Prof. Leeds, first, in an increased knowledge of what constitutes clean air, clean water, clean food, and clean environments, on the one hand, and on the other hand what constitutes filth in air, filth in water, filth in food, and filth in our environments, whether it be filth mineral, vegetable, or animal; and, secondly, in a better knowledge of the means of preserving cleanliness and repressing filthiness.

Annual Report of the Massachusetts State Board of Health. Pp. 520. Boston: A. J. Wright, State Printer.
The Massachusetts health reports, of which this volume is the eighth, form a series of public documents hardly equaled for the wealth of important information which they contain. The "Special Reports" on sanitary subjects comprised in the present volume are seven in number, and treat of "Pollution of Streams, Dispersal of Sewage, etc.;" "Sewerage;" "Sanitary Condition of Lynn;" "Registration of Deaths and Diseases;" "Growth of Children;" "Disease of the Mind;" and "Health of Towns." It is only by unceasing iteration of the lesson that filth is the great cause of disease, that the local authorities of towns and cities can be aroused to a sense of the danger of allowing insanitary conditions to persist. This lesson is inculcated with much force and thoroughness of research in some of the special reports named above.
Art-Education applied to Industry. By George Ward Nichols. Pp. 211. With numerous Illustrations. New York: Harper & Brothers. Price, $4.
The title of this work sufficiently indicates its purpose, which is to promote among the people an acquaintance with the principles of art as applied to the products of industry. The author would have these principles taught in all grades of our schools, and offers a scheme of a progressive course of art-instruction which he thinks might easily be adopted by directors of schools in this country. He gives an account of the present state of art-education in sundry European countries, and especially commends the programme of art-education in use in the public schools of Belgium. The work is profusely illustrated.
Linear Perspective. Part I. By F. R. Honey. Pp. 36. With Plates. New Haven: Judd & White. Price, $1.25.
The author of this little treatise, who is instructor in Descriptive Geometry and Perspective in the Sheffield Scientific School, here presents to the student, with all needed clearness, the leading principles of Linear Perspective in the space of a very few pages, and then proceeds to make application of them to perspective drawing. The course of instruction advances by easy steps from the construction of the perspective of a point situated in the horizontal plane to the construction of the perspective of a groined arch and its shadows, and of a spiral stairway.
Annual Record of Science and Industry for 1876. By Spencer F. Baird. Pp. 845. New York: Harper & Brothers. Price, $2.
The "Annual Record," which from the first has been recognized as the very best work of its kind anywhere published, continues to give evidence of the skill and care of its editor. The volume for 1876 contains some notable improvements on all its predecessors. One valuable feature now added is the index of authors and subjects, appended to the "General Summary." Another is the prefixing of the names of Prof. Baird's principal collaborators to the chapters of the "General Summary," written by them. The chapter on "Astronomy" is by Prof. Holden, that on "Meteorology" by
