 observed that it bore the familiar features of Dr. Engelmann, 

 that it was very expressive of a certain truth which has been 

 coming to me with greater clearness as the years go by. 

 After all, in our scientific work, it is personality that really 

 counts. 



On this occasion I venture to paraphrase the words of 

 Tennyson: "Better fifty years of science than a cycle of 

 superstition." What the great poet really meant when he 

 wrote the famous line was that it is better to have those qual- 

 ities of the intellect than those other less developed mental 

 aptitudes which are still so common in all of us.
