The Guide consists of 56 pages, 42 pages of step-by-step detailed text and 14 pages of large clear illustrations, and is formatted for easy use by students. Large 12pt type, double-spaced paragraph separations, and no page breaks within paragraphs make for easy "following along" and quick reference during dissection. The large, page-sized illustrations are easy to view and if left unbound they can be placed side-by-side with their various text references.

The pages outlined in blue in the thumbnails may be previewed full size by clicking.
