EFFECTS ON ALCOHOLIC FERMENTATION 



207 



The relative effect of the rays from radium and from radio-tellur- 

 ium was ascertained from the following experiment. 



Experiment 85 

 The experiment was arranged as described for Experiment 84. 

 Observations of the volumes of gas evolved in fermentation are 

 recorded in the following table :
