This is a well-edited collection of informed progress reports in endocrinology. The section on the central nervous system and the secretion of anterior pituitary trophic hormones is written by Mess and Martini. Their report includes an analysis of the evidence for "short" feedback control of certain pituitary trophic hormones (direct effect of trophic hormones on their own secretion) and the effects of hormones from certain "target" organs in causing release of pituitary trophic hormones.
In the section on control of corticosteroid secretion, James and Landon suggest that there would be increased use of indwelling needles for studies requiring multiple blood samples if investigators served more frequently as experimental subjects.
The sections on calcium (Foster and MacIntyre), glucose (Marks and Samols), thyroid (Galton), labor (Csapo and Wood), radio-immunoassay (Landon), renin (Brown, Fraser, Lever, and Robertson), and the cancer cell as an endocrine organ (Ross) are all well done. The section on
