by Professor J. H. Middlemiss, Department of Radiodiagnosis, The Medical School, University of Bristol This book, for so long and so deservedly, has been a favourite and reliable guide for any person undergoing training in diagnostic radiology whether that person be doctor or technician. This new, largely re-written edition is even more comprehen sive. And yet throughout the book simplicity of presentation is maintained. Professor G. J. van der Plaats has been well known to radiologists in the English speaking world for more than three decades. He has been, and still is, respected by them for his vision, his thoroughness, determination and meticulous attention to detail and for his unremitting enthusiasm. The standard of radiography in the Netherlands throughout this period has been recognised as being of the highest quality, and this has, in no small measure, been due to the pattern set by Professor van der Plaats and his colleagues.
