        Similar experiment was performed by using Fe hydroxide precipitated on infusorial earth and dried.  The result was similar to the previous experiment except that there was a shift in temperature at which irregularity and broken lines appeared.  In general, it was also noticed that infusorial earth had an effect of increasing the number of active centers and increasing the activity of those centers.
