An Introduction to a Biology 



checked by the test of crucial experiment, can disentangle 

 the truth " ; x and appreciate the point of view of the bio- 

 meter marshalling his vast arrays when he contends that 

 it is " better to use the purely descriptive statements of 

 Galton and Pearson than to invoke the cumbrous and un- 

 demonstrable gametic mechanism on which Mendel's hypo- 

 thesis rests." 2 I do not see that we have any right to remain 

 blind any longer to the fact that the contradiction of their 

 respective theories is only apparent, and is due to the radical 

 difference in their points of view.
