Query: first-rate book

The 6th edition of this book continues its excellent tradition. It is clear, concise and readable. What makes this book (and others from the series such as Pathology Illustrated) so excellent is that they can actually be read cover to cover in a short period of time. The value of this book to the student or teacher of physiology cannot be overstated.
