Excerpt from Twelve Lectures on Comparative Embryology, Delivered Before the Lowell Institute, in Boston, December and January, 1848-9 We feel both pleasure and pride in being able to present to the public the following Course of Lectures. It is thefirst enterprise of thekind in this city, and has therefore been attended with unusual trouble and expense. Embryology has but recently become the subject of scientific investigation. Few persons have as yet entered Upon it, and in this country it may be considered as entirely new; but it is destined to have a most important influence in the future progress of Zoology, and greatly to modify the present classification of animals. Prof. Agassiz has embodied in his Lectures all that has been hitherto done abroad, and has added numerous observations of his own, made in this country, and in a form at once highly scientific and so illustrated, as to be interesting to the common reader. The application here made of Embryology to the improvement of the classification of animals is peculiarly his own, as he has shown in his fourth Lecture. The point of the Lectures is to demonstrate that a natural method of classifying the animal kingdom may be attained by a comparison of the changes which are passed through by different animals in the course of their development from the egg to the perfect state; the changes they undergo being considered as a scale to appreciate the relative position of the series. The language has been retained almost precisely as delivered by the Professor, because, although in many instances it wears a foreign idiom, yet it is peculiarly expressive, and possesses a charm which would be lost in the attempt to reduce it to Saxon phrases. In proof of the fullness and accuracy of Dr. Stone's phonographic report, and also of the value of the phonographic system, we are enabled to state that several gentlemen had the curiosity to compare a portion of manuscript which the Professor had read, in one lecture, with the report of it; when it was found that every word appeared precisely as written, except that one word was missing, which the Professor stated he had purposely omitted in reading.

In this pathbreaking book, a well-known feminist and sociologist--who is also the Founding Editor of Gender & Society--challenges our most basic assumptions about gender. Judith Lorber views gender as wholly a product of socialization subject to human agency, organization, and interpretation. In her new paradigm, gender is an institution comparable to the economy, the family, and religion in its significance and consequences. Drawing on many schools of feminist scholarship and on research from anthropology, history, sociology, social psychology, sociolinguistics, and cultural studies, Lorber explores different paradoxes of gender: --why we speak of only two "opposite sexes" when there is such a variety of sexual behaviors and relationships; --why transvestites, transsexuals, and hermaphrodites do not affect the conceptualization of two genders and two sexes in Western societies; --why most of our cultural images of women are the way men see them and not the way women see themselves; --why all women in modern society are expected to have children and be the primary caretaker; --why domestic work is almost always the sole responsibility of wives, even when they earn more than half the family income; --why there are so few women in positions of authority, when women can be found in substantial numbers in many occupations and professions; --why women have not benefited from major social revolutions. Lorber argues that the whole point of the gender system today is to maintain structured gender inequality--to produce a subordinate class (women) that can be exploited as workers, sexual partners, childbearers, and emotional nurturers. Calling into question the inevitability and necessity of gender, she envisions a society structured for equality, where no gender, racial ethnic, or social class group is allowed to monopolize economic, educational, and cultural resources or the positions of power.
