"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 in a most admirable 

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

 marshals his evidence.... We have tlie 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."
