MIMICRY IN BUTTERFLIES 



By R. C. PUNNKTT. F.RS., Arthur Balfour Profussor,of Genetics in the 



University of Cambridge. Royal 8vo. Buckram. With 16 plates. 15s net. 



" Though much has been written on the subject of late years, there has not heretofore been 

 any single comprehensive book dealing with it in the light of the latest knowleilgo. This lack 

 Professor Punnett has admirably supplied. Primarily he briuirs to bear on tlie question the 

 arguments of Mendelisni... .Professor Punnett collates the facts from various sources, and 

 presents them clearly and in due proportion. His explanations are helped by excellent coloured 

 plates illustrating the most important examples of mimicry from ilifferent parts of the world.... 

 The whole subject is still beclouded. We have onlj' the beginnings of knowledge. But at least 

 in Professor Punnett's treatise we seem to see the foreshadowing of something like a founda- 

 tion of solid fact in place of what has heretofore been a rather airy structure of fascinating 

 guesswork." — Times

By L. DONG ASTER, Sc.D., Fellow of King'.s College, Cambridge. 

 Demy 8vo. With frontispiece in colour and 22 plates. 7s 6d net. 



" The whole book is worthy of careful study, and it shows the sound progress which is 

 being made by the scientific school at the University of Cambridge. ... It is well illustrated." 



Athenaeion 

 "In this little book Dr Doncaster has given an account of our present knowledge of the 

 causes which determine the sex of offspring. He has handled the subject iu a most admirable 

 manner. It would be difficult to praise too highly the clear and impartial way iu which he 

 marshals his evidence.... We have the greatest pleasure in commending this book to our readers 

 as giving the ablest, clearest, and tersest account of the sex-problem which we have seen."

" Mr Doncaster has performed a remarkable feat in condensing into so small a space such an 

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

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