Economics of Mankind " we seem to hear the 

 voice of a Pennsylvania official rather than 

 the scientific master of economical princi- 

 ples. But, notwithstanding its faults, the 

 work is original, helpful, and invigorating, 

 and those who are concerned to note the 

 drifts of modern inquiry will be sure to find 

 it serviceable. 



The Microscope and its Revelations. 

 By William B. Carpenter, M. D., F. R. 

 S. Sixth edition. Illustrated by Twenty- 

 six Plates and Five Hundred Wood-En- 

 gravings. Philadelphia: P. Blakiston 

 & Co. 1881. Pp. 882. Price, 85-50. 

 The admirers of the veteran physiologist 

 Dr. William B. Carpenter will be gratified 

 to learn that his surrender of the registrar- 

 ship of the University of London, to which 

 he had given nearly a quarter of a century 

 of his life, was not the signal of retirement 

 from scientific labor. On the contrary, lib- 

 eration in one field has only led to greater 

 activity in another. His elaborate work on 

 the microscope has long been a standard for 

 practical students, and has well kept up 

 with microscopical improvement and prog- 

 ress. In preparing the fifth edition the 

 pressure of official duties upon his time made 

 it necessary to call in assistance in getting 

 ready certain parts of the work. But, be- 

 ing recently more at liberty, he has rewrit- 

 ten those parts, and has devoted himself to 

 the task of thoroughly revising and much 

 extending the whole treatise in this sixth 

 edition. We have spoken of former editions 

 of the book in terms of strong commenda- 

 tion, and an examination of the present 

 has only served to heighten our estimate of 

 its excellence. It is encyclopedic in scope, 

 and profusely and elegantly illustrated. 

 The ease and clearness of Dr. Carpenter's 

 style are well known, and no book that he 

 has written better illustrates these qualities 

 than " The Microscope." There is another 

 feature of the work that adds greatly to its 

 popular value the large amount of inter- 

 esting information in each department of 

 natural history, which is made a subject of 

 microscopical study. While 266 pages are 

 devoted strictly to the construction, forms, 

 properties, and manipulation of the instru- 

 ment, more than 600 pages are given to its 

 applications in the living world. This great- 

 ly enhances the interest of the work, and 



- it a completeness possessed by no 

 other microscopical manual. Everj 

 who has a microscope will need also Dr. 

 Carpenter's book to get the most out of his 

 instrument; and every one who has tin- 

 book will be certain to want a microscope.
