I HAVE recently learnt from the publishers of the 

 ' International Scientific Series ' that they have made 

 arrangements with Sir John Lubbock to bring out in the 

 same series a work of his on Ants and Bees. Necessarily, 

 therefore, the material to be dealt with in his work will 

 to a large extent overlap that which is presented by my 

 chapters on the same insects ; but after consulting with 

 the publishers, and also with Sir John Lubbock, it has 

 seemed to me undesirable to omit these chapters on 

 account of the circumstances here stated. For, on the 

 one hand, the facts will not lose their value from being 

 twice told ; and on the other, it is desirable that the 

 present member of the Series should form in itself, so 

 far as its Author can make it, a complete resume of all the 

 more important facts df Animal Intelligence.
