and Geology. There are 58 well executed engravings, besides 5 fine 

 photographic plates. We think that PL IV., a piece of red Marine Alg^ 

 (Plocamium rubrum), printed in natural colours, by one single operation, 

 is the most perfect example we have met with. 



Wild Flowers and Where they Grow. By Amanda B. 



Harris, with 60 illustrations by Miss L. B. Humphrey ; pp. 160. (Boston : 

 D. Lothrop and Co.) 



This book is written in a bright, popular style, with vivid recollections of 

 a child's delight in the beauty and abundance of wild flowers. It is, however, 

 a matter for regret that only the popular names of the flowers are given, for as 

 these appear to differ very considerably in " New " and " Old " England, it is 

 difficult to identify them. The work is handsomely bound, printed, and got 

 up, and the plates are charming. 



Plant-Life on the Farm. By Maxwell T. Masters, M.B., 



F.R.S. ; pp. 132. (New Vork : Orange, Judd, and Co., 1885.) 



In the little book before us the Author gives an outline of the physiology 

 or life-history of plants, of the way in which they are affected by circumstances 

 under which they exist, and of the manner in which they in their turn react 

 upon other living beings, and upon natural forces. The most practical part of 

 the book treats of the comparative values of different manures, and their 

 effect on the various grasses and cereals, illustrated by experiments made at 

 Rothamstead. 



The Botanical Atlas. A Guide to the Practical Study of 



Plants, containing representatives of the leading forms of Plant Life. By D. 

 McAlpine, F.C.S. Two Vols. : \o\. I., Phanerogams ; Vol. II., Crypto- 

 gams. (Edinburgh : W. and A. K. Johnson, 1883.) 



The object of the Author in preparing these two truly magnificent 

 volumes, is to provide a guide to the practical study of Plants ; the examples 

 selected are always of the commonest kind, selected from every readily 

 available source. In the volume devoted to Planerogams, the flower and its 

 various parts passing into fruit and seed are mainly considered, coloured 

 dissections being given. In the Cryptogams a similar course is adopted, and, 

 as the figures of every plant, or section of a plant, are represented in their proper 

 colours, the student cannot fail to find these books most helpful in his 

 botanical pursuits. 



Each volume (Atlas folio) consists of 26 coloured plates, and contains 

 an immense number of figures, with a page of letterpress descriptions opposite. 



We feel that we cannot recommend these volumes too strongly to our 

 Botanical friends. 



Your Plants. Plain and practical directions for the treat- 

 ment of Tender' and Hardy Plants, in the House and in the Garden. By 

 James Sheehan ; pp. 79. (New Vork : Orange, Judd, and Co., 1885.) 



A useful little book, written professedly for Amateurs, giving clear and 

 easy directions for the culture, planting, grafting, pruning, etc., of greenhouse, 

 garden, and window plants ; the making of Wardian cases, etc. Mr. Sheehan 

 exposes the popular fallacy of supposing it to be unhealthy to keep plants in a 

 room ; he says the amount of carl)onic acid discharged at night from two dozen 

 large plants, will not equal that exhaled by one infant sleeper.
