent) at various hydrogen 

 ion concentrations. At pH 3.3, the specific conductivity X 10~* increases from 

 114.5 to 122. At pH 5.1, the conductivity decreases from 108.8 to 94.2. At pH 

 7.4 the conductivity decreases from 109.7 to 101.
