FASHION IN SCIENCE 113

 bias they are giving to aspirants to research is

 culs de sac. Thirty years ago it may have been

 evolution by detailed and minute comparison of 

 the morphology of plants. We know to-day that 

 the aspiration will not be realised in this manner. 

 Again some critics might urge that historical

The function of pure science is to pursue useful 

 knowledge; the duty of the leaders of science is
