DESCRIPTION OF FIGURES 1-8, PLATES 1-15
The word "Plate" refers to the physical pages on which the Figures were printed. The word is not used as an illustration identifier. The complete caption text from this section has been added to each Figure. In the original, Figures were labeled only with number and letter. Based on the author's age at time of publication, "Miss C. M. Reese" is more likely to have been his sister than his daughter.
The surface views were drawn, under the author's direction, by Miss C. M. Reese. The first two of these views were copied, by permission, from S. F. Clarke; the others were drawn from the specimens themselves.
All of the figures of any one stage are given the same number, followed by distinguishing letters, so that it is possible to tell at a glance what figures belong together.
All of the figures except those from Clarke were drawn under a camera lucida.
