ARCANA of SCIENCE, and ANNUAL REGISTER of the USEFUL ARTS for 1831.

"This is the fourth annual volume of a most useful compilation of the
various discoveries in science or inventions of art during the preceding
year. The volume commences, very properly, with an abridgment of what
may be termed the greatest work of art which has distinguished the
present century--the Liverpool and Manchester Railway. Various other
improvements in the different departments of the arts which have
appeared in the several scientific journals of the last year, are here
presented in a condensed form, so as to render the volume, in reality,
an excellent book of reference. The object of the editor seems to have
been that of blending entertainment with valuable information, the work
being illustrated by many neat engravings relating to the popular
branches of science. The volume, therefore, contains a very interesting
compendium of information for young people."--_New Monthly Magazine._
