LAMBERT (Madame), lived in Paris in 1840. She was then at a very pious age, "played the saint," and performed the duties of housekeeper for M. Picot, professor of mathematics, No. 9, rue du Val-de-Grace. In the service of this old philosopher she reaped enormous profits. Madame Lambert hypocritically took advantage of her apparent devotion to him. She sought Theodose de la Peyrade, and begged him to write a memorial to the Academy in her favor, for she longed to receive the reward offered by Montyon. At the same time she put into La Peyrade's keeping twenty-five thousand francs, which she had accumulated by her household thefts. On this occasion, Madame Lambert seems to have been the secret instrument of Corentin, the famous police-agent. [The Middle Classes.]
