Growth, Nutrition, and Metabolism of Cells in Culture, Volume 1, summarizes the state of knowledge of the growth, nutrition, and metabolism of various types of cell cultures. The chapters are both detailed and comprehensive enough for the specialist and broad enough to provide a general background for the nonspecialist. The present volume discusses the uptake, synthesis, and degradation of biologically important compounds, particularly the major components usually present in tissue culture medium. The book begins by tracing the history of the development of tissue culture. This is followed by separate chapters on early development of cell culture nutrition; the biological effects of serum; the energy metabolism of malignant cells; the gaseous environment of the mammalian cell in culture; and the uptake and utilization of amino acids by cells in culture. Subsequent chapters cover purine and pyrimidine metabolism; lipids in cell culture; the use of cell cultures for sterol metabolism studies; the genetic expressions of human diploid fibroblast cell cultures; and structural features of mammalian complex carbohydrates.

Modesty, which may be provisionally defined as an almost instinctive fear prompting to concealment and usually centering around the sexual processes, while common to both sexes is more peculiarly feminine, so that it may almost be regarded as the chief secondary sexual character of women on the psychical side. The woman who is lacking in this kind of fear is lacking, also, in sexual attractiveness to the normal and average man. The apparent exceptions seem to prove the rule, for it will generally be found that the women who are, not immodest (for immodesty is more closely related to modesty than mere negative absence of the sense of modesty), but without that fear which implies the presence of a complex emotional feminine organization to defend, only make a strong sexual appeal to men who are themselves lacking in the complementary masculine qualities. As a psychical secondary sexual character of the first rank, it is necessary, before any psychology of sex can be arranged in order, to obtain a clear view of modesty. The immense importance of feminine modesty in creating masculine passion must be fairly obvious. I may, however, quote the observations of two writers who have shown evidence of insight and knowledge regarding this matter. Casanova describes how, when at Berne, he went to the baths, and was, according to custom, attended by a young girl, whom he selected from a group of bath attendants. She undressed him, proceeded to undress herself, and then entered the bath with him, and rubbed him thoroughly all over, the operation being performed in the most serious manner and without a word being spoken. When all was over, however, he perceived that the girl had expected him to make advances, and he proceeds to describe and discuss his own feelings of indifference under such circumstances. "Though without gazing on the girl's figure, I had seen enough to recognize that she had all that a man can desire to find in a woman: a beautiful face, lively and well-formed eyes, a beautiful mouth, with good teeth, a healthy complexion, well-developed breasts, and everything in harmony. It is true that I had felt that her hands could have been smoother, but I could only attribute this to hard work; moreover, my Swiss girl was only eighteen, and yet I remained entirely cold. What was the cause of this? That was the question that I asked myself."

Biology of Fertilization, Volume 1: Model Systems and Oogenesis is the first in a three-volume series that gathers various lines of research about reproduction in general and fertilization in particular. Knowledge about cell biology, immunobiology, biochemistry, biophysics, and molecular genetics has progressed significantly beyond our understanding of some aspects of fertilization. Components of these constitute ""model systems."" The present volume includes reviews of such systems, some relatively simple model systems in lower organisms, sex-determining mechanisms, and oogenesis. The book contains 12 chapters organized into two sections. Section I includes studies on evolution, reproductive success, and immortality of the germ line; the structures and mechanisms involved in fertilization problems; and fertilization in Paramecium. Section II on oogenesis includes studies on gamete differentiation; sex-determining role of the H-Y antigen in mammals and non-mammals; the mechanism of starfish oocyte maturation; meiotic arrest in animal oocytes; and the mitotic and meiotic aspects of the mammalian germ cell life cycle.
