The Intellectual Observer. January to March, 1864. A monthly journal

of science is, as may be supposed, of a more popular character than even a Popular Science quarterly,—that is to say, the articles are more various 1.x• point of subject, and slighter in point of treatment. It is certainly one Ed the features of the present day that papers on "The Dentition of British Mofluaes," and on "Mosses, Grimmia, and Schistidium " attract the public, and doubtless it is a very healthy feature. We must call attention to a suggestive Utile paper on "Insanity and Crime" in the March number.
