Economics of Mankind" we seem to hear the voice of a Pennsylvania official rather than the scientific master of economical principles. 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-Engravings. Philadelphia: P. Blakiston & Co. 1881. Pp. 882. Price, $5.50.

The admirers of the veteran physiologist Dr. William B. Carpenter will be gratified to learn that his surrender of the registrarship 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, liberation 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 progress. 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, being recently more at liberty, he has rewritten 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 commendation, 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 interesting 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 instrument, more than 600 pages are given to its applications in the living world. This greatly enhances the interest of the work, and gives it a completeness possessed by no other microscopical manual. Every who has a microscope will need also Dr. Carpenter's book to get the most out of his instrument; and every one who has the book will be certain to want a microscope.
