This new edition of Ratzeburg’s work is to be an altered and improved 
one. The first division now issued is an introduction, giving such bio¬ 
logical information as is considered by the editors to bear on Ratzeburg’s 
subject—the insects injurious to trees. It contains a large amount of 
well-selected information, amongst which will be found a division 
(pp. 164-182), in which the fungi destructive to insects are discussed; this 
division has been supervised by De Bary.
