A Manual and Dictionary of Flowering Plants and Ferns. 

 In Two Vols. By J. C. Willis, M. A. Crown 8vo, pp. xiv. — 224 ; xiii. — 429. 

 (Cambridge: The University Press. 1897.) Price 10/6. 



The aim of the author has been to prepare a book to supply, within a 

 reasonable compass, a summary of useful and scientific information about the 

 plants met with in a botanic garden, or museum, or in the field. He gives such 

 information as is required by any but specialists upon all plants usually met 

 with, and upon all those points — morphology, classification, natural history, 

 economic botany, etc. — which do not require the use of a microscope. 



Vol. I. describes the Outlines of the Morphology, Natural History, Classi- 

 fication, Geographical Distribution, and Economic Uses of the Phanerogams 

 and Ferns ; and Vol. H. gives the Classes, Cohorts, Orders, and Chief Genera 

 of Phanerogams and Ferns alphabetically arranged under their Latin names. 



The Botanist's Pocket-Book. By W. R. Hayward. 7th 

 edition, i2mo, pp. xxxvi. — 226. (London: G. Bell and Son. 1892.) 



This very useful little book contains in a tabulated form the Chief Charac- 

 teristics of British Plants, with the botanical name, common name, soil or 

 situation, colour, growth, and time of flowering of every plant arranged under 

 its own order. There is also a good index, in which reference is given to the 

 volume and page of Sowerby's Botany, in which a much fuller description of 

 the plant will be found. 



The Elements of Botany. By Francis Darwin, M.A., M.B., 

 F. R.S., etc. etc. Cr. 8vo, pp. xvi. — 235. (Cambridge and London: The 

 University Press. 1896.) Price 4/6. 



The fourteen chapters constituting this volume of the Cambridge Natural 

 Science Manuals give the substance of the Botanical Lectures delivered to the 

 Cambridge medical students ; whilst in an appendix is given the details of the 

 Practical work which accompanies the lectures. In these lectures the Bean, 

 Ranunculus, Silene, Chrysanthemum, etc., are used to illustrate floral struc- 

 ture ; Caltha for the ovule ; Helleborus for the leaf ; and the Pear, Gooseberry, 

 Sycamore, etc., for the fruit. In the same way Yeast and Spyrogyra are made 

 use of to illustrate nutrition and the general structure of plant-cells ; and 

 Mucor, Spyrogyra, and Pteris illustrate reproduction. There are nearly 100 

 good illustrations. 



Practical Physiology of Plants. By Francis Darwin, M.A., 

 F.L.S., and the late E. Hamilton Acton, M.A. Second edition. Cr. 8vo, 

 pp. XX. — 340, (Cambridge and London : The University Press. 1895.) 4/6. 



This is another of the Cambridge Natural Science Manuals, and consists of 

 such a selection of experimental and analytical work as appears suitable for 

 botanical students. Part I. deals with General Physiology in a somewhat ele- 

 mentary manner ; Part II. treats a particular department of Physiology in a 

 more special manner, and pre-supposes a greater amount of knowledge on the 

 part of the student. There are 45 illustrations. 



Maladies des Plantes Agricoles et des Arbres Fruiteres et 

 Forestiers causees par des Parasites V6getaux. Par Ed. Prillieux. Vol. I., 

 8vo, pp. xvi. — 421. (Paris: Libraire de Firmin-Didcot and Co. 1895.) 



This work is the outcome of the author's twenty years' study and teaching 

 of Economic Vegetable Pathology. He considers plant diseases to be due to 

 changes of normal physiological functions produced either by unfavourable con- 

 ditions or by the action of parasitic organisms penetrating the tissues. The
