THE Nineteenth Volume of the American Almanac is now offered to the public. Unwearied pains have been taken to collect full and varied information concerning the complex affairs of the general and state governments; and a mass of documents has been digested relating to the government, history, finances, legislation, public institutions, and internal improvements of the United States. It is believed that the present volume is equal to its predecessors in fulness and accuracy, and that it will sustain the high character of the American Almanac as a trustworthy manual for reference, and a full repository of useful knowledge.
The Astronomical Department has been, as usual, under the direction of Professor Peirce, whose high reputation is a sufficient guaranty of the completeness and accuracy of the computations. The articles upon the observatory at Washington and the great telescope at Cambridge, show the advantages that have resulted thus early to science from the wise forecast of the general government, and the generous munificence of the citizens of Boston. Another article gives the places in which Pingré's predicted comet of 1848 is expected to appear. The Meteorological information embraces points in all parts of the United States; and tables have been added, showing the flowering seasons, and days and depths of snow, for a series of years in several places. Such tables are valuable; and it is desirable that those who have kept them should forward them to the editor for publication. The table of latitudes and longitudes, kindly furnished for the American Almanac by Major Graham, and received too late for insertion in the body of the work, has been appended to it, and contains new and important geographical information.
In another part of the volume will be found an abstract of the laws of the several states concerning imprisonment for debt, which has been prepared with great care, and is more complete than any other yet published. The chapter upon the Patent Office and the laws concerning patents will show the inventive genius of our countrymen, and point out the steps necessary to secure the inventor in his rights. The history of the Electric Telegraph will be curious and interesting to all readers. The chapters upon the several Departments are full and accurate, having been corrected at
