PRESS OPINIONS 



Nature. — " We all know books of science which we ought to read with pleasure, but 

 to which we turn with shrinking. Full, perhaps, of new facts and ideas, they are so 

 expressed as to bore consumedly. " Heredity " belongs to another category. He who 

 runs may read, even if he be a beginner, and he who reads will probably not cease to 

 run until he has traversed the last page." 



Science Progress. — " This is certainly the best modern book on heredity to recommend 

 to the student and the intelligently curious." 



Knowledge. — " May be regarded as the standard work of reference on this subject. 

 As a judicial summary of an exceedingly difficult and controversial subject it is masterly, 

 while in the matter of clearness of exposition it has no rival."

PRESS OPINIONS 

 Spectator. — " A most admirably conceived exposition which does not seek merely 

 to attract us by turning marvels, at once outstripping our imagination and humbling 

 our conception, into cheap popular gazing-stocks, but rather supports its unfailing charm 

 by the legitimate interests — pointed here into a fascination that may arrest even an 

 habitually desultory reader — of science at once genuinely and delightfully taught." 



Daily Telegraph. — " A valuable addition to ' The Progressive Science Series '. . . . 

 Those readers who would realise how the world of science is passing to a new stage of 

 thought and progress we must refer to Mr. Soddy's most engaging volume, which has 

 not been surpassed in interest for many a day."
