Table XY gives the results of appljing this method of cal- 

 culation to the experimental data for cadmium iodide previously 

 recorded in Table YIII. It is evident that the magnitude of 

 the active fraction decreases with the iodine concentration, 

 which is entirely natural since the transformation of a part of 

 the simple molecules into a new substance (tri-iodide) would 

 * Found b}" extrapolation.
