Microscopical Diagnosis. By Chas. H. Stowell, M.D., and 



Louisa Reid Stowell, M.S. Illustrated with 128 engravings and 47 figures 

 on stone, 8vo, pp. 250. (Detroit: Geo. S. Davis. 1882.) 



Although this is not actually a new edition we are pleased to have the 

 opportunity of noticing it. The authors, who are editors of the well-known 

 "Microscope," now published at Ann Arbor (U.S.A.), have endeavoured to 

 show in the first part of the work that the Microscope is absolutely necessary 

 in the diagnosis of many forms of disease. Part II. is devoted to Vegetable 

 Histology, in which Wheat, both in the grain and the straw, is largely dealt 

 with. Part III. contains hints on the preparation and mounting of Micro- 

 scopic objects, and the whole work contains much useful information. 



Album of Natural Woods. A very handsome album, 



consisting of 40 stout cards, each containing three beautifully thin sections of 

 the more important European woods, the size of the specimens being i| in. by 

 4^ in. These are cut longitudinally, transversely, and tangentially, and are 

 open to inspection on both sides. In addition to the scientific name, they are 

 named in English, French, and German. The whole is enclosed in an elegant 

 Mosaic Wood cover, which is of itself a work of art. 



The album may be obtained of M. Wilmersdorffer, 72, Finsbury Pavement, 

 E.G., the price being 25s,

 (London : Religious Tract Society. 1885.) Price 6s. 6d. 



Since the publication of the first edition of this capital little book, many 

 additions to our knowledge of Fossil Animals and Plants have been made, 

 many new species of which are here described. New facts are also related 

 concerning many species previously known. The volume is illustrated with 

 192 wood engravings. 



Talks Afield about Plants and the Science of Plants. By 

 L. H. Bailey, junr. Cr. 8vo, pp. ix. — 178. (Boston, U.S.A. : Houghton 

 Mifflin and Co. 1885.) Price $1. 



This interesting little book is written for those who desire a concise and 

 popular account of some of the leading external features of common plants. 

 It treats first of the Fungi, Algse, Lichens, Mosses, and Ferns : then of some 

 of the more interesting features of the flowering plants, the Flowers and 

 Stems, Classification and Fertilisation, being well described. The volume 

 closes with a chapter on plant names ; it is well illustrated. 



Our Insect Enemies. By Theodore Wood. pp. xii. — 220. 



(London : Society for Promoting Christian Knowledge. 1885.) Price 2s. 6d. 

 Our readers will remember that in our last volume we called the attention 

 of our readers to " Our Insect Allies," to which this forms a companion volume 

 by the same author. With the exception of the Aphides, the Author has 

 treated the insects described according to their system of classification, and not 

 with respect to the particular crops which they frequent, but to the Aphis four 

 chapters are devoted. The author directs attention to the invaluable assistance 

 rendered by the smaller birds, amongst which we find included the much 

 maligned sparrow.
