sometimes used to work on a mathematical problem 

 for hours or days. Many would give it up. A few of the 

 class would take the answer from the book, and in an

 Such students, it is needless to say, never gained the 

 respect of either class or teacher or themselves. They

 fallacy of it had been discovered. In life's school such 

 were the men just named, and the distinguishing fea- 

 ture of their lives was that they were students and 

 learners to the last. 



Of this group of scientific workers, Alfred Russel Wal- 

 lace alone survives, aged eighty-two at this writing,

To some it is an anomaly and contradiction that a lover 

 of science, exact, cautious, intent on certitude, should
