A Manual OF North-American Birds. By Robert Ridge- 

 way. Royal 8vo, pp. xi. — 631, plates 124. (Philadelphia : J. B. Lippincott 

 and Co. 1SS7.) 



This fine work was originally projected by the late Professor Spencer F. 

 Baird, and is based essentially upon the grand National Cabinet of American 

 Birds, which his energy, ability, and enthusiasm have developed from an 

 unpretentious nucleus to an unrivalled collection. It is intended to furnish a 

 convenient manual of North-American ornithology, reduced to the smallest 

 compass by the omission of everything that is not absolutely necessary for 

 determining the character of any given specimen, and including besides the 

 correct nomenclature of each species, a statement of its natural habitat, and 

 other concomitant data. 



The 124 plates contain 464 finely-executed outline drawings of the generic 

 characters. A fine portrait of Prof. Baird forms a frontispiece to the volume. 



Guide Pratique pour les Travaux de Micrographie, compre- 

 nant la Technique et les Applicationes du Microscope a I'Histologie Vegetale 

 et Animale, a la Bacteriologie, a la Clinique, a I'Hygiene. et a la Medicine 

 Legale. Par MM. Docteurs H. Beauregard et V. Galippe. Crown 8vo, pp. 

 vii. — 901. (Paris : G. Masson, 120 Boulevard Saint Germain. 1S88.) 



The authors of this treatise have set before themselves a difficult task — to 

 produce a book that shall be a miniature library of all subjects connected with 

 microscopy ; and though, perhaps, it would be hardly correct to say that they 

 have achieved perfect success, yet they have produced a work of great value to 

 the student. The first few pages are devoted to the optical and mechanical 

 arrangements and to the preparation of microscopic objects. The main portion 

 of the work consists of, we might almost say, exhaustive treatises on Vegetable 

 and Animal Histology. We have a very instructive series of sub-chapters on 

 the Cell, its contents and changes. Then there is another series that deals 

 with the interesting question of Bacteria, pointing out the practical way of 

 studying this, in the present day, burning question. In the same way, when 

 we come to Animal Tissues, we have excellent treatises on Milk — its deriva- 

 tives and their adulteration, Blood-Parasites, Hairs, etc. There is also a 

 valuable chapter on the organisms that are found floating in the air. The 

 work is fully illustrated with wood engravings, which, judging from those that 

 come within the range of our own knowledge, we can pronounce to be true to 

 nature and very effective. 



Practical Microscopy : A Course of Normal Histology for 



Students and Practitioners of Medicine. By Maurice N. Miller, M.D. Royal 

 8vo, pp. XV.— 217. (New York : William Wood and Co. 1S87.) 



This will be found a most useful work. It is divided into three parts : — 

 I •—Technology, in which the Microscope and Accessories are fully described, 

 with the method of preparing, cutting, staining, etc., tissues for microscopical 

 purposes; 2.— Structural Elements; and 3.— Organs, followed by Microscopi- 

 cal FormuLx. The illustrations— of which there are 126 — are photographical 

 reproductions of the author's own drawings and are very good.
