Works on the German Revolution and German Politics.--An excellent book on the Prussian revolution is now being published at Oldenburg. It is from the pen of Adolf Stahr, a writer of remarkable force and clearness. He belongs to the party most bitterly disappointed by the turn affairs have taken in Germany. We mean the democratic monarchists, who labored under the illusion that they might see Prussia converted into a sort of republic with a hereditary chief, like Belgium. They desired a monarchy, with a parliament elected by universal suffrage, and democratic institutions of every kind. Stahr's book breathes all the bitterness of their rage at the success of absolutism in snatching from them every slightest vestige of hope. His book is published serially, four parts having already been issued. As a record of facts it deserves the praise of great industry and lucidity in collection and arrangement, while on every page there glows in suppressed eloquence the indignation of a generous and manly heart. Of course Stahr cannot be called a historian in the usual sense of the term. He is rather a political pamphleteer, maintaining at length the ideas and chastising the foes of his party. Another and a more permanently valuable work on this subject is the _Revolutions-Chronik_ (Revolutionary Chronicle) of Dr. Adolf Wolff, published by Hempel of Berlin. This is a collection of authentic documents, such as proclamations, placards, letters, legislative acts, &c., connected with the revolution. They are not only arranged in due order, but are combined with a clear and succinct narrative of the events and circumstances to which they relate. We know of no man more competent than Dr. Wolff to the successful execution of so important an undertaking. Without being a partisan, his sympathies are decidedly on the popular side, and the clearness of his judgment cannot be blinded by any of the feints and stratagems in which the period abounded. He is now engaged upon the revolution in Prussia, but intends to treat all the manifestations of the time throughout Germany in the same thorough and reliable manner. His work will be invaluable to future historians of this eventful period; at the same time it reads like a romance, not only from the nature of the events, but from the spirit and keenness of the style.
