This was the first of a series of inter-related art instruction books planned by Watkiss. (He self-published two additional small volumes: on key muscles and garments.)
2 color plates and 55 black & white sheets printed on one side only.
John's description of the book: "The Progressive Anatomy book involves abstract reductionism of the body from head to foot page by page of all muscle grouping throughout this volume. It concludes with the big issue of composition and placing the figure intelligently on the page. With further references to knowledge over style."
From the book: "I intend to introduce anatomy in a pattern like way by means of straight lines of action which will give an exposition of symmetrical and asymmetrical elements alike. Composition at its most sublime is composed elements within and without the forms of [the] human body."
Contents: Analysis of The Head, The Rib Cage, The Chest & Shoulder, The Arm, The Hand, The Head Chest & Hips, The Hip & Abdomen, The Leg, The Foot, The Full Figure.
