Bethesda: National Institute of Neurological Diseases and Blindness, October 1963. Paperback. 165p., no illustrations, text reproduced from a keyboard-set ms and stapled under printed cover sheets --no spine strip, rather crude but does the job. Mild edgewear, staples begun to rust, slight general toning of textblock and slight dust-soil to covers. A good copy, sound, clean and unmarked. Study of Child Growth and Development and Disease Patterns in Primitive Cultures.
