If we put A'i = . 000481 and /v,o = . 00859 we obtain as the 

 amount of resistance the values given in Table III. and plotted as a 

 broken line in Fig. 3 (the values obtained experimentally are plotted 

 as a continuous line). 



Fig. 3. Curve of electrical resistance of Lamiuana in 65 NaCl + 35 

 CaCl; ( ), the trial curve (— ) calculated from the veloc- 

 ity constants K^ = .000481 and K2 = .00859, and the theoretical curve 



( ) calculated from the velocity constants K^ = .000482 and Kn = 



.00859. 



Evidently the curve of resistance,^ as calculated, agrees^ fairly 



8 The agreement in other mixtures may be seen in Table III. and Figs. 



6-9. 



9 The fact that the theoretical curves can not be made to assume any 

 desired form but can only be varied within certain limits shows that if they 

 fit the experimental curves they express processes similar to those which 

 take place in the tissue.
