Transcriber's Notes

With the exception of several presumed typographical error which have been changed as noted below and the addition of a Table of Contents and label for the image of the rock slab, the text presented is that shown in the original printed version. The Greek charaters from which the scientific names were derived are diplayed slightly larger, green text. Lastly, the images of the slab available, even a higher resolution version, does not show the level of detail expressed in the text. Perhaps, at some point, a higher resolution scan of the original photographic film or plate may become available.
