 Kvcellent alike in matter, treatment, and illustration .... the complete

In reviewing a further volume *' Knowledge' ' says: — ''The work as a whole 

 i^ valuable not only for the excellence of its parts, but for its co-ordination, which 

 ..i'Ms at showing both the lievelopment of knowledge and its relation to the evolution 



■ )t the planet.*' 



Mr. E. B. Anderson, of Cambridge Road, Rathmines, Dublin, writes:— "The 

 wiirk is really very splendid, and most useful to a person who, although a specialist 

 in one branch of science, wishes also to have some knowledge of the other sciences. 

 In this connection your book supplies the want.' 



Mr. E. E. Bucklar, of Shamrock Villa, East Park Road, Leicester, writes: — 

 ■' I beg to state that I am ver\- plexsed with the book, which I certainly con>ider to 

 be the best of its kind. AVilhout doubi it supplies a long existent need. As a 

 medium for imparting scientific information in a simple manner it is unique. !Most 

 i '-riainly you may send on the remaining volumes. I shall await their advent with 

 c.iuerne>s."
