OPINIONS OF THE PRESS. 



" The work before us, whose title we have given in full above, while modestly put forward as for the 

 use of young collectors, is one from which very few old hands would not learn a good deal worth 

 knowing."— The Canadian Entomologist. 



"The author has such a happy knack of popularizing his subject, so facile in laying a plain thing 

 in a plain way, so clear in his instructions, so hearty and enthusiastic in his work, that any one would 

 wish himself an ignoramus again to have the pleasure of such a teacher.'' — Science Qoesip. 



"The description of the various ways in which human astuteness manages to set at nought the 

 efforts of instinct for self-preservation cannot, we think, be without interest." — City Press. 



" Although professedly written for the assistance of youth ; children of a larger growth, in whom 

 the taste has developed into a study will find an inexhaustible field of instruction in its pages." — Observer. 



" Dr. Knaggs has put together a multitude of notes, the result of years of observation and experience, 

 and such as could never have been prepared by any mere compiler." — Scientific Opinion. 



" Codes of instructions for beginners in the most popular department of practical Entomology 

 oxiat in abundance ; but we have never met with one so complete and comprehensive a* this one «f 

 Dr. Knaggs's." — The Rock. 



" An original and well written portable manual." — Essex Standard.
