Having reviewed the many disabilities which so long retarded woman's intellectual advancement, and considered some of the objections which were urged against her capacity for scientific pursuits, we are now prepared to consider the appeal of Christine de Pisan and deal with it on its merits. This we shall do by a brief survey of woman's achievements in the various branches of science in which she has been accorded the same intellectual opportunities that were so long the exclusive privilege of her male compeer. FOOTNOTES: [89] An edition of this work, based on an old manuscript in La Bibliotheque Nationale of Paris, in French, is announced to appear in France at an early date. An interesting account of this precious volume has recently been published by Mlle. Mathilde Laigle, Ph. D., under the title of _Le Livre de Trois Vertus de Christine de Pisan et son Milieu Historique et Litteraire_. It is to be hoped that some enterprising English publisher will soon favor us with a reprint of the quaint old, but none the less valuable, volume, _The Boke of the Cyte of Ladyes_.

[98] The importance of gray matter in mental processes has evidently been greatly overestimated, for it has been found to be thicker in the brains of negroes, murderers and ignorant persons than it was in the encephalon of Daniel Webster. It is also much thicker in the brains of dolphins, porpoises and other cetaceans than it is in the most intellectual of men. [99] _The Descent of Man_, Vol. I, p. 145, London, 1871.
