The Royal Natural History. Edited by Richard 

 Lyddeker, B.A., F.R.S. illustrated by 72 coloured 

 plates and 1,600 engravings. Second edition. 

 (London and New York : Frederick Warne and Co.. 

 1896-97.) In 72 weekly numbers, price 6d. each. 



This new edition of the Royal Natural History 

 is indeed a wonderful instance of modern cheap 

 publishing. Each number contains forty-eight pages 

 of letterpress, many engravings, and a coloured 

 plate. In this edition new coloured plates have 

 been added in some instances, such as for tigers, 

 leopards, etc. The letterpress has been revised 

 and brought quite up to date by the editor as 

 published. The work has reached its fifty-second 



a short general introduction to entomology, and 

 directions for identifying, prevention and eradication 

 of the pests. There are also some life-histories and 

 many excellent illustrations. There is a short 

 appendix containing several animals of allied classes 

 to insects, such as mites and centipedes. The 

 arrangement in treating with the subject is to select 

 the order of plants likely to be attacked, and then 

 to describe the insects to be expected.

 well worth its price, but we predict that it will 

 have to be largely augmented before the directory
