This last division, however, is one of the few unfinished windows of his Aladdin’s palace, for, out of the six volumes which it was to contain, two only were written before death intervened. These two works, the “Physiologie du Mariage” and the “Petites Misères de la Vie Conjugale,” are a series of duos between husband and wife, augmented at times by the tenor notes of the _amant._ The first is dedicated to the reader, and contains the deceptions of the husband; the second, those of the wife. At once malicious and diabolically witty, these two books are as delicately analytical as the deductions of Leuwenhoeck and Swammerdam, and abound with that peculiar though refreshing condiment which is generally known as Gallic salt. It is to be regretted that these two books, the first of which was published at the outset of the author’s career, and the second towards the close of his life, were not strengthened and augmented by the others with which he proposed to accompany them, and whose subjects and titles—namely, “Anatomie des Corps Enseignants,” “Pathologie de la Vie Sociale,” “Monographie de la Vertu,” “Dialogue Philosophique et Politique sur la Perfection du XIXe Siècle”—have alone descended to us; for this vein of literary treasure can never be profitably worked save by another Balzac or a modern Aristophanes. It was in 1844 that Balzac said, “The first half of the present century will be found to have been greatly influenced by four men,—Napoleon, Cuvier, O’Connell, and myself. The first lived on the blood of Europe, the second espoused the globe, the third became the incarnation of an entire race, while I shall have carried a complete society in my brain.” Though almost another half century has now elapsed since these words were uttered, it would seem that the influence which he was then conscious of exerting is even more vigorous than before. The characters which he painted formed, it is true, part of a Paris now dead and forgotten, but the types have survived, and the lessons which he deduced therefrom are as eminently instructive now as they were in the days when he wrote; and while, taking the world at large as the groundwork of his edifice, man was necessarily but the detail, he has, in his description thereof, painted him in every phase,—consequent and inconsequent, neither completely good nor completely vicious, logical at times, and sometimes great, but incessantly opposing his own interests to the laws of society in that gigantic struggle of customs and sentiments which is as inconsistent to-day as it was fifty years ago.
