posium is new. The papers included in this book were presented at a symposium in India in 1983. “Environment,” when broken down into separate units, is manyfaceted. Photoperiod, temperature, stress of various kinds (e.g., chemical pollution), dietary cycles, availability of dietary constituents such as iodine, osmotic influences, and social and behavioral interaction and alternation of the seasons-all of these are considered, but none of them exhaustively, Only vertebrate examples, from all classes, are considered.

The principal focus of this volume is on clinical neuroendocrinology. However, the focus is rather broad because the nine chapters range from the multiple forms of prolactin to control of food intake by human subjects. Of greatest interest to general endocrinologists is a chapter on multiple molecular forms of prolactin derived both from variant genes for the hormone and from post-translational cytoplasmic processing. Another useful review deals with the history of the isolation and se-
quencing of GRF, the hypothalamic leasing hormone for growth hormone.

Frontiers in Neuroendocrinology, Vol. 9. Edited by WILLIAM E GANONG AND LUCIANO MARTINI. RavenPress, New York. 282 pp.
“Frontiers in Neuroendocrinology” is a series of volumes that, beginning in 1966, have been published at approximately twoyear intervals. This volume contains 10 chapters, with the greatest emphasis on distribution in the brain of hormonal receptors (e.g., for corticosteroids, dopamine, CRF, angiotensin). Of unusual interest to comparative endocrinologists, the opening chapter provides an excellent review of the neuropeptides, their molecular precursors, and their physiology in Aplysia. Kalra develops a very complete model to explain the neuronal circuitry, hormonal sequences and actions, circadian clock regulation, and other neuroendocrine phenomena to explain the preovulatory L surge. The missing element in his well-designed scheme is sequential changes in receptor physiology. Two chapters illustrate an increasing awareness of possible paracrine actions of traditional hormones. They concern local action of endogenous angiotensin in the brain, and of a variety of hormones within the pituitary.
