as a reliable representative of the supposed type " (p. 37). " We 

 may conclude that systematic species, as they are accepted 

 nowadays, are as a rule compound groups" (p. 38). These 

 quotations can hardly be interpreted as an insistence upon the 

 dictionary definition of a systematic species. 



Anyone who holds that the term species cannot be given a 

 definition acceptable to all systematists has returned to a " medi- 

 aeval " type of reasoning (p. 362), and taxonomists may now 

 choose from arropic, ropic, subsexual, semisexual, sexual, super- 

 sexual, symbasic, porric, stenic, linic, and clonic species (p. 389 

 et scq.). 



Typographical errors are rare, but on p. 234 it seems that 

 " /;//;'rtspective " should be read " //^//vzspecific." 



The lack of qualitative variations in such species as, c. g., Liri- 

 odendyo)i Tidipifera, or in species of the diatoms, which have 

 persisted unchanged through many geological epochs, and the 

 coexistence of closely related species without isolation, environ- 

 mental or physiological, are some of the problems which seem 

 more difficult of solution on the basis of " kinetic evolution " 

 than otherwise. 



Emphasis upon the idea of kinetic variation in organic evolu- 

 tion is a distinct service, and the idea is of increasing interest in 

 the light of the recent revelations of physical chemistry, point- 

 ing strongly to the evolution of the chemical elements by spon- 

 taneous transformations, that is, by a kinetic inorganic evolution. 

 The volume, however, does not refer to this closely related 

 phenomenon, and kinesis is discussed only with reference to the 

 realm of the organic. ^ Stuart Gager.
