We do not know of any book in which so intelligent and so true an account of these things, which were the springs from which events issued, and which underlie all their currents, is to be found. The sympathies of the author are with the liberal party, with the party that labored for reform, but not for a republic, and whose hopes and plans were crushed by the horrible assassination of Rossi. It is one of the most calamitous results of a tyranny like that exercised at Rome, that it renders a gradual progress of reform at any time when it may be undertaken almost an impossibility, and sows the seed of inevitable violence and of revolution, which is apt to end, as in the Roman instance, in a return of despotism. The view given of the Roman revolution and republic of 1849 by the author of "Mademoiselle Mori" coincides in the main with that taken by Farini, and the other chief Italian statesmen of the present day; and its accuracy and good sense are confirmed by the course of recent events, not merely in Rome, but in other parts of Italy as well. It is vain to predict the future of a state so anomalous as that of Rome; but it is safe to say that the Romans learned much from their last revolution, and are learning much from its results, so that, when another opportunity arrives for them to gain some share of that freedom which Northern Italy has been so happy in securing, they will not repeat their former mistakes, and will not be found less competent for liberty than the Tuscans or the people of the Romagna. Perhaps the failure of 1849 may then turn out to have been a dark blessing; and the blood of those who fell on the Roman walls, and the tears of those who have wept in Roman prisons, may not have been shed in vain. The cause of Italy deserves the heartiest sympathy, and, if need be, a personal sacrifice on the part of every lover of liberty and of justice in the world. The question of Italian unity and independence is the most important that has been presented in Europe in our time. The issue involved in it is that of the advance or the degradation of a nation so noble that none can be called nobler,--of the rights of the many, as against the power of the few,--of the rights of thought, as against those of the sword,--of the establishment of those principles which do most to make life precious, as against those by which it is made vile and wretched. The last year has seen a part of the great work of freeing Italy accomplished. If Sardinia can but have time allowed her in which to knit her forces, if she can for a time escape from foreign attacks and from internal divisions, Italy is secure. Venice, Rome, and Naples will not long languish under the tyranny of Austrian, of priest, and of Bourbon.
