BOOK EEVIEWS. 



"Mendelism." By Professor E. C. Punnett. Ed. 3. 8vo., 

 xiv + 176 pp. (Macmillan, London, 1911.) 5s. net. 



When the first edition of this httle book was pubHshed in 1905 

 .it immediately made its mark. It dealt in such a clear, and withal in 

 , such an accurate, manner with the subject, and was written in ^^o 

 pleasing a style, that it appealed to large numbers of those interested 

 in the principles of inheritance. 



The third edition has attained to more than double the bulk, and 

 many changes from the first have been made. New matter has been 

 accumulated and digested ; new light has been thrown on old investiga- 

 tions ; changes in the direction of simplification, and discoveries need- 

 ing new theories to explain them, have been made. 



Evidence of the working of the same laws has been obtained from 

 many different groups of living things, and the results of the con- 

 sideration of this evidence are written in this new edition no whit less 

 clearly or less accurately than in the first. We miss perhaps some- 

 thing of the attitude of the student which was evident in the first 

 edition, and see, perhaps, more of the attitude of the professor, but 

 of that one must not complain, for the author is evidently a thoroughly 

 convinced "Mendelian." We heartily recommend the book as a 

 reliable and readable account of the outcome of Gregor Mendel's work. 



"British Fungi, with a Chapter on Lichens." By G. Massee. 

 8vo., X -1- 551 pp. (Eoutledge, London, 1911.) 7s. 6d. net. 



The name of the author is sufficient recommendation of this book, 

 for no one is in a better position than he to write such a book, and 

 probably no one, at any rate of the present generation, has worked so 

 assiduously as he at the group. It will therefore suffice to indicate 

 briefly its contents. An Introduction dealing with the natural history 

 of fungi and the broad lines of their classification is followed by 

 descriptions of the species, and these are illustrated with admirable 

 coloured plates. 



Only the larger fungi are dealt with, of course, and but few of the 

 lichens, but the book is one that should be in the hands of all who 

 desire to know something of the fungi they meet with in their autumn 

 walks. 



"An Introduction to Vegetable Physiology." By J. Eeynolds 

 .Green, Sc.D., F.E.S. Ed. 3. 8vo., xxii + 470 pp. (Churchill, 

 [London, 1911.) 10s. 6d. net. 



Several modifications have been made in the present edition of this 

 j deservedly well-known book, bringing it into line with recent research 

 ' and adding to its lucidity or completeness.
