Calculation following Schmidt-Nielsen's formula (K as in Column 4) 



dx 

 gave no better result. Next we tried — = K(a — x)^ (as in Column 5) 



dt 



dx 

 and— = K{a — xY (as in Column 6) . The latter gave a constant 

 dt 



series. The destruction of the enzyme is probably due to other causes 



(substances washed out by exosmosis (?)).
