expenditure. At this juncture we may also speak, of his change of name. It was the custom, as is well known, for the younger branches of noble families in France to assume the name of some estate, so to distinguish themselves from their relations. In the middling ranks the same custom was in a manner followed. Boileau took the name of Despréaux, and his younger brother that of Puy Morin, to distinguish themselves from the elder. People in this rank did not assume the _de_--distinctive of territorial possession. François-Marie Arouet thought it worth while, however, to purchase the estate of Voltaire (as Madame Searron, at Louis XIV.'s instigation, had that of Maintenon), as a means of elevating himself to a more respectable position in the eyes of his contemporaries. He succeeded; and though, to our ears, Arouet had sounded as well as Voltaire, did it stand in the title-page of his works; in his own day, in spite of various petty attacks from his enemies, the one he assumed was regarded by his countrymen with greater complacency. The heyday of youth was passing away with Voltaire; his vivacity was still the same: but, from the period of his return from his exile in England, he began to look differently on life; and while he still regarded literary labour as his vocation, literary glory as the aim of his existence, he grew indifferent to the pleasures of society. At one time he meditated expatriating himself; thus to acquire liberty of writing and publishing without fear of the Bastille. His attachment for madame du Châtelet caused him to alter this plan. This lady was distinguished for her learning, her love of philosophy, and talent for the abstruse sciences. She was witty, and endowed with qualities attractive in society; but she preferred study, and the acquisition of literary renown, in seclusion. This friend induced Voltaire to remain in France, but strengthened his purpose of retiring from Paris. Various persecutions were, however, in wait for him before he gained a tranquil retreat.
