An Introduction to the Study of Seaweeds. By George 



Murray, PMx.S.E., F.L.S., etc. Crown Svo, pp. xvi. — 271. (London: 

 Macmillan and Co. 1895.) I'nce 7/6. 



Modern research has completely changed the whole aspect of the study of 

 seaweeds. In the work before us the author has described only what he has 

 personally verified by examination, or by the inspection of the original account. 

 The arrangement of the sub-classes is in the following order : — The Phiiopliy- 

 ccir, with its familiar forms of sea-wracks and tangles form the first sub-class ; 

 the Chlorophyceie and Diatomacecv follow ; the Rhodophycea next make a 

 series by themselves ; and lastly, the simple Cyanopliycea. There are eight 

 beautifully coloured plates and eighty-eight other illustrations. 



Handbook of Grasses. By William Hutchinson. Cr. 8vo, 

 pp. 92. (London : Swan Sonnenschein & Co. 1895.) Price 2/6. 



Treats of the Structure, Classification, Geographical Distribution, and 

 Uses of Grasses. It also describes the British Species and their Habitats, and 

 is an endeavour to popularise the study of grasses, the peculiarities of their 

 structure, and terms employed in describing these plants are carefully explained ; 

 the chapter descriptive of the British species and their habitats is arranged with 

 special regard to convenience in field work. Definite information is also given 

 regarding the geographical distribution of grasses and their vast economic 

 importance. A very useful book. There are 40 good illustrations in the text. 



Analytical Key to the Natural Orders of Flowering Plants. 

 By Franz Thonner. Cr. Svo, pp. 151. (London : Swan Sonnenschein and 

 Co. 1895.) Price 2/- 



In this work the author chooses, for the determination of genera, distinc- 

 tive features, preferring those which are visible to the naked eye at the time of 

 flowering. 



Ferns : British and Foreign. By John Smith, A.L.S. New 

 and enlarged edition. Cr. Svo, pp. xv. — 450. (London : W. H. Allen. 

 1895.) Price 7/6. 



This useful work gives the history, organography, classification, and enu- 

 meration of the species of garden ferns, with a treatise on their cultivation — e.g.. 

 Special or pot cultivation ; Natural cultivation ; Wardian-case cultivation and 

 propagation. There are also a General Index of Genera, Species, Synonyms, 

 and an Index of Special Terms, and a great number of illustrations. 



Random Recollections of Woodland, Fen, and Hill. By 

 J. W. Tutt, F.E.S. Second edition. Crown 8vo, pp. 256. (London: 

 George Gill and Sons. 1895.) Price 2/6. 



Mr. Tutt has given us a delightfully written little book dealing with natural 

 history subjects and country scenery. We can cordially recommend it as a 

 reading book for our young friends, and trust it will lead many of them to 

 observe for themselves some of the wonderful things in Nature by which we 

 are surrounded. There are more than 100 good illustrations. 



Half-Hours with the Stars. By Richard A. Proctor, B.A., 

 F.R.A.S., etc. New edition, revised and corrected. 4to. (London: W. H. 

 Allen. 1896.) Price 3/6. 



We have, to give the full title, A Plain and Easy Guide to the Knowledge 

 of the Constellations, showing in 12 maps the position of the principal star- 

 groups night after night throughout the year, with introductions and a separate 

 explanation of each map for every day in the year. The maps are very good, 

 and so plain that we believe the student could not possibly misinterpret them, 

 even if he paid no attention to the accompanying letterpress.
