In the past three years the progress of Mendelian analysis has been very 

 rapid, and the author has endeavoured in a series of brief Appendixes to 

 acquaint the reader with the nature of the principal advances made. 



"This tliird edition shows how rapid has been the progress of Mendelian analysis. It deals 

 with heredity of colour, heredity and sex, gametic coupling and spurious allomorphism, double 

 flowers, evidence as to Mendelian inheritance in man, biological conceptions in the light of 

 Mendelian discoveries and practical application of these principles. An appendix contains a 

 biographical notice of Mendel and translation of his papers on hybridization and hieracium. 

 The work is beautifully illustrated." — Chicago Medical Journal 



"A new impression cannot fail to be vielcomei.... 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 future, Mendel's Principles stands alone, and it is 

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

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