 admirable introduction to the study of heredity in the light of recent research. He writes clearly, 

 without dogmatism, he treats fairly both the Meudelian and the biometric schools." — Nature

 " A. new impression cannot fail to be -neXaovaeA. .. .Mendel's Principles of Heredity is already 

 a classic. It marks a position of stability towards which previous work is now seen to have 

 logically converged, and from which new and active research is to-day no less logically diverging. 

 The various waves of biological thought are constantly intersecting, mingling, and passing on 

 with altered rhythm, but it rarely happens that so many meet together at a nodal point as during 

 the last decade. ...As an analysis of that point, as a picture of how it has come into being, and as 

 a foreshadowing of happenings in the near futuie, Mendel's Principles stands alone, and it is 

 good to know that the generation of students now growing up cannot be cut oft from the posses- 

 sion of a book so full of inspiration." — Gardeners' Chronicle 



THE METHODS AND SCOPE 

 OF GENETICS

 Crown Svo. Is. %d. net. 



" Professor Bateson tells how Mendel's law works out with the colours of certain flowers, 

 moths, and canaries, and with colour-blindness in men and women. More than this, he describes 

 the outlook over this field of research in a manner that will greatly interest and attract all in- 

 telligent people, for, as he rightly says, ' Mendel's clue has shown the way into a realm of nature 

 which for surprising novelty and adventure is hardly to be excelled.' " — Morning Post
