As a domestic occurrence, nothing could more contribute to Bonaparte's happiness than his union with Maria Louisa. He was wont to compare her with Josephine, by giving the latter all the advantages of art and grace; the former the charms of simple modesty and innocence. His former empress used every art to support or enhance her personal charms; but with so much prudence and mystery, that the secret cares of her toilette could never be traced--her successor trusted for the power of pleasing to youth and nature. Josephine mismanaged her revenue, and incurred debt without scruple. Maria Louisa lived within her income, or if she desired any indulgence beyond it, which was rarely the case, she asked it as a favour of Napoleon. Josephine, accustomed to political intrigue, loved to manage, to influence, and to guide her husband; Maria Louisa desired only to please and to obey him. Both were excellent women, of great sweetness of temper, and fondly attached to Napoleon. In the difference between these distinguished persons, we can easily discriminate the leading features of the Parisian, and of the simple German beauty; but it is certainly singular that the artificial character should have belonged to the daughter of the West Indian planter; that marked by nature and simplicity, to a princess of the proudest court in Europe. Bonaparte, whose domestic conduct was generally praiseworthy, behaved with the utmost kindness to his princely bride. He observed, however, the strictest etiquette, and required it from the empress. If it happened, for example, as was often the case, that he was prevented from attending at the hour when dinner was placed on the table, he was displeased if, in the interim of his absence, which was often prolonged, she either took a book, or had recourse to any female occupation,--if, in short, he did not find her in the attitude of waiting for the signal to take her place at table. Perhaps a sense of his inferior birth made Napoleon more tenacious of this species of form, as what he could not afford to relinquish. On the other hand, Maria Louisa is said to have expressed her surprise at her husband's dispensing with the use of arms and attendance of guards, and at his moving about with the freedom of an individual; although this could be no great novelty to a member of the imperial family of Austria, most of whom, and especially the Emperor Francis, are in the habit of mixing familiarly with the people of Vienna, at public places, and in the public walks. From this date may be traced the declination of Napoleon's greatness. In the field he was generally unsuccessful, and occasionally murmurs of discontent were whispered by citizen and soldier. The plot thickens in the eight volume, and his abdication of the throne of France, and subsequent journey to Elba, are feelingly narrated by our author.
