The volume thus produced by these distinguished authorities 

 affords an admirably thorough and comprehensive view of the 

 present condition of the broad field of science in which Darwin

 rather than for the specialist, it commends itself to a wide circle 

 of readers. w. r. c. 



2. Les Zoocecidies des JPlantes oV Europe et du JBassin de la 

 Med iter r an'ee ; par C. Houakd; 2 vols., pp. 1247, with 2 plates 

 and 1365 text-figures. Paris, 1908 (Lib. sci. A. Hermann). — 

 This great work consists of a descriptive catalogue of all the 

 varieties of malformations, or galls, which are caused by animal 

 parasites on plants growing in Europe and the Mediterranean 

 region. The list includes 6239 different kinds of galls. Most of 

 these are briefly described, and several hundred are illustrated. 

 These galls are produced by nearly 1200 species of insects and 

 268 species of arachnids. Such malformations are found on a 

 few species of Cryptogams, and on more than 2000 varieties of 

 flowering plants. Among the latter the oaks alone have more 

 than 800 different kinds of galls. The plants are arranged in 

 systematic order and their animal parasites indicated by name so 

 far as known. w. R. c.
