or somatogenic character in response to a definite 

 chemical stimulus. But the experiments went 

 much farther than this, for it was found that the 

 eye-defect produced thus artificially in the young 

 rabbits was inherited for at least six generations, 

 and actually became more and more strongly 

 marked as time went on. Moreover, it was shown 

 that the defect could be inherited through the male 

 parent alone, thus precluding all possibility of 

 intra-uterine affection. 



These wonderful results have not yet been 

 subjected to the full flood of destructive criticism 

 which is sure to be poured out upon them by the 

 scholiasts, but the work was done with so much 

 care, and the evidence is so plain and straight- 

 forward, that it is difficult to see how they can be 

 refuted. 



The next heading in our schedule is Biometrics, 

 which is the application of statistical methods to 

 biological problems. We owe the initiation of 

 this line of investigation in great measure to the 

 late Sir Francis Galton, and his work is being 

 assiduously followed up by the British school of 

 biometricians under the leadership of Professor 

 Karl Pearson. Unfortunately there appears to be 

 what almost amounts to a congenital incompati- 

 bility of temperament between the mathematical 

 and the biological faculties. It is rarely indeed that
