Rh notice. The first lecture was published under the title of an Introduction to Philosophy, and brought most flattering praise to the author from contemporary students. In an animated style the disciple of Jean Jacques Rousseau, the apostle of bold and ingenious ideas, was already beginning to declare herself. In the meantime she collaborated on the journal The New Economist, which the historian and sociologist Pascal Duprat had just founded.

At the close of 1860, the Canton of Vaud having opened a competition on the Principles of Taxation, "the little lady with a straw hat," as her neighbors familiarly called her, handled the subject so thoroughly that her memoir, entitled Théorie de l'Impôt et Dime sociale (Theory of the Impost and Social Tithe, 1862), won her the honor of dividing the prize with Proudhon.

In this introductory chapter she characterized the original and strong personality of Darwin in appropriate terms, saying: "While he has not the brilliant qualities of a Cuvier as a writer or a professor, he is at least a worthy heir of the profoundly philosophical science of the two Geoffroys Saint-Hilaire. . . one of those workmen who cut their stone with an
