382 The Microscope. 



A Popular Zoology, by J. Dorman Steele, Ph. D., and J. W. P. Jcnks, 

 A. M., Professor of Agricultural Zoology in Brown University. A. H. 

 Barnes & Company, New i ork and Chicago. 1887. pp. 311). 



Steele's well-known " Foui-teen Weeks in Zoology," of which 

 the present volume is an enlarged edition, was published in 1872, 

 and immediately became the class-book in nearly every common- 

 grade school in the country. Fifteen years, however, have seen so 

 many changes in classilication and nomenclature, that in order to 

 bring the book up to the times, Professor Steele proposed a new 

 edition, but although he was able to read the MS. of the Popular 

 Zoology, his life ended before the work was given to the press. 



Both this and the former edition of the book were written by 

 Professor Jenks, whose life-long familiarity with the subject and 

 well-known ability as a teacher, render his work both reliable and 

 entertaining. In Po])ular Zoology, the student is not only put in 

 possession of names and facts, but he is taught how to observe, 

 collect, and, in a more than general way, how to make use of his 

 knowledge. The work has been entirely re-written, is fully illus- 

 trated, and in binding, paper and type is all that could be desired. 

 We predict its great popularity. 



Grasses and Foragk Plants; A Practical Treatise comprising their 

 Natural History; Comparative Nutritive Value; Methods op 

 Cultivation; Cutting and Curing; and the Management op Grass- 

 Lands IN THE United States and British Provinces, by Charles 

 T. Flint, late Secretary of Massachusetts State Board of Agriculture, etc., 

 etc. Revised edition. Boston: Lee & Shepard. Detroit: John Macfarlane. 



In glancing over the pages of this work one is impressed with 

 the highly scientific tone of its contents, as well as their eminently 

 practical nature. The chapters on sowing grass-seeds, time and 

 mode of * cutting grass for hay, curing hay, and the general treat- 

 ment of grass lands, show the author to be a practical farmer as 

 well as a scientific botanist. Although scientific farming is often 

 made light of by those who may be termed "experienced farmers," 

 and perhaps often brought into disrepute by the prodigal expendi- 

 tures of the dilettante, still, we must look to it for the rapid 

 advancement of remunerative agriculture. What scientific methods 

 have done and are doing for other industrial pursuits, they will do 

 for agriculture, and the sooner all farmers learn this the richer they 

 will be. Mr. Flint's book is of the highest rank, and no agricultur 

 ist can afford to be without it. 



Sexual Impotence in the Male and Female, by Wm. A. Hammoud, 

 M. D. Detroit, Mich., 1887. Geo. S. Davis. Cloth, |3. 



This work is a vigorous treatise upon a very important subject 



by an able and experienced writer. We commend it to physicians.
