This pamphlet was prepared for the region about Peoria, III., but contains much that will be of value elsewhere. It gives a brief account of the indigenous trees and shrubs best adapted to the locality, and the paper by Miss Smith treats of the insects which infest them, of which figures are given. Publications like this do excellent service in directing public attention to the cultivation of trees and the planting of forests.
Under the above general title Macmillan & Co. have published a series of small volumes containing lectures delivered at the South Kensington Museum during the loan collection of scientific apparatus last year. One of the volumes contains two lectures by Prof. Roscoe on "Technical Chemistry," the first treating of the manufacture of sulphuric acid, and the second of the alkali manufacture. In another volume are two lectures by Prof. Stokes, on "Absorption of Light and the Colors of Natural Bodies," and on "Fluorescence." The third volume of the series contains two lectures on the "Steam-Engine," by F. J. Bramwell. Finally, there is a volume entitled "Outlines of Field Geology," by Prof. Geikie. These lectures are all addressed to science-teachers, and not to popular audiences; hence they are rather technical, and possess an interest for the practical student of science rather than for the general reader. The prices are: for the first two volumes, 20 cents each; for the other two, 25 cents.
J. W. Bouton announces "Isis Unveiled: A Master-Key to the Mysteries of Ancient and Modern Science and Theology," by H. P. Blavatsky, Corresponding Secretary of the Theosophical Society. This work is announced as a philosophical study of Orientalism, by a native of Asia, whose life has been passed in the study of traditions, languages, literature, mythology, philosophy, and mysticism, of Eastern peoples, and who considers Oriental thought and history with reference to modern ideas. The work is to be issued in two large octavo volumes.
