1394. Bower, F. O. Botany of the living plant, x + 580 p., U7 fig. Macmillan & Co. 

 London, 1919. — This book represents an expansion of the "Course of Elementary Lectures en 

 Botany" given in Glasgow University for 30 years. The object of the work is stated to 1 e 

 "that of presenting the plant as a living, growing, self-nourishing, self -adapt ing creature.'' 

 In developing a sequence of topics the author arranges his material in accordance with t he 

 idea that it is better to begin with the better known plants (those of larger size and generally 

 familiar) proceeding to those generally smaller and lesser known. Some physiological facts 

 are distributed throughout, but certain chapters (IV, the leaf; V, the root; VI, the water 

 relation; VII, nutrition, storage, and respiration; and VIII, growth and movement) cont 

 more of physiological significance. No citations of literature are included and no collateral 

 reading is suggested. There is a combined index and glossary of 32 pages. — B. M. Duggar.
