erroneously states, on page 222, that London and Wise published 

 " The Retired Gardener," which is a translation of " Le Jardinier 

 Solitaire " by the Sieur Louis Liger of Auxerre. This is certainly not 

 the fact. " The Retir'd Gard'ner " by London and Wise is a transla- 

 tion of two French books, " Le Jardinier Solitaire " by Dom Gentil, 

 a Carthusian monk known as Frere Francois, and " Le Jardinier 

 Fleuriste " by Louis Liger. Both books were enormously popular in 

 France and for many years enjoyed a high degree of public favour 

 there. 



We can only briefly indicate the nature of the remaining portion of 

 the work now before us. Garden design in the Netherlands occupies 

 over forty pages and there are some very quaint reproductions given 

 of Dutch gardens as they appeared in the Middle Ages. 



A review of German and Austrian gardens follows ; then we have a 

 chapter on Garden Design in Spain. The English landscape school 

 and its influence on the Continent also receive treatment, the whole 

 work forming a veritable mine of information, literary, historic and 

 artistic, upon gardens in all times and in all European countries. 



At the end of the volume which we leave with some little reluctance 

 is a bibliography of the most important books that have been published 

 on garden craft in Europe and the final pages are devoted to a capital 

 Index to the text and illustrations. 



We have much enjoyed Mr. Triggs' latest addition to horticultural 

 literature as we are conhdent many of our readers will when they 

 become the possessors of this very valuable and interesting volume. 

 It cm be strongly recommended as a standard work for the shelves of 

 any Horticultural Society's library. 



"Researches on Irritability of Plants." By J. C. Bose, M.A., 

 D.Sc, C.S.I. With 190 illustrations. 8vo., 376 pp. (Longmans, 

 London, 1913.) 7s. 6d. net. 



Dr. Bose is well known from his previous works on Plant-response. 

 The present volume is a further contribution on the same subject, but 

 treated by means of new methods and scientific implements, by the aid 

 of which not only was " light thrown on many obscure problems, but 

 also discoveries of several important and new phenomena were made." 

 The work contains twenty-six chapters, each replete with results of 

 experiments, intensely interesting to scientists. 



Response of plants is seen externally in many ways, as by turning 

 to the sun, transpira ion of water, &c, but it is to the internal effects, 

 not perceptible to the eye, that Dr. Bose has turned his attention. 

 Of the numerous problems to be solved are those to discover if the 

 responses of vegetable protoplasm are essentially the same as in 

 animals ; for in both " plant and animal alike there is the occurrence 

 of a fundamental excitatory protoplasmic change which finds external 

 expression in alteration of form." 



Having described the mechanism of his new " Resonant Recorder," 

 Dr. Bose gives the methods of stimulation, sent as a mechanical blow,
