chapter 1, tier2, textual level
This site is structured in 3 tiers. The first tier (1) is HOME; there is no “NEXT PAGE” at tier 1. HOME is a single chapter (i.e., a “page” - as something other than the formatted page produced by a printer). At the end of each chapter, there is a pale yellow navigation bar; it is designated, NEXT PAGE. This bar is inoperative at the end of the HOME page. The reader is currently at the second tier; this tier is textual and consists of multiple chapters. The third tier is pictorial and also consists of multiple chapters (The NEXT PAGE navigation bar should be operative at levels 2 & 3). Illustrations of the third tier are identified as to chapter (c), tier (t), and drawing (D) or pictorial (P). Drawings are numbered in sequence without respect to chapter. In a similar fashion pictorials are numbered in sequence. The pictorials are technically flawed. They are not the same illustrative material submitted with the rejected manuscript. They were prepared in 1994 for a talk. In preparing for the talk, time was of the essence. The exit lens of the photomicroscope was covered with fragments of film; contamination of the exit lens of this particular camera was a common source of shadows on the finished product; the film transport would eat the film.
In the Master Border to the left, there are several navigational aids. The first, in sequence, near the top of the page, is a cluster of black bars providing access to the chapters of the first, second, and third tiers. The current page is tier 2, chapter 1. At tier 3, the numbering of chapters begins again. The next aid in descent along the Master Border will take the reader to material of a different nature on this same site; the reader will gain access to a variety of unusual melanocytic lesions. The next aid down the border to the left provides access to drawings. The next aid in sequence provides access to photomicrographs. The lnext aid in the border provides access to chapters at level 2 (textual chapters) and Pictorials. At the end of each chapter, a yellow navigational bar provides access to the next chapter in sequence at the same level as the selected navigational bar (with the exception of HOME). The chapters are not all of equal length but the limitations of the software require the commitment of space, often beyond the limits of the text. There is also a cluster of general navigation bars providing access to tiers 1 & 2 at the end of each chapter.
